Are the sun and the solar system to the sun as the center, dominated by its gravity and the objects around it sports posed by the system . Members include the sun, Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus, Neptune, Ming Wang, more than 2000 asteroids 34 satellites, as well as a lot of comets and meteoroids. The sun (Sun) The center of the solar system objects. Are a star. Contains nearly 98% of the solar system quality. With the Earth's average Distance of 149,600,000 kilometers diameter 1,390,000 kilometers, to the Earth 109 times the volume of the Earth's 1.3 million times, Ping Are the density of 1.4 grams / cubic centimeter. Surface temperature of about 6000 degrees Celsius, the center temperature of 15 million degrees Celsius. By Nuclear fission of hydrogen nuclei into helium thermonuclear reaction a large amount of energy. The naked eye we see the surface layer called the "light ball" , Light balls above a layer called the "chromosphere", the most outer layer called the "corona", which formed the sun's atmosphere. Too Yang's rotation period is 25 days, the bipolar area is about 35 days, the sun on the most abundant chemical element hydrogen. The sun's activity stems from its central part. The sun's core pressure of more than 34 billion times the Earth. Here at hair Health of nuclear fusion. Fusion led to the four proton or a hydrogen atom or helium nuclei阿尔法粒子. Al Law on the quality of particles smaller than 0.7 percent to four protons, the quality of the remaining energy is transformed into the sun and was released to the table Noodles, and through the process of emitting light and heat convection. Solar core, through millions of years of energy required to reach Its surface. Per second have been 700 million tons of hydrogen into helium. In the process, there are about five million tons of net energy Volume was released, so the sun can make light-emitting. Photosphere are the chromosphere above. Amount of solar power through the region from the center outward transfer. This layer can be seen too Yang flares. Flares sunspots are formed before the chromosphere the hydrogen generated by hot clouds. Photosphere at some Region, a slightly lower temperature than the surrounding (usually 4000 degrees Celsius), this is the sunspot. The sun's outer atmosphere called the corona. Date the region has bait. Date baits are the upper chromosphere at the enormous Flame. The most coronal extension of outer space-oriented and radiation generated by the particles from the sun. Coronal only have the whole day Can be seen when fresh. The sun's age of about 46 million years, it can continue to burn about 50 million years. At the final stage of its existence, too Yang will be in the helium into heavy elements, the sun will also be the beginning of the volume continues to expand, until the Earth swallowed. At 一亿年After the red giant stage, the sun will suddenly collapse into a white dwarf - all stars of the existence The final stage. Go through several万亿年, it will eventually completely cooled. Mercury (Mercury) Ancient China, also known as "辰星." The sun, one of the nine planets. From the sun recently. With solar distance 0.39 Astronomical units, that is 57.91 million kilometers in diameter for 38% of the Earth, mass of the Earth's 5.5%, density of water 5.4 times larger orbit eccentricity, 0.21. Revolution period of 88 days, the rotation period of 59 days. For The sun side of the temperature of 400 degrees Celsius, while the sun back to -160 degrees Celsius, Mercury has many craters on And has a strong magnetic field, the surface strength of 1% of the Earth. Shell by the porous soil, or similar surface soil of the moon rock Composed of stone powder. Mercury is even lower than Jupiter's satellite Ganymede (Ganymede) and Saturn's satellite Titan (soil Titan) is also small. Mercury surface similar to the lunar surface. Meteorite dust covered the ups and downs撞成hills, a few kilometers of the fault cliff high Stretching hundreds of kilometers, large and small craters are everywhere. Looks at the sun than the Earth on large two and a half times. Because of not enough air to scatter sunlight, the sky is usually dark. If you look up to the sky, he also Xu will find two bright stars: a bright yellow are the Venus, the other one is blue earth. On observations from the Earth, Mercury and the sun angle of the largest only 28 degrees at dawn or during the day it appeared in the sky , So its observation very difficult. In the "sailors" on the 10th visit the Mercury before the awareness of Mercury are Very small. Because of its revolution and rotation of the relationship between the more complex, if the sun to rise from the sun for a Down Units to calculate, on the day of Mercury will be the day the Earth 176. Mercury appears that it can not exist on the water, its atmosphere is very small, and very high temperatures during the day. However, in 1991 Mercury at the Arctic scientists found an unusual bright spot. Highlights the possible cause of this are at the surface Or underground ice. Because the orbit of Mercury is rather special, at its North Pole, the sun is always on the horizon only irresolute Further. At some of the internal crater may never see the sun because of the temperature dropped to -161 degrees Celsius . Such a low temperature is likely to solidification from the planetary internal release of gas, or accumulation of ice from space . Mercury atmospheric pitiful, its main components for helium (42%), Sodium vapor (42%) and oxygen (15%), and its The average surface temperature of 179 degrees Celsius, up to 427 degrees Celsius, a minimum of -173 degrees Celsius. Venus (Venus) Ancient China, also known as "Venus", "Chang", "Taibai", "star" and so on, the nine planets of the solar system 1. According to the order from the sun for the second. With an average distance of the sun 0.72 astronomical units, 108,210,000 Km. Size and the Earth is similar to the diameter of the Earth smaller than 5%, quality 82% of the Earth, the density of water, 5 .2 Times the revolution period of 225 days, the rotation period is 243 days, the rotation direction and the other planets the contrary, the surface cover Covered a very thick atmosphere, the most carbon dioxide, oxygen and water vapor low surface temperature as high as 480 degrees Celsius About. Venus surface of the magnetic field only one-thousandth of the Earth also has an ionosphere. Separately in the morning because of Venus Morning and evening in the sky, the ancient astrologers have been think there are two such planets, then sub - Do not be referred to as the "Morningstar" and "evening." In English, Venus - "Venus" (Venus) is an ancient Romanian Horse of the god of love and beauty. It has always been curly clouds shrouded in mystery at. Because of Venus and the Earth in size, mass, density and weight on very similar, and almost all of Venus and the Earth Formed simultaneously by the same nebula, astrologers will have them as sister planets. But recently scientists have discovered , Venus and the Earth in fact very different. Venus has no oceans, it has been the main ingredients for a thick oxide Carbon in the atmosphere surrounded by water does not. Its cloud is composed of sulfuric acid droplets. At the surface, it Equivalent to atmospheric pressure at sea level on the Earth 92 times. Because of Venus's thick atmosphere of carbon dioxide caused by "greenhouse effect", Venus surface temperature up to 482 photo S degrees. Sunlight through the atmosphere will be hot roast Venus surface. Surface outward radiation of heat at the process by Atmospheric barrier, can not be distributed into outer space. This makes Venus than in Mercury also hot. Random surface of Venus is covered with many small craters. Because of Venus's thick atmosphere, a diameter less than 2 kilometers Crater is almost impossible to retain it. And when a large meteorite in a small pit formed before the meteorite hit the surface of Venus, and its production Health and debris at the surface of the crater produced exceptional group. Volcanoes and volcanic activity of a lot of the surface of Venus. To Less 85% of Venus surface covered with volcanic rocks. Many lava flows hundreds of kilometers, fill the lowland, forming a broad Wide plains. In addition to hundreds of large volcanoes, more than 100,000 small crater Block embellishment at the surface of Venus. From fire Mountain emitted lava flows resulted in a long trench, ranging up to hundreds of kilometers, one of a range of ultra - Over 7000 kilometers. The topography of Venus is covered with vast lava plains and mountains of geological activities undermine or plateau. At Maxwell Hill Ishtar region are the highest mountain on Venus. Aphrodite highland region occupies almost Half of the equatorial regions. Magellan plans to obtain more than 2.5 kilometers of Venus images show the existence of the plateau zone prescribed Bright soil moist. However, in the Venus surface, liquid water are unlikely to exist, and could not explain the bright plateau Reasons. There was a presumption that these bright regions may be due to metal compounds. Studies have shown that this Some metals may be iron sulfide. It can not exist in the plain areas, but at high altitude is possible. These payments May also be an alien, and it led to the effect is the same, but the concentrations are lower. The Earth (Earth) The nine planets of the solar system, according to the order from the sun for the third stars, with the sun's average distance of about 14,960 10,000 kilometers, the volume of around 1,083,200,000,000 cubic kilometers for the equatorial radius is about 6378 kilometers, the radius is extremely 6,3 57 kilometers, a difference of 21 kilometers. The average water density is 5.5 times the revolution period is 365.25 days, the rotation cycle 2 3:56. Revolution of the Earth orbit is an ellipse with the Earth equatorial plane into 23 degrees 26 minutes angle. So generated The length of the seasons and day and night. Surface has a solid crust. An area of 51,100 km, one of the total marine table Area of 71%, land is about 29%, surrounded by the atmosphere, nitrogen, oxygen, water vapor and other gas components. Earth Has a satellite - the moon. Used to distinguish the characteristics of the Earth are on a black background and blue water, brown and green Land and the large white cloud. We are the Earth's atmosphere is 78 percent nitrogen, 21% are oxygen, the remaining 1 percent are other ingredients. Flat surface of the Earth Both the temperature is 15 degrees Celsius, the mean pressure of 101.3 Pa. The Earth are the only known solar system planets existence of life. Express our planet's rotation and nickel iron lava nuclear Heart to generate a vast magnetic field, together with the atmosphere to prevent almost all from the sun and other stars Harmful rays. The Earth's atmosphere for us to block a lot of meteorites, meteorite much at their arrival and before the Had been burned. Since the beginning of human space exploration, our own planet there is a greater awareness. The first man-made human beings to Ball satellite discovered a strong radiation zone, now called the Van Allen radiation belts. The causes are from Sports Express in the charged particles in the equatorial region of a circular region to capture the Earth's magnetic field. Earth's magnetic field By the solar wind into a droplet-shaped twist of this phenomenon is also found by satellite. We also found that once we identified Is very calm for the upper atmosphere, they are very active, and it during the day and evening to narrow expansion. Live by the sun Dynamic effects of the Earth's upper atmosphere to affect weather and climate. Apart from the impact of the Earth's climate, the sun's activities are also our atmosphere for the brilliant performances. When the charged particle Son of the Earth's magnetic field has been captured, they are with our planet's pole impact air molecules so that these open air molecules Sending light, this is the "Aurora." Mars (Mars) Ancient China, also known as "荧惑," the nine planets of the solar system, according to the order from the sun for the fourth stars. And too Yang average distance 1.52 astronomical units, or 227,940,000 kilometers in diameter for 53% of the Earth, its size at Ranked seventh in the solar system. Quality for 11 percent of the Earth, the density of water is 3.9 times the revolution period of 687 days, Rotation cycle of 24 hours 37 minutes. Mars's equatorial plane and orbital plane 23 degrees 59 minutes into the corner, so on Mars also has Four Seasons, a quarterly basis and around six months long. Very thin atmosphere, mainly composed of carbon dioxide, the surface temperature at Chek Road during the day and the highest, at 28 degrees Celsius, down to -132 degrees Celsius at night, white极冠of the main components of water ice Also has a small amount of dry ice, the size of极冠changes with the seasons. Sometimes disappear in summer and winter increase. Surface Comparing the same as the Earth has rocks, volcanic and desert regions. On Mars because of the rock, sand and sky are red Color or pink, so the planet is often also referred to as the "red planet." The southern hemisphere of Mars are similar to the moon covered with craters of the ancient plateau, while the Northern Hemisphere, mostly organized by young plains Composition. Mars 24 kilometers high on the "Olympus" Mountains can be called the solar system are the highest mountains. Away from fire Stars around tens of thousands of kilometers, have two very small stars, which are the Martian satellites. In Chinese, the name is reminiscent of Mars to the "fire" and hot, but in fact, this red planet is Abnormal cold and dry. Nevertheless, Mars is still in the solar system and earth are the most similar to a planet. It Smaller than the size of the Earth, the atmosphere thinner than the Earth. A very thin atmosphere of Mars, the Earth's atmospheric pressure is only 7 thousandths. The main components of the atmosphere of Mars are dioxoketene CFCs, and other ingredients are nitrogen, argon, oxygen and so on. Mars atmospheric water at the proportion of only 0.03% . Thus abnormal drying the surface of Mars. Mars the average temperature of minus 55 degrees Celsius, while the larger temperature difference: In the summer, daytime temperatures up to Twenty degrees Celsius, while in winter the temperature can be as low as minus more than 100 degrees Celsius. Mars often have strong winds, And thus often leads to large-scale dust storms. Scientists have found that many areas on Mars have been signs of erosion, but it seems to criss-cross the riverbed Telling us that Mars once had liquid water, they gather into large and small lakes, and even marine . Scientists, it was explained that at the early formation of Mars, the planet by thick clouds of carbon dioxide The parcels, resulting in a powerful "greenhouse effect" by the solar radiation, heat the surface of Mars have been obstructing the clouds Separated, can not be distributed to the outer space, making temperatures rise, so that liquid water to exist. At that time, the warmth of the Martian Humid, you may have been bred to life. Mars has two poles at many solid-state carbon dioxide (dry ice), scientists have speculated that in these enormous ice Cover may exist below the water-solid. Jupiter (Jupiter) Ancient China, also known as "岁星," one of the solar system planets. According to the order from the sun for the Fifth stars. And too Yang average distance of 5.20 astronomical units, or 778,300,000 kilometers. Volume and quality than the other eight planets Combined, and the equatorial diameter of the Earth 11.18 times for the 142.8 thousand kilometers. The quality of the Earth's 317.89-fold , Density of water 1.3 times, public transfer cycle 11.86, the rotation cycle for the 9:50 is the fastest one rotation Stars, so the shape is very flat. Jupiter atmospheric shading shows staggered parallel to the equator of the cloud band, the temperature was about -12 1 degrees Celsius. Well-known Great Red Spot are embedded in the cloud band of clouds. Atmospheric thickness of about 730 kilometers. Atmospheric depths have Water vapor, but the total amount of less than hydrogen. There are acetylene, ethane and phosphine. Jupiter's magnetosphere has been a huge package Around with the Earth's magnetosphere similar to, but charged particles within the magnetosphere the energy of the radiation of the Earth is about one million times. Wood Stars than the Earth magnetic field strong 20-40 times, suggesting that Jupiter has its own energy. Jupiter has 13 satellites, consider someone There may be satellites fourteenth. There is a halo of Jupiter and Aurora
Chinese Holidays and Festivals Post By：2008-12-2 19:55:05 As well known, different countries have different customs and cultures. With the development of China, it has a rich and unique culture. The holidays and festivals in China are quite different from those in other countries. We have many traditional holidays and festivals. In addition, people in different areas also have their own local customs.New Year —元旦It falls on the first day of the year. It marks the beginning of a year. People will plan what to do in the new year. Because they believe that the whole year's work depends on a good start in spring.Spring Festival —春节Spring Festival is the most important festival in China. It is on the first day of the first lunar month(阴历正月). On the eve of the festival, people will paste spring poems(贴春联)with lucky words. They prepare delicious food, dumpling is a must. They also clean their house, but there is no sweeping on spring festival for people think it will sweep away good luck. People often come back home to enjoy family reunion, the whole family will get together for the big dinner. They also exchange greeting with other friends and relatives.Lantern Festival 元宵节It comes on the 15th of the first lunar month and it marks the end of the Spring Festival. On this day, people often eat sweet dumplings（元宵）for good luck. They will visit the display of lanterns(灯展)or go to temple fair(庙会)Qingming 清明节Qingming —It is also called Tomb-Sweeping Day. It falls on April 4th or 5th . That is a special day for the living to show love and respect to their dead friends or relatives. People often go to sweep the tomb and put the meat, wine in front of the tomb. One interesting thing is that people burn the paper money for the dead. Dragon Boat Festival 端午节This day is on the fifth of the fifth lunar month, People often get together to watch the wonderful “Dragon Boat Race”(龙舟大赛)，Rice Dumpling(粽子) is a must on Dragon Boat Festival. People eat Rice Dumpling in memory of the famous poet-屈原who died on this day many years ago.Mid-autumn Day —中秋It comes on the 15th of the eighth lunar month. People often gaze at the “Lady in the moon”(嫦娥) and eat moon cakes. The Mid-autumn Day also means harvest
泰哥，我给你找了几个，必须采纳啊！ To Pull up the Seedlings to Help Them Grow “拔苗助长” Once upon a time, there was an old farmer who planted a plot of rice. After he planted the seedlings, every day he went to the field to watch the seedlings grow. He saw the young shoots break through the soil and grow taller each day, but still, he thought they were growing too slowly. Eventually he got impatient with the young plants and suddenly he hit upon an idea that one by one, he pulled up the young plants by half an inch. The next early morning, the young man couldn’t wait to check his “achievement”, but he was heart-broken to see all the pulled-up young plants dying. 从前，有个农夫，种了稻苗（seedlings）后，便希望能早早收成。每天他到稻田时，都发觉那些稻苗长得非常慢。他等得很不耐烦。想了又想，他终于想到一个“最佳方法”，他将稻苗全都拔高了几分。第二天，一早起身，他迫不及待地去稻田看他的“成果”。 哪知，却看到所有的稻苗都枯萎了。Plugging One’s Ears While Stealing a Bell “掩耳盗铃” Once upon a time, there was a man who wanted to steal his neighbor’s doorbell. However, he knew clearly that the bell would ring and catch the other people’s attention as long as he touched the bell. So he thought hard and suddenly hit on a clever “idea”. He plugged his ears with something, thinking that everything would go well when he stole the bell. Unfortunately to his disappointment, the bell still rang loudly and he was caught on the spot as a thief. 从前，有一个人想偷邻居门上的铃，但是他知道一碰到铃，铃就会响起来，被人发现。他想啊想，终于他想出一个“妙极”，他把自己的耳朵用东西塞起来，就听不见铃声了。但是当他去偷铃时，铃声仍旧响起来，他被别人当场抓住The Fox and the Crow “狐狸和乌鸦” One day a crow stood on a branch near his nest and felt very happy with the meat in his mouth. At that time, a fox saw the crow with the meat, so he swallowed and eagerly thought of a plan to get the meat. However, whatever the fox said to the crow, the crow just kept silent. Until the fox thought highly of the crow’s beautiful voice, the crow felt flattered and opened his mouth to sing. As soon as the meat fell down to the ground, the fox took the meat and went into his hole. 有一天,一只乌鸦站在窝旁的树枝上嘴里叼着一片肉，心里非常高兴。这时候，一只狐狸看见了乌鸦，馋得直流口水，非常想得到那片肉。但是，无论狐狸说什么，乌鸦就是不理睬狐狸。最后，狐狸赞美乌鸦的嗓音最优美，并要求乌鸦唱几句让他欣赏欣赏。乌鸦听了狐狸赞美的话，得意极了，就唱起歌来。没想到，肉一掉下来，狐狸就叼起肉，钻回了洞Draw a Snake and Add Feet to It “画蛇添足” Long long ago, several people had a jar of wine among them and all of them wanted to drink it by himself. So they set a rule that every one would draw a snake on the ground and the man who finished first would have the wine. One man finished his snake very soon and he was about to drink the wine when he saw the others were still busy drawing, so he decided to draw the feet to the snake. However, before he could finish the feet, another man finished and grabbed the jar from him, saying, "Who has ever seen a snake with feet?” The story of "Draw a snake and add feet to It.” tells us going too far is as bad as not going far enough. 古时几个人分一壶酒。他们都想独自喝完那壶酒，所以就定了一个规矩：每人在地上画一条蛇，谁画得最快，这壶酒就归谁。有一个人很快就把蛇画好了。他正打算喝这壶酒时，看见别人都还在忙着画，就决定给蛇再画上几只脚。结果，他的蛇脚还没加完，另一个人已经把蛇画好了。那人一下把酒壶夺了过去，说：“有谁见过长脚的蛇？”。这个故事告诉我们这样的道理：做得过分和做得不够都是不对的
草莓的灰霉病：又称烂果病，是草莓的主要病害之一。前期侵害叶柄、叶片、花蕾、花和果柄。采收期主要侵害果实，严重时可减产3～5成。叶上病斑初时为褐色湿斑，最后在叶背长出灰白色绒毛状物。果实发病，初时为褐色小斑，病斑扩大后，果面覆盖灰霉状物，直至全果腐烂。
草莓灰霉病在我国草莓产区普遍发生，是草莓栽培中为害普遍而且较为严重的真菌性病害，在露地和保护地中均可发病，温室内栽培的草莓发病尤为严重。主要为害叶片、花、果柄、花蕾和果实。
（1）为害症状 叶片和果柄上发病时，病部产生褐色或暗褐色水渍状病斑，湿润时叶背出现乳白色绒毛状菌丝团。花蕾和花柄发病时变为暗褐色，以后蔓延枯死；果实被害初期，出现油渍状褐色斑点，进而迅速扩大，至全果变软，密生灰霉，灰色霉状物病原菌的分生孢子梗与分生孢子。
（2）病原及发病规律 该病致病菌为半知菌亚门，灰葡萄孢属的灰霉菌（Botrytis cinerea Person）。病源菌以菌丝体、菌核、分生孢子的形态在病组织中越冬。在气温18～20℃，湿度达94%以上的条件下大量产生分生孢子，并借风力传播浸染，从伤口侵入为主。在气温20℃，连阴雨或灌水过多、地膜积水，以及栽植密度过大，通风透光不良等情况，均可诱发灰霉病的大发生。在保护地栽培中，温度在12～13℃以上湿度大的白天容易发病，夜间温度在10℃以下时不易发病。发病初期一般在2月上旬，3～4月达到高峰；露地草莓在果实采收期的5月份达到发病高峰。灰霉菌为弱寄生菌，多从伤口或枯死部位进行浸染繁殖，先危害枯芽老叶，然后危及果实。
（3）防治方法 ①避免过多地施用氮肥和灌水过多，增施磷钾肥，适当稀植，控制植株过旺生长，保证通风透光良好；保护地采用高垄滴灌栽培管理技术可降低发病率；②选用美国3号、红衣等抗病品种。进行地膜覆盖或果实垫草，防治果实与地面接触，及时摘除枯叶病果。③保护地栽培。可在开花和果实生长期。加大放风量，使棚内湿度降至50%以下，将棚室温度提高到35℃，闷棚2小时，然后放风降温，连续闷棚2～3次，有很好的防治效果。④药剂防治。从花序显露至开花前是药剂防治的关键时期，果实开始采收后应停止用药，以降低农药对果实的污染。可选用的药剂有70%甲基托布津可湿性粉剂500～1000倍液、等量式波尔多液200倍液、多氧霉素可湿性粉剂500倍液、克菌丹可湿性粉剂800倍液，或50%速克灵可湿性粉剂，或25%扑海因可湿性粉剂1000倍液喷雾等，每隔7～10天喷1次，连喷2～3次。保护地栽培时，还可每667米2用20%速克灵烟剂80～100克，分放到5～6处，傍晚点燃，闭棚过夜，7天熏1次，连熏2～3次，可起到良好的防治效果。
草莓灰霉病是目前草莓生产中的重要病害。我国各草莓种植区都有发生，特别是南方采果期是春雨期，发病更严重。草莓灰霉病的发生往往会导致花和果实的腐烂，对草莓产量和品质有很大的影响。一、症状显示：主要有害果实以火器渗透为主。病菌渗透花瓣后呈浅棕色斑，病斑迅速扩大到全板，碎片发病扩大到有果。潮湿后发病部位会发霉。生长期果实的发病大部分始于花萼包裹或边缘，形成浅棕色、水渍、轻微凹陷的不规则斑点，随着果实的增大，斑点增大，渗透到大部分水果面。病科软化，病部密生灰色霉菌。水果着色前发病，病夫很少形成分生孢子。成熟后发病可能会产生大量的分生孢子。
树叶发病很少，污迹、不规则型、棕色，大部分发生在叶片边缘，叶片背上出现灰色霉菌。二、疾病病原体：无性状态为灰色葡萄孢子，属于半真菌亚门葡萄孢子。盆生孢子茎丛生，直立，浅到棕色，280~550m12m~24m，最上面的树枝，枝顶微膨胀，孢子细胞多点萌发。分生孢子卵形、椭圆形、单生、正常生、无色至浅棕色、单细胞、大小为11 ~15m .病菌的分生孢子萌发温度范围为4 ~ 32，发芽积温为13.7 ~ 29.5，较低温度更有利于超真菌的繁殖。成泰是富氏菌核菌菌核病(debary) Fuckel。通常很少发生。菌核生于腐烂的水果，黑色，不规则型。这种病菌除了伤害草莓外。
还可以感染茄子、黄瓜、番茄、葡萄等多种植物。三、发病规律：病菌主要是菌丝，其次是菌核，在弊病和病州过冬。第二年产生了分生孢子，随着风雨传播。病菌以火器感染为主，可以直接入侵或从伤口入侵。在积温条件下伤口入侵的速度又快又严重。病部形成的分生孢子通过风雨和病的相互接触引起再渗透。草莓品种之间的抗病性差异不大。但是一般来说，欧美系统品种的京果型抗病性比较强，而延果型品种比较感病。温湿度是影响草莓灰霉病发生程度的重要条件。草莓生长在促进、半促进种植环境中，12~13h低温持续有助于病原体入侵和繁殖，不利于草莓生长，腐烂水果尤为严重。
相对湿度为64%，病例率不到10%。相对湿度可以达到80%以上连续7d，腐烂水果率达到30%以上。因此，温度适宜时湿度是导致灰霉病发生的主导因素。另外，氮肥的施用发病也很严重。四、疾病控制：草莓花期长，分裂结果不明显，采果间隔短。因此，草莓灰霉病的预防要以农业措施为基础，确保火器药物的预防。1.培育抗病品种：泰坦、小球藻、春香等抗病能力。2.清除弊病：冬春仔细清扫庭院，集中焚烧干枝、病叶和杂草。在北方，与地膜覆盖相结合，不仅可以减少越冬菌源，还可以减少死秧，加强植物抗性和生长势头，延缓幼苗，病害轻。3.加强种植管理：合理密植。
整叶果费，加强透明度，减少小气候湿度。下大雨的地区要采用高耕，注意排水。对脆弱病的品种，要调节氮肥的使用量，增加磷、钾肥。4.生物防治：以曲克或真菌T5为拮抗剂，用5106/ml孢子喷雾预防，预防效果达81%左右。5.药剂预防：草莓在露地、促进或半促进栽培条件下，药剂预防治疗的最佳时机是草莓一级花序开花20% ~ 30%以上，二级花序刚刚开花。有效药剂为满霉、速克灵、法海因、灰、霉菌、白菌清等，每7~10天喷洒一次，连续喷洒3~4次。放置药剂时要注意药剂的替代使用，延缓抗药性的出现。继续下雨的时候，可以选择百菌清、速克灵、灰霉青等烟草剂进行熏蒸。

阅读体验，真爽嘞！它内置的阅读器，属于又简约、功能又全面的那种。简约指的是，当你打开阅读页它默认预设的字体、字号大小、间距、背景等都非常干净舒服，没有任何多余元素打扰让你完全沉浸阅读。
功能全面指的是，当你单击屏幕中央会看到很多实用功能，你可以通过它们随时切换“轻读”、“书金”、“真传”、“一答，”，以每10条内容为一个阅读周期，减少阅读疲劳感，每天都在更新有趣、有料、富有意味的知识，供大家学习。
阅读同时，我们也可以和世界保持着沟通，给朋友做即时分享。说实话，这样资源丰富、完全免费又没有广告的阅读App，真的用一个少一个。
这不要放长假了嘛，大家看涨知识的需求也特别大，所以再费劲也得给大家安排上，希望大家珍惜住啊。
