在库尔勒垦区,小麦常于开花、灌浆期因受干热风影响而减产10％左右。为减轻干热风对小麦的危害,我们于1985年对小麦喷洒无毒高脂膜,作防御干热风的小区试验,1986年又进行大面积推广,效果均良好。 无毒高脂膜(农七师柳沟化工厂产)是高级脂肪醇类长链化合物,具有成膜特性,兑水稀释后喷洒在植物体表,可形成一层肉眼看不到的薄膜,这种薄膜在潮湿条件下和一定时间内能随植株的生长而扩大,小麦在此膜的保护下,可减少体内水分散失。现将试 In Korla reclamation area, wheat is often flowering and the grain filling rate is reduced by about 10% due to dry and hot wind. In order to reduce the harm of dry and hot wind to wheat, we sprayed the wheat with non-toxic and high-fat film in 1985 for the plot test of defensive dry-hot wind. In 1986, we conducted a large-scale popularization and achieved good results. Non-toxic high-fat film (agricultural seven division Liugou chemical plant production) is a long chain of high-fatty alcohol compounds, with film-forming properties, diluted with water after spraying on the plant surface can form a layer of naked eye can not see the film, This film in moist conditions and within a certain period of time with the growth of plants to expand wheat under the protection of this film can reduce the body of water loss. Now test
