| 摘 要： | 通过观察,雨水能很好地在棉花、黄瓜、桃树等植物叶面铺展成水膜,能很好的沾湿石榴、扁豆、辣椒等植物,在叶面形成弧形或半圆形的水滴,但雨水不能使红花酢浆草、水稻、甘蓝等植物润湿,而是在叶面形成球形的水珠,极易滚落.大于31.25 mg/L TX-10水溶液和大于200 mg/L杀虫单-矿物油微乳剂的表面张力均小于水稻或甘蓝的临界表面张力,因此在水稻或甘蓝叶面能形成弧形或半圆形的水滴,很好地沾湿叶片,甚至可以在叶面铺展成水膜.

| Abstract: | The fact was found through the observation on nature phenomena that rain could wet and spread on the leaves of plants such as cotton,cucumber,peach,and so on,that rain could form drops of arc-shaped or semiround on the leaves of plants such as pomegranate,purple haricot,pepper,and so on,and that rain could not wet but formed water polo on the leaves of plants such as corymb wood sorrel,rice,cabbage,and so on,which would roll off the leaves easily.When the surface tensions of TX-10 solution more than 31.25 m... |
