水稻是我国农药用量最大的作物。由于水稻叶片表面有很厚的蜡质层,清水在水稻叶片表面的接触角高达134°,属于极难润湿植物叶片,市场上购买的农药制剂,对水稀释后,雾滴在水稻叶片上的接触角也较大,不能形成很好的沉积分布,雾滴容易滚落。因此,在水稻上进行农药 Rice is China’s largest crop of pesticides.

It belongs to the very difficult to wet the leaves of plants and is purchased on the market. After the water is diluted, The contact angle is also larger, can not form a good deposition distribution, easy to roll off the droplet. Therefore, the pesticide on rice
