随着科学技术的发展,与干旱作斗争已由传统的耕作、栽培技术防旱抗旱发展为化学、物理防旱法,其中抑制水分蒸发、蒸腾法更为实际而有效。 一、抑制蒸腾 1.薄膜法 用单分子膜覆盖叶面,阻止水气分子由气孔向大气中散失,就可抑制蒸腾。将十二醇、OED、蜂蜡、石蜡、椽胶乳液等的
With the development of science and technology, the struggle against drought has been transformed from traditional farming and cultivation techniques to drought resistance and drought resistance as a chemical and physical drought resistance method, in which inhibition of water evaporation and transpiration are more practical and effective. First, the inhibition of transpiration 1. Thin film method with a single molecular film covering the foliage, to prevent moisture molecules from stomata to the air dissipation, can inhibit transpiration.
