摘　　要：干旱是一个困扰我国农业发展的重要因素,作物生产一定程度上依赖防旱抗旱手段的提高,利用抗旱剂能缩小作物气孔开张度、抑制蒸腾作用、增加叶绿素含量、提高根系活力、减缓土壤水分消耗,从而增强作物的抗旱能力。抗旱剂可以调控作物的生长发育和生理生化,增强作物在逆境下的适应能力,提高耐旱性,使作物增产,应用前景广阔。近年来,一些作物抗旱剂应用在小麦、玉米、水稻等农作物上均取得了较好的抗旱增产效果。Drought is one of the most important factors which chronically affect China＇s agricultural development, and the crop production relies heavily on improving means of preventing and resisting drought of human beings. By means of using drought - resistant agents can have the function and role of reducing the degree of open of stoma , inhibitting transpiration, increasing the contain of chlorophyll and activity of root, reducing soil moisture consumption, and thus increasing the drought resistance of crops. By chemical methods, the physiological and biochemical process and the growth and development of crops are regulated and controlled. And the adaptability of resistance of crops under water stress is enhanced, the plant drought tolerance of crop yield is improved . It opens up new ways for the drought - resistance and increasing yield of crops. In recent years, some drought - resistant agents used in wheat, rice, corn, cotton and other crops have achieved good effects in drought - resistance and increasing yield.
