摘要
作物生产很大程度上依赖于人类防旱抗旱手段的提高。利用作物抗旱剂,通过化学调控的方法,调节和控制作物的生长发育和生理生化过程,增强作物在水分胁迫逆境下的适应能力,提高植株耐旱性,为作物抗旱增产开辟了新的途径,具有广阔的应用前景。近年来,作物抗旱剂应用在小麦、水稻、玉米、烟草、棉花、马铃薯及蔬菜等农作物上均取得了较好的抗旱增产效果,根据相关文献资料,综述了作物的抗旱性、抗旱剂及其在提高农作物抗旱性上的应用效果与生理基础,并阐述了作物抗旱剂应用中的问题及前景展望。
The increasing of crop production depends largely on the enhancing of drought resistance of crops. It is a new way out to regulate and control the growth and biochemical process of crops by chemical measures to enchancing the drought resistance of the plants. In recent years, the application of drought-resistance chemicals of crops has acquired obvious effects on wheat, rice?maize, tobacco, cotton, potato and vegetables so on. This paper summarizes the drought-resistance mechanism of crops?the varieties of drought-resistance chemicals, and its effects of application and physiological elements.
