在深耕密植和多肥的条件下,实行浅灌、湿润灌溉、晒田是预防倒伏的重要措施,也是我区农业生产大跃进以来的主要经验。因为浅灌、湿润可以提高水温、地温,易于通光透气,促进土壤微生物的活动,加速有机质肥料的分解,有利于根系的发育;晒田可以促使根系向深广度发展,形成发达的根群。实行浅灌和湿润灌溉,田间湿度较低,茎秆和叶片含水量相应减少因而迅速变老,节间粗而短,机械组织变硬,因而增强了抗倒伏的作用。要把浅灌、湿润灌溉和晒田三者正确结合起来,其中浅灌是基础。湿润灌溉和晒田要根据水利条 Under the conditions of deep cultivation of dense and fertile soil, shallow irrigation and wet irrigation are the important measures to prevent lodging and also the main experience since the great leap forward of agricultural production in our district. Because shallow irrigation, wetting can increase the water temperature, ground temperature, easy to breathe light, and promote soil microbial activity and accelerate the decomposition of organic matter fertilizers, is conducive to the development of the root system; Sha Tin can promote the root system to a wide range of development, the formation of a developed root group. The implementation of shallow irrigation and wet irrigation, field humidity is lower, the corresponding decrease in stem and leaf moisture content and thus rapidly aging, internodes coarse and short, mechanical tissue hardening, thus enhancing the role of lodging resistance. Shallow irrigation, wet irrigation and drying field should be the correct combination of the three, including shallow irrigation is the foundation. Moist irrigation and drying field according to the water strip
