根据定点定位试验结果 ,提出适用于华北平原现实经济、技术状况的农业节水实用措施 ;喷灌是一种低成本高效益的节水工程技术措施 ,秸秆覆盖和留茬可有效地进行农田界面调控 ;利用水分胁迫诱导的“反冲”机制 ,在农业生产中可以合理配置有限的水资源 ,达到节水稳产的目的。
According to the results of fixed-point positioning test, practical measures of agricultural water saving applicable to the actual economic and technical conditions in the North China Plain are put forward. Sprinkling irrigation is a low-cost and high-efficiency water saving engineering technical measure. Straw mulching and stubble can effectively control farmland interface Utilizing the “backflushing” mechanism induced by water stress, limited water resources can be reasonably allocated in agricultural production so as to achieve the purpose of saving water and ensuring stable production.
