low pressure application

Effects of low pressure multi hole sprinkler irrigation on crop water requirement, farmland microclimate conditions and water use efficiency in wheat cotton intercropping system are investigated.

通过在中国农科院商丘试区实施低压管喷 ,结合麦棉套种作物需水特点、农田小气候相互关系进行了农业高效用水研究与实践 ,揭示出低压管喷麦田较连续畦灌节水 4 5%～ 4 7%,棉田较连续沟灌节水 4 3 %,小麦和棉花水分生产效率达 1 。
