摘要
作物的田间耗水规律是制定灌溉制度的主要依据,利用肇州县作物需水量试验区2000~2012年测坑和田测的作物需水量实测资料,对主要作物耗水量、需水量、缺水量以及生育期内降水量与产量的关系进行了分析,确定了三种作物在不同灌溉条件下的需水量,为制定灌水决策和灌溉制度打下基础。
The water consumption rule of the crop is the main basis for the establishment of irrigation schedule.Based on the test pit and field test data of water consumption in 2000to 2012in the water consumption experiment area of Zhaozhou County,the relationship among the water consumption,water requirement,water deficit amount,the precipitation in the growth period and yield is analyzed.The water requirement of three crops under different irrigation condition is determined,which can provide basis for the decision of irrigation schedule.
