摘要
通过对小麦和玉米生长期间的有效降雨量及灌溉水量、灌溉利用系数、灌溉水量及作物产量的关系分析计算 ,阐明了有效降雨量 ,充分利用有效降雨量合理进行灌溉 ,提高灌溉效益的方法。
By analyzing and calculating the effective precipitations, irrigation water yield and utilization ratio, and crop output during the growing period of wheat and corn, the writer expounds how to make full use of effective precipitations to make an appropriate irrigation and improve its benefits.
