中文摘要:

开展宁夏扬黄延伸限额灌溉区降雨频率分析,试验研究取得了不同限额灌溉定额对应的作物产量,分析了不同地区、在不同降水频率时作物的缺水量、在限额灌溉情况下的灌溉保证程度,以及不同灌溉保证程度与作物产量的关系,并提出在灌区尺度推广限额灌溉应该考虑扩大系数的取值范围。

英文摘要:

The paper analyzed the rainfall frequency of Ningxia limited irrigation area and got corresponding crop yield under the different limited irrigation quota. Through analyzing the shortage water in different area and various rainfall rate, irrigation guarantee degree of the limited irrigation conditions and the relationgship between the irrigation guarantee degree and the yield,the paper proposed appropriate expanding coefficient ranges of promoting limited irrigation in the irrigation district.
