宁夏扬黄延伸区限额灌溉保证率与产量关系研究
Study on relationgship between limited irrigation guarantee rate and yield in pumping irrigation extended district of Ningxia
摘要
Abstract
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.关键词
