摘 要:根据垄作沟灌水分入渗特点和灌水效果,对传统地面灌水质量评价指标体系进行了改进,建立了以灌水均匀度、储水率与田间灌溉水利用率、垄体湿润度4个指标组成的灌水质量评价指标体系,从减少测量工作量与便于实际应用的角度,对指标计算方法进行了简化,利用现场实例试验测定的灌水效果对该指标体系及简化算法进行验证,指标体系科学合理,计算简单可行。According to water infiltration characteristics and irrigation effect of ridge tillage using furrow irrigation,the evaluation indexes of irrigation quality of traditional surface irrigation was improved,an index system including irrigation uniformity,water storage rate and irrigation water use efficiency,the ridged body wetting degree was established for irrigation quality evaluation of this irrigation techniques. To reduce measuring work and facilitate the practical application,the index calculation method was simplified. This evaluation index system is scientific and reasonable,and its simplified calculation method is simple and feasible verified by using water content data measured in field of the case study.
