摘要
利用地面灌溉模型对波涌灌溉条件下地表水流及入渗过程进行模拟 ,在模拟结果与田间实测资料对比基础上 ,确定适宜的田间灌水参数 ,即土壤入渗强度、田块规格、田面坡度、入地流量、田间微地形等的变化范围 ,给出适合于波涌灌水方法应用的田间组合条件 ,提出波涌灌水技术对壤类土质的田间适应性 。
Field experiments on surge flow and continuous flow irrigation were conducted. And a computer model SRFR was used to simulate the surface flow phases under continuous and surge water application. The effect of each factor such as infiltrability, geometrical size of the field, field slop, intake flow rate and microtopography, etc. on performances of both irrigation systems was separately evaluated by means of simulations and observations to determine field parameters and conditions adaptable to the application of surge irrigation.
