摘要
在两种不同的土壤中 ,以不同滴头流量进行滴灌 ,通过对土壤湿润峰运移测量分析 ,提出不同土壤水分水平扩散和垂直扩散随时间变化的数学模型 。
Drop irrigation was carried out in various water flow in two kinds of soil.By measuring vertical and horizontal movement of water in soil,it was suggested that the relationship between vertical spread,and horizontal spread and time can be expressed by models According to the models,design parameters of drop irrigation,such as namely drop end flow,drop end interval distance and drop irrigation duration,can be determined for various crops.
