| 摘 要： | 毛细节水灌溉作为一种类似滴灌的新型灌溉技术逐渐得到关注。在室内模拟了毛细管水分在蔗区沙土、壤土和黏土中的运移情况。通过室内试验和HYDRUS-3D建模分析表明:土壤类型对土壤各方向入渗有明显的影响,水分运移速度和土壤各方向湿润范围顺序为:沙土壤土黏土;3种土壤含水率等值线变化规律基本一致,同样湿润位置土壤含水率顺序为:黏土壤土沙土。根据毛细管的水分在沙土、壤土和黏土运移规律,提出毛细管在蔗区沙土、壤土和黏土的合理埋深应为40、30和20cm。

Research on Soil-water Movement Characteristics Under the Condition of Kisss Irrigation |
| |
| Abstract: | As a drip irrigation method ,Kisss irrigation have already been paid attention gradually .This experiment simulates the soil water movement in sandy soil ,loam soil and clay soil under the condition of Kisss irrigation .The results show that the soil-water mi‐gration velocity in the sandy soil is higher that in the loam soil ,and that in the clay soil is the lowest .The variation law of soil-water content is basically consistent .The soil-water content in the clay soil is higher that in the loam soil ,and that in the sandy soil is the lowest .Based on the results of this experiment ,it is put forward that the reasonable depth of capillary for sand ,loam and clay in sugarcane area should be 40 ,30 and 20 cm ,respectively . |
