浑水膜孔灌入渗影响因素
Influence factors of muddy water film hole irrigation infiltration
摘要
Abstract
In order to reveal the difference of muddy water infiltration and clean water infiltration, through the test data of free infiltration of muddy water film hole irrigation, analyzing the influence of free water infiltration capacity of muddy water film hole irrigation, such as clay and sand grade,size of film hole,soil bulk density and initial soil water content were researched.The results show that various factors all have a significant impact on the film hole irrigation free infiltration capacity,putting forward the relationship between the influence factors and the infiltration capacity of muddy water film hole irrigation.The model of clay and sand grade,size of film hole,soil bulk density and cumulative infiltration volume per unit film hole area of free infiltration of muddy water film hole irrigation of initial soil water content and steady infiltration rate was established.Moreover its correlation coefficient is greater than 0.960 0.Based on the model, the cumulative infiltration volume per unit film hole area and steady infiltration rate can be obtained, further judging the free infiltration capacity in soil under muddy water film hole irrigation.The results could provide a reference for further studies of muddy water film hole irrigation free infiltration law and technology.关键词
