Water and Salt Transport of Cotton Field under Film Drip Irrigation

Gong Jian

Abstract

Field experiments were conducted to analyze the changes of soil water content and soil salt content of cotton field in different drip irrigation times.The results showed that the soil salt content and soil water content had a negative correlation,and drip irrigation could leak salt.With the extension of drip irrigation time,the effect of drip irrigation on leaking salt was reduced.Drip irrigation for 1year had a significant effect on the leaking of soil salt,especially in 0~40cm soil.
