Abstract
A cotton field experiment under mulched drip irrigation of soil salinization was carried out in order to study the effects of different irrigation frequencies on soil water-salt transport of salinization soil and cotton yield.The results showed that the moisture content with irrigation frequency for 7days was the highest,and the lowest was appeared with irrigation frequency for 3days in soil layers of 0～60cm;soil salinity was reduced effectively with irrigation frequency for 7days,which could effectively control the uprise of soil salt.The irrigation frequency had a significant influence on cotton yield,and the highest yield was obtained under irrigation frequent for 7days.
