膜下滴灌灌水周期对盐渍化土壤水盐运移影响研究
Influence of Irrigation Frequency of Drip Irrigation under Mulch on Soil Water-Salt Transport of Salinization Soil
摘要
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 7 days was the highest,and the lowest was appeared with irrigation frequency for 3 days in soil layers of 0～60 cm; soil salinity was reduced effectively with irrigation frequency for 7 days,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 7 days.关键词
