| 摘 要： | 在相同灌水量条件下,以不同比例混合地下咸水(3.56 g/L)和地表淡水(0.4 g/L),采用膜下滴灌方式充分灌溉棉田,探求土壤盐分的时空变化规律.研究表明,棉花生长期间土壤盐分的变化主要受土壤水分运移和地面植被覆盖度的影响;表层土壤盐分波动大,深层土壤盐分波动小;监测层在总合盐量上比未灌水处理前低,但所有微成水处理的都比淡水对照的大;膜下滴灌棉田盐分的变化主要受灌溉水和蒸散发的影响.

| Abstract: | Under the condition of same water quantity,the irrigation water is mixed with different proportion of saline groundwater(DOM at 3.56 g/L) and surface water(DOM at 0.4 g/L) to irrigate cotton field by using drip irrigation under plastic film to seek spatio-temporal change of soil salt contents in cotton field in Oasis.The research result indicates that the change of soil salt contents during cotton growth is mainly effected by soil water movement and surface vegetation cover degree.The salt contents of the s... |
