| 摘 要： | 为探讨新疆棉田地下滴灌方式地下滴灌下土壤水盐运移的规律,在棉花不同生育期运用烘干法和电导法,从水平方向和垂直方向测定棉田距离滴灌带不同距离的土壤含水量和土壤盐分,结果表明地下滴灌条件下棉花整个生育期土壤含水量的运移规律为:0~35 cm各土层苗期与蕾期较低,盛花期较高,吐絮期又较低,35~55 cm各土层在苗期与蕾期较低,花铃期至吐絮期均较高;土壤盐分含量的变化与土壤含水量的变化刚好相反。

| Abstract: | To explore the law of water and salt movement in subsurface drip irrigation of cotton field in Xinjiang,using drying and conductivity soil moisture and soil salt from the horizontal and vertical directions in different stages of cotton were measured.The results showed the law of soil moisture throughout the growing period of cotton was: soil moisture in 0-35cm was lower in seeding and budding stage,and higher in flowering stage,but lower in opening stage,while in 35-55cm soil water was lower in seedling and budding stage,and higher from flowering stage to opening stage;the changing of soil salt was just opposite to soil water. |
