| 摘 要： | 为探讨新疆棉田地下滴灌条件下土壤水盐运移的规律,在棉花各个生育阶段运用TDR和取样从水平方向和垂直方向测定棉田距滴灌带不同位置的土壤水分和盐分,研究分析后认为地下滴灌条件下棉花整个生育期土壤中盐分运移规律为:苗期较高,花铃期较低,吐絮期又较高。盐分经过长时间的水平和垂直运移,水平方向在距滴灌带较远的地方含盐量较高,最后在滴灌带中间位置积聚;垂直方向在耕作层的盐分含量有所降低,耕作层处于脱盐过程,盐分主要向深层运移,在80 cm以下的土层处于积盐过程。

| Abstract: | To research the regulation of soil water-salt transport under subsurface drip irrigation(SDI) in cotton field in Xinjiang.By the way of using tension meter,TDR and sampling measured 1m depth layer soil moisture rate and electric conductivity,which in each section of cotton procreate,irrigation former or after and different distance away from drip tube viewed: In the cotton all procreate period,the soil salt is higher in seedlings period,lower in boll period, and become higher in flower period.At last,the salt gather in the area between drip tubes,salinity of cultivation layer become lower,it moves to deep layer,and gather in the area under 80 cm. |
