| 摘 要： | 秋浇是新疆阿拉尔灌区秋后淋盐、春季保墒的一种特殊的灌溉制度,它涉及水资源充分利用、控制地下水位防止土壤次生盐碱化、盐胁迫下作物生长等问题。通过研究土壤含盐量、土壤含水率及盐分对棉花的胁迫与秋浇定额之间的关系,得出适合于新疆阿拉尔灌区的秋浇灌溉定额为3 500 m3/hm2。

| Abstract: | Autumn irrigation is a particular irrigation system designed to wash soil salt into deeper layers after autumn and retain higher soil moisture in spring in the Alar Irrigation District of Xinjiang autonomous region.It involves several problems,such as fully utilization of water resources,groundwater level control to prevent soil secondary Saline-alkalization,growth of crops under salt stress.Through experimental research on the relations among soil salinity,soil moisture,effect of salt stress on growth of cotton and autumn irrigation norm,feasible autumn irrigation norm for the Alar Irrigation District of Xinjiang is determined,which is 3 500 m3/hm2. |
