摘要
半干旱黄土丘陵区水资源相对贫乏,而山区果园多采用漫灌方式进行灌溉,对水资源造成了很大程度的浪费.通过对宁夏西吉县聂家河流域果树小管出流补灌试验,分析和探讨了该地区主要果树的土壤水分和耗水规律,在此基础上制订了几种果树小管出流补灌制度,为该地区果园水分合理管理提供依据,也为当地水资源合理利用提供参考.
Water resources are relatively deficient in semi-arid loess hill area.However,the orchards there are usually irrigated by using the flood irrigation so as to waste water resources to a great extent.Through the test of supplementary irrigation by using small pipe flow,soil moisture and water consumption rule for local fruit trees were analyzed.On the basis of test results,the system for supplementary irrigation by using small pipe flow was worked out,which provided the basis for the rational management of local orchard water usage,as well as the reference for the rational utilization of local water resources.
