摘要

采用试验与示范相结合，对汇集雨水补灌农技措施进行了系统研究。结果表明：在干旱少雨，蒸发量大，气候冷凉的定西地区，实行地膜和秸秆覆盖加滴灌的农技措施，能有效减少土壤水分蒸发，增加作物生长需要的有效积温；实行垄沟种植，发展间套，进行雨水有限补灌，能充分发挥雨水资源的生态经济效益。

Abstract

Using methods of experiment and demonstration

the agronomy techniques for rainwater irrigation are studied.The results showed that the agronomy techniques with mulching and drip irrigation could reduce the water evaporation and increase the temperature that the crop need in semi-arid area. The ecological and economic efficiency of limited rainwater can be brought into play by the techniques such as furrow hill cultivation and multiple cultivation by using rainwater as supplementary irrigation resource.
