【摘要】 新疆是严重干旱缺水地区，灌溉农业，农业用水占总用水量８０％以上，由于灌溉技术落后，浪费十分严重。因此，节约农业用水是缓解新疆干旱和水资源紧缺矛盾的有效途径。本文通过用负压计测定土壤水势，了解土壤水分动态变化，并对冬麦进行适时适量灌溉预报，达到显著的节水增产效果，是一项投资少、操作简单、节水增产幅度大的节水技术，为干旱地区的节水农业开辟了一条新途径更多还原

【Abstract】 injiang is a serious water lacking area, the water used in agriculture make up 80% of the total amount of water supply in Xinjiang.Water is seriously wasted due to the poor irrigation techniques. So saving the water in agriculture is an effective way to mitigate the contradiction between drought and water lack.This paper determined the soil moisture tension by using the tension meter,found out the variation of soil moisture trends,and made the irrigation scheduling experiment,it got the obvious results of water saving and output increase,which is an easy and low-invested water saving technique.更多还原
