为了减少小麦灌溉用水量,提高土壤水的利用效率,2005-2007年,开展了节水灌溉对小麦生长发育和产量影响的研究。结果表明:根据冬春季降雨的具体情况,春季可适当节约1～2水,对小麦效益影响不大,同时每667m2节约水资源40～80m3,并且常规灌溉田间耗水量最大,达327m3,其中土壤水只占7%,节水灌溉田间耗水量为304m3,其中土壤水占16.4%,土壤水的利用率提高了1倍以上。
In order to reduce the irrigation water requirement of wheat and improve the utilization efficiency of soil water, a study on the effect of water-saving irrigation on the growth and yield of wheat was conducted from 2005 to 2007. The results showed that according to the specific conditions of winter and spring rains, the spring could save 1 ~ 2 water properly, and had little effect on the benefit of wheat. At the same time, water resources of 40 ~ 80m3 were saved per 667m2, and the water consumption of conventional irrigation was the largest, Water accounts for only 7%, water saving irrigation field water consumption of 304m3, of which 16.4% of soil water, soil water utilization increased more than 1 times.
