本文通过对麦田的土壤水分监测结果,分析了麦田水分供求状况。说明播种期墒情好、全生育期2米土层的相对有效土壤贮水量维持在50%以上,是取得好收成的重要条件。根据旱地小麦土壤水分动态对在有限的水资源条件下,从灌溉时间、灌溉次数、灌溉量等方面探讨了提高水分利用效率问题。 This paper analyzed the moisture supply and demand in wheat field by monitoring soil moisture in wheat field. The results showed that soil moisture at sowing period was good, and the relative effective soil water storage of 2 m soil layer during the whole growth period was maintained above 50%, which was an important condition for good harvest. According to the soil moisture dynamics of dryland wheat, the issue of improving water use efficiency was discussed under the conditions of limited water resources, such as irrigation time, irrigation times and irrigation amount.
