摘　　要：通过2008年4—10月对民勤地区玉米注水播种的试验,测定了注水播种技术条件下作物的耗水规律及耗水量,分析配套施用保水剂对土壤水分的影响。研究结果表明,在民勤地区,采用免储水灌注水播种技术,配合使用保水剂,能使证玉米增产15%以上,减免冬季或春季储水灌溉水量1 800~2 700 m3/hm2,水分利用效率提高30%以上;施用保水剂具有减少作物耗水量的作用;保水剂施用量越大,效果越明显。Through the experiment on sowing with water of absolved water-storing irrigation in Minqin Region during the month of 4 to 10 in 2008.The water consumption law and water consumption were tested under water-storing irrigation conditions.The impact on soil moisture of matching application water-holding agent was analyzed.The results show that in Minqin Areas,use sowing with water technology of absolved water-storing irrigation and matching application water-holding agent would permit more than 15% of corn production,reduction irrigation water 1 800 to 2 700 m3/hm2 in winter or spring,improve water use efficiency 30% or more.Use water-holding agent can reduce water consumption and use it greater the more obvious effects.
