摘　　要：采用保水剂对春小麦拌种,制定不同灌溉制度,开展生育期耗水规律及产量试验研究。结果表明,春小麦利用保水剂拌种包衣措施与常规播种相比,可提高土壤的持水性能、减少土壤水分蒸发、提高水分利用率、促进植物生长发育。全生育期土壤含水率提高0.15%~2.75%,增产150~225 kg/hm2,单方水效益提高0.03~0.06 kg/m3,达到节水增产的目的。Basing on the experiment of different irrigation schedules that was carried out on spring wheat dressed with water retaining agent,we studied the yield and water consumption pattern of growth period.The results showed that applying water retaining agent had the benefits of improving soil water-holding capacity,reducing soil water evaporation,improving water use efficiency,and promoting plant growth and development.Using water retaining agent made production by 150-225 kg/hm2,beneficits of pre-stere water by 0.03-0.06 kg/m3 and soil moisture content in whole growth period increase by 0.15%-2.75%.The purpose of water-saving and production increasing were gained.
