摘　　要：为赤峰地区荞麦生产中保水剂的推广应用提供理论依据,研究了保水剂配施不同用量的常规肥料对荞麦产量的影响。结果表明,与常规施肥相比,15kg/hm2保水剂配施常规肥荞麦增产明显,其中以保水剂配施75%~100%常规肥增产效果明显,可增产286.02~778.04kg/hm2,增加纯收益851.31~2 094.12元/hm2;保水剂配施常规肥料对产量构成的影响主要表现为增加单株粒数。The effects of water-retaining agent＋conventional application with different application amount on buckwheat yield to provide the theoretical basis for popularization and application of waterretaining agents in buckwheat production in Chifeng City.Results：The yield of buckwheat applying with15kg/hm2 of water retaining agent＋conventional application increases significantly compared with the conventional application.The increased yield and increased pure benefit of buckwheat applying with water retaining agent 75%~100% conventional application amount are 286.02~778.04kg/hm2 and 851.31~2 094.12Yuan/hm2 higher than without applying water retaining agent respectively.Applying water retaining agent＋ conventional application can increase yield of buckwheat by increasing grain number per buckwheat plant.
