摘　　要：通过苦荞麦的施肥试验,研究苦荞麦生长发育过程及其水分供需特点。结果表明,施肥对于苦荞麦的生长发育以及产量的形成有着显著的影响,能够明显提高其籽粒产量和水分利用效率;降水基本满足苦荞麦生育期的水分需求,在全生育期主要消耗0~80 cm土壤水分。The experiment of the different fertilizer of tartary buckwheat studies the growth process and characteristics of supply and demand of water of tartary buckwheat. The results show that the fertilization has a significant effect in the growth development and yield formation of the tartary buckwheat. The yield and water use efficiency of tartary buckwheat can be improved. The natural precipitation basically meets the water demand of buckwheat growth period. Soil moisture in depth 0-80 cm is the main consumption in the whole growth period of tartary buckwheat.
