【Abstract】 Two-factor-split experiment was conducted to study the effects of variety and fertilizer on the yield and the utilization of water and fertilizer of tartary buckwheat(Fagopyrum tartaricum).The results show that the yield of “Heifeng”is higher than that of “Qianwei”,and the yield of these two varieties is significant higher than that of “Shouyanggray”.The yield of these three varieties is increased significantly by applying both manure and chemical fertilizers.The optimum combination for fertilizers is one part manure with one part chemical fertilizer.Fertilizer and water use efficiency of tartary buckwheat can be improved by planting the suitable variety and applying fertilizers rationally.更多还原
