通过三年多点田间试验，研究了有机、无机肥料配施对豫西旱区小麦的增产效果，建立了该区高中低三个地力水平下的施肥模型，提出了小麦丰产的适宜肥料用量。同时对不同投肥结构和投肥水平下小麦的水分利用效率进行了探讨，并讨论了不同降雨年份小麦在降雨利用方面的差异。 Through more than three years of field experiments, the effect of organic and inorganic fertilizers on wheat yield in arid areas of western Henan was studied. The fertilization models at high, medium and low fertility levels in the area were established, and the appropriate amount of fertilizers for wheat was put forward. At the same time, the water use efficiency of wheat under different fertilization structures and fertilization levels was discussed, and the differences in rainfall utilization in different rainfall years were discussed.
