Title: Influence of Irrigation and Fertilization on Grain Yield of Irrigation-land Winter Wheat
Abstract: 174 samples were investigated and effects of irrigation and fertilization to yield were analyzed in south of Shanxi province in 2012.The result showed: The yield of the irrigation-land winter wheat was high in the region.The average yield was 5 836.7 kg/hm2 and productive potentialities great.When the frequency of irrigation from 1.9 times increased to 2.3,the grain yield of winter wheat increased.The fertilization condition was unbalanced in the region,the application of N fertilizer is high but P fertilizer insufficient.In the year of adequate rainfall,when the N fertilizer application was about 180 kg/hm2and P fertilizer about 100 kg/hm2,the grain yield of winter wheat was the highest.Therefore,increasing the frequency of irrigation,suitable application of fertilizers and increasing P nutrient inputs properly is of significant importance to improve the grain yield of irrigation-land winter wheat yield.
