摘要：

Through the orthogonal test, the effects of two kinds of soil amendment fertilizers on yield and water use efficiency of spring maize were studied. Results indicate that the fertilizer with straw and loessial soil could keep the yield when 28.6% of inorganic fertilizer was reduced, as the research was done under the influence of the different spring maize varieties, different fertilizer amounts and different irrigation amounts. At the same time, the water use efficiency and precipitation use efficiency were increased. Compared with conventional urea, the fertilizer with straw could make the soil evaporation less and improve the storage capacity of soil water in 0-20 cm effectively in seedling and jointing stage. The study could provide a theoretical basis for popularize of soil amendment fertilizer with straws.
