Abstract: Through the fertilizer location experiment of one-year wheat-corn rotation system on Chao soil for seven years,the utilized coefficient of fertilizer and the nutrient requirement quatity of crops were obtained. The integrated application of inorganic nitrogen and phosphorus on the basis of manure is one of the best agrotechnique both for getting stable-high yield and economic efficiency of crops and for improving the soil fertility. The optimum application quatity of nitrogen and phosphorus is 240kg/m2 and 60kg/m2 each year, respectively.

Key words: Wheat, Corn, Fertilizer location experiment, Utilized coefficient of fertilizer
