Abstract:N trace experiments show that organic and inorganic fertilizer applied together promotes organic N mineralization and absorption. Base fertilizer is mainly for nutrition organsand spring fertilizer for reproduction organs. Organic and inorganic fertilizer applied to-gether obtained the highest production efficiency of total N. Total P amount in wheat plant isslightly bigber than that of inorganic N applied ouly, but P distribution in nutrition organswas slightly lower than that of inorgainc N applied only. Organic and inorganic fertilizer ap-plied together, not only promoted the production but also increased fertility of soil , so it isan important measure for wheat to obtain high production continuously.
