Making fertilization scheme is an effective way to improve the fertilization effect, reduce the cost of fertilization and increase the production and income. The shadow price and the analysis of sensibility can supply effective help for making and adjusting the fertilization. The paper explains the application of fertilizer shadow price in adjusting the fertilization schefne through the example. Moreover the economic significance of the fertilizer shadow price has been analyzed. The way of applying analysis of sensilility effectively to adjust the fertilization scheme from some aspects, such as the limitation coefficient, price coefficient, value coefficient and so on, also have been analyzed by the example. Thus the results of the present study can provide scientific policy- making basis for scientific farming, saving cost, increasing production and income.
