| Abstract: | The paper was theorteically based on the nutritive ekement equilibriun of soil and common jujube and decided the mathematica moedl of proper fertilizer ratio and use of fertilizer in quantitative yield.Through the L 9(3 3) orthogonal experiment,in theory based on the payment ratio of productive eldment,the aauthors analyzed the amount required of fertilizer in quantitative yield and balanced fertilization affeding on the common jujube yield and efficiency of water application,discussed the marginal yield and economic effect of balance fertilization the mountainous non-irrigated land Chinese date garden,supplied mathemtical computation model,dressing mathod and effective condition of proper fertilization in econmy using the native common jujube garden of mountainous nonirrgated land. |
