在试验设计水平内受长期连续施肥的影响,枣园土壤全磷、速效磷、缓效钾及速效钾含量都有不同程度提高,建立了施肥量与土壤中的全磷、速效磷、缓效钾、速效钾关系模型.对不同土层的分析得出土壤全磷随着土层深度的增加提高的程度越低,速效磷,速效钾也是如此,缓效钾的结果相反,随着土壤深度增加,其提高的程度越大.在试验设计水平内,连续施磷钾肥能够明显提高土壤肥力,说明施入土壤的肥料已经转化为土壤中的养分,已经满足当前枣树产枣的需求,可以间断性施肥,保持土壤肥力,使其维持在当前水平,以减少种植枣树成本,且能保持原来的效益.

. affected by long-term continuous fertilization in the experimental design level, Zaoyuan soil total P, available P, K and available K content were improved in different degree, established the model of fertilization and soil total phosphorus, available phosphorus, available potassium, slowly available K relationship. Analysis of the different layers of the soil total phosphorus with soil depth increasing degree is low, available phosphorus, available potassium is also so, slowly available potassium was on the contrary, with the increase of soil depth, the greater the degree of improvement. In the experiment the design level, continuous phosphate fertilizer and potassium fertilizer can improve the soil fertility, the soil applied fertilizer has been transformed into the soil, has to meet the current needs of jujube date, can be intermittently to maintain soil fertility, fertilization, to maintain the current level, in order to reduce the cost of planting date, and can keep the the original benefit.
