摘要： 通过连续4年定位试验，研究了不同施肥对保护地土壤肥力及作物产量的影响，试验结果表明：单施有机肥，耕层（0~20cm）土壤有机质、全氮、全磷含量年均分别增加1.032、0.059、0.033，有机肥和化肥配施年均增加0.593、0.031、0.023，单施化肥年均增加0.224、0.012、0.007，同时亚表层土壤（20~40cm）有机质、全氮、全磷的含量也有不同程度的增加；另外，在该项试验条件下，不同施肥对产量的影响差异不显著。

Abstract: The influence of different fertilization impact on soil fertility and yield of crop fruits were studied for four years. Results indicated that in using organic fertilizer, contents of organic matters, total nitrogen, total phosphor in the soil of arable layer (0~20cm) increased by 1.032%、0.059% and 0.033%; and that in using organic fertilizer and chemical fertilizer increased by 0.593%、0.031% and 0.023%; and that in using chemical fertilizer increased by 0.224%、0.012% and 0.007%. The difference of the influence of different fertilization impact on yield of crop fruits were not prominence.
