| 摘 要： | 稻田土壤中养分的平衡主要取决于养分的输入与输出,其又主要受肥料的输入与植物所带走的养分所制约。不同的肥料品种、不同的施肥时期都影响养分在土壤中的吸收、转化与淋失,从而影响养分的输入与输出。稻田土壤生态系统中养分循环的研究已有很多报道。主要是不同耕作制度、不同施肥水平下,各输入输出因子的研究以及对土壤肥

| Abstract: | A field experiment was made for examining the effect of different fertilizers on the balance of nutrients and crop yields. It was showed that N and p were surplus in the treatment of pig manure application, but deficient in that of chemical fertilizer application, and K was deficient in the both. Crop yield was increased by using chemical fertilizer and orgaic manure. 4 years field experiment revealed that organic manure could increase the storage of natrients in soils and improve soil fertility and crop yield. |
