| 摘 要： | 本文探讨不同肥料、施肥结构、施肥方法对土壤养分三要素平衡与累积的影响。结果表明，不同形态单位氮素投入对土壤氮素盈余影响为猪粪〉化肥〉稻草，对土壤全氮提高的影响为稻草〉化肥〉猪粪；不同形态单位磷素投入对土壤磷素盈余的影响为猪粪〉化肥〉稻草，对土壤全磷提高的影响为化肥〉猪粪〉稻草；不同形态单位钾素投入对土壤钾素盈余影响为化肥〉猪粪〉稻草，对缓解土壤钾素下降的影响为猪粪〉稻草〉化肥。

| Abstract: | This title discussed the effects of different fertilizers,fertilization configuration and fertilization methods on soil fertility,and also took some researches on the balance and cumulation of N,P,K nutrients in soil.The results showed that the effects of unit N on the surplus of N in soil were dungs of pig>fertilizers>straws,the effects on increasing the whole N in soil were straws> fertilizers>dungs of pig;the effects of unit P on the surplus of P in soil were dungs of pig,the effects on increasing the whole P in soil were fertilizers>dungs of pig>straws;the effects of unit K on the surplus of K in soil were fertilizers>dungs of pig>straws,the effects on reducing the K loss in soil were dungs of pig>straws>fertilizers. |
