摘    要:为探讨秸秆还田对土壤肥力的影响,该文以18年的定位试验为基础,通过对直接施用秸秆、有机肥以及化肥、有机肥配施等6个处理小区的土壤进行采样,分析了秸秆还田同有机肥培肥方式对土壤理化性质、养分状况与作物产量等方面的影响,着重探讨了秸秆直接还田同传统的施用腐熟有机肥对土壤的培肥效果差异.结果表明直接施用作物秸秆同施用腐熟有机肥对土壤的培肥效果基本相同,均对土壤理化性质有很大的改善,同时可提高作物的产量,因此秸秆直接还田基本可以代替施用腐熟有机肥培肥土壤.

关 键 词:秸秆还田  腐熟有机肥  培肥  水稻土

Abstract:To study effects of straw-returning on soil fertility, the six treatments (straw-returning, decomposed manure and combined organic manure and chemical fertilizer, etc.) were conducted based on 18-year location experiment in Ningxiang. In this experiment the effects of straw-returning and decomposed manure treatments on soil physical and chemical properties, nutrient status and crop yields, especially the difference of fertilizing effect between straw-returning and traditional mode on decomposed manure application were analyzed. The results show that the effects of straw-returning and decomposed manure on fertilizing effect of soil are similar. The straw-returning and decomposed manure treatments can improve the soil physical and chemical properties and increase the crop yields. So the decomposed manure can be superseded by the straw-returning treatment.
Keywords:straw-returning  decomposed manure  fertility betterment  paddy soil
