目的:为了探讨不同施肥模式对水稻产量及土壤肥力的影响,找到不同肥力水平土壤的最佳施肥模式.方法:本试验在浏阳市荷花镇(低产田)、达浒镇(高产田),比较不施肥(T1)、常规施肥(T2)、40％有机肥(T3)和纯化肥(T4)的水稻产量和土壤肥力变化.结果:施肥处理均能显著提高荷花、达浒两地水稻产量.T2和T3处理能通过增加水稻有效穗数和每穗粒数使水稻产量显著增加.在荷花,T4处理比T1 ～ T3处理分别增产49.8％、2.28％、0.08％;在达浒,T3处理比T1、T2、T4处理分别增产34.15％、12.43％、8.84％.两地土壤养分含量、肥力综合评价值均表现出T3处理显著高于其他处理,且逐年增加.结论:不施肥会降低水稻产量和土...

Objective of this study was to explore the effects of different fertilization patterns on rice yield and soil fertility, and found the best fertilization patterns on paddy field with different fertility levels. In this study, rice yield and soil fertility changes of non-fertilization(T1), conventional fertilization(T2), 40% organic fertilizer(T3) and pure fertilizer(T4) were compared in Hehua village(low-yielding field) and Dahu village(high-yielding field). Results showed that fertilization treatment significantly improved the yield of rice in Hehua and Dahu. Rice yield of T2 and T3 treatment...
