摘要： 利用长期定位试验并结合裂区试验,研究长期不同施肥方式对淡涂泥土水稻产量、基础地力变化的影响。结果表明,连续不施肥显著降低了水稻产量,不施肥处理(CK)水稻产量水平逐年下降,在该试验周期内降幅达34.4%。长期施用不同肥料均有利于水稻稳产或增产,连续纯施化肥(NPK)、测土配方纯施化肥(N1PK)和测土配方有机无机混合施肥(N1PKS)处理的水稻产量比不施肥处理(CK)分别提高74.2%、89.0%和97.5%,达到极显著差异。长期施用不同肥料均有利于土壤基础地力的提升,其中测土配方有机无机混合施肥对于土壤改善效果最为显著,在该试验周期内,与长期不施肥处理相比,NPK处理、NIPK处理、N1PKS处理土壤基础地力产量分别提高了45.6%、60.8%和69.1%。各施肥处理土壤基础地力贡献率无明显差异。

Abstract: A long-term fertilization experiment coupled with split plot experiment was carried out to explore the effect of different modes of long-term fertilization on rice yield and basic soil productivity in coastal paddy. The results showed that long-term non-fertilization application decreased rice yield significantly, with the experiment going, rice yield in non-fertilization application (CK) decreased year by year and the decreasing range was 34.4% during the test period. Long- term chemical fertilization application (NPK), long- term chemical soil testing fertilization application (N1PK) and long- term chemical soil testing fertilization application combined with organic fertilizer (N1PKS) increased rice yield. Compared with CK, the rice yield under NPK, N1PK and N1PKS increased by 74.2% , 89.0% and 97.5% , the differences were all highly significant. NPK, N1PK and N1PKS improved basic soil productivity (BSP), especially N1PKS. During the test period, NPK, N1PK and N1PKS increased BSP yield by 45.6%, 60.8% and 69.1%, as compared with CK. There was no significant difference in the contribution rates of basic soil productivity between NPK, N1PK and N1PKS.
