为了探明长期施肥对红壤稻田土壤性质及晚稻产量与品质的影响,以期为南方红壤稻田优质高产协同提升目标下的土壤高效培肥提供理论依据。依托始于1982年的长期定位试验,考察了有机肥（M）、化肥氮磷钾配施有机肥（NPKM）、化肥氮磷钾（NPK）、化肥氮钾配施有机肥（NKM）、化肥氮磷配施有机肥（NPM）、化肥磷钾配施有机肥（PKM）、不施肥（NF）对稻田土壤养分含量、酶活性、阳离子交换能力、籽粒产量构成与稻米品质的影响。结果表明:与NF处理相比,各施肥处理均可不同程度提高土壤有机碳及氮磷钾含量,增强脲酶、酸性磷酸酶、蔗糖酶和纤维素酶活性,提升土壤阳离子交换能力,进而提高水稻籽粒产量;进一...

To explore the effects of long-term fertilization on soil property and grain yield and quality of late rice,and provide the theoretical basis for promoting the soil fertility under the goals of improving both grain yield and quality in reddish paddy field of Southern China,the long-term experiment initiated in 1982 was conducted to investigate the effects of different fertilization regimes (manure: M; chemical NPK+ manure: NPKM; chemical NPK: NPK; chemical NK+ manure: NKM; chemical NP+ manure: NPM; chemical PK+ manure: PKM; no fertilization: NF) on nutrient contents,enzyme activities,cation ex...
