摘    要:水旱轮作田间定位试验条件下研究了连续4年(20052008)不同施肥模式对双季稻产量、养分吸收及经济效益的影响。结果表明,氮磷钾肥配施能显著提高水稻产量,长期有机无机肥配施增产效果明显。定位4年后,有机无机肥配施处理早稻和晚稻平均产量分别比未施肥处理增产135%和130%。随着产量的增加,稻草与稻谷中氮、磷和钾养分吸收量呈增大的趋势,表明水稻植株养分吸收量与稻谷产量呈显著正相关。不同施肥模式显著影响水稻稻草、稻谷中的氮、磷、钾养分含量。氮磷钾肥配施处理,特别是有机无机肥配施处理稻谷的养分吸收量最高,在土壤中的氮、磷盈余也最少。肥料配施虽增加了支出,但提高了经济产出,其纯收益相对较高,以有机无机肥配施处理的纯收益最高。双季稻生产实践中,有机无机肥配施模式值得推荐且需合理增施磷、钾肥。

关 键 词:双季稻   施肥   产量   养分吸收   经济效益

Abstract:Effect of fertilization on double-season rice yield,nutrient uptake and economic benefit under paddy-upland rotation was studied through a long-term field experiment during 2005 to 2008.The result showed that grain yields were significantly increased by combined application of nitrogen(N),phosphorus(P) and potassium(K) fertilizers.The effect of chemical fertilizers plus organic fertilizer[1/2(M+F)]on grain yield became more significant as the planting seasons continued.The grain yield of early and late rice...
Keywords:double-season rice  fertilization  yield  nutrient uptake  economic benefit
