摘  要:
为了提升和改善水稻田土壤质量、减少农民投入,本试验在等量腐熟秸秆还田的基础上,减量施用氮、磷、钾肥料的方法,研究了油菜秸秆还田、减量施用氮磷钾元素对稻谷产量和稻田经济效益的影响。一年的研究结果表明:减量10%常规施肥(N 6.3kg,P_2O_5 5.4kg,K_2O 6.75kg)+腐熟秸秆还田不影响稻草生物量,各项经济性状最优,稻谷的产量最高,产量达580.27kg/667m~2,增产达极显著差异,增产率为18.53%,产投比最高,达2.58,纯收益增加272.14元/667m~2。

摘  要:
In order to enhance and improve the quality of paddy soils,reduce farmers' inputs,this experiment on the basis of equal rotted straw,reduced fertilization of nitrogen,phosphorus and potassium fertilizer method of rape straw returning,reduction of nitrogen,phosphoru and potassium application element effects on Rice Yield in paddy field and economic benefits,and a year of research results show that: Rduction of 10% in conventional fertilization(N6.3kg,5.4kg of P_2O_5 and K_2O 6.75kg) + rotten straw does not affect the straw biomass,the economic traits of the best,rice yield is highest. The yield of 580.27kg/667m2,yield of significant differences,an increase of rate of 18.53%,investment ratio is the highest,reaching 258,net income increased 272.14 yuan/667m2.
