摘要
[目的]研究水稻种植经济效益最高的施肥方式.[方法] 以水稻长期定位试验数据为基础,采用Saleque等介绍的方法对各种施肥制度的表观经济收益以及收益率进行评价.[结果]2NPK、NPK以及NP处理所获得的收益明显高于其他处理(P<0.05);从投资收益率来说,NP处理由肥料投资所获得的收益率最高,其次为NPK处理, 2NPK处理投资收益率较低,仅为NPK处理50%左右.因此,从经济角度讲,现行的推荐施肥方式具有最好的经济回报.[结论]该研究可为生产上水稻施肥提供指导.
Abstract
[Objective] Maximum economic benefit of fertilization modes was studied.[Method]Based on the data of long-term location experiment for rice ,Saleque and other persons' method was adopted to evaluated apparent economic benefit and return of different fertilization systems.[Result] Benefit of 2NPK,NPK and NP treatment was obvious higher than other treatments(P<0.05).Concerning rate of return on investment,benefit of NP treatment was the highest,NPK treatment was next,2NPK treatment was low.Benefit of 2NPK treatment was only 50% of NPK treatment's benefit.Therefore, the recommended fertilization method had optimum economy return from economic angle.[Conclusion]The research could provide guidance for fertilizer application in rice.
