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。
[ Objective ] Maximum economic benefit of fertilization modes was studied. [ Method] Based on the data of long-term location experi-ment 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 re-search could provide guidance for fertilizer application in rice.
