摘要
为解决常规施肥中常出现的"偏氮、增磷、缺钾"现象,探讨本地水稻栽培的最佳施肥比例、施肥量,采用"3414"方案,进行氮、磷、钾肥料不同配比的田间小区试验,从作物性状、产量、经济效益等方面,客观评价配方施肥的效益。结果表明:当N-P2O5-K2O比例为14-4-12kg/667m2(即氮磷钾比例为1:0.29:0.86)时,其经济性状指标与产量最高,并能取得最好的经济效益。
In order to solve the imbalance problem in regular fertilization,to explore a best formula fertilization method in rice production,to adopt a＂3414＂scheme,a plot experiment with different fertilizer mix was conducted and from the aspects of crop characters,yield and economic benefit,the fertilization effectiveness was analyzed.The results show that 14-4-12kg/667m2（N-P2O5-K2O）would have the best economic characters and highest yield,which can obtain the best economic benefit.
