| 摘 要： | 采用田间试验的方法研究施用硫酸钾镁肥对玉米产量的影响,结果表明:在施用氮磷肥的基础上,配施硫酸钾镁肥促进了玉米的生长发育,改善了玉米的经济性状,从而显著提高了玉米产量。与对照相比,施用硫酸钾镁肥处理产量增加7.5%~13.2%。同时,施用硫酸钾镁肥也获得了较高的经济效益,施用硫酸钾镁肥处理的利润比对照增加482~755元/hm2。

| Abstract: | The results of field trails indicated that combined application of sulphate-potassium magnesium based on the application of N and P fertilizer could improve maize growth and yield components, and significantly increase yield by 7.5% - 13.2%. Also the application of sulphate-potassium magnesium achieved better economic benefit. The profit from the application of sulphate-potassium magnesium was 482 - 755 yuan/hm^2. |
