| 摘 要： | 通过田间试验,在施用氮、磷肥基础上,研究了施用硫酸钾镁肥对萝卜产量和经济效益的影响.结果表明,施用硫酸钾镁肥能显著提高萝卜叶片中叶绿素含量;与不施钾处理相比,生物产量增加6.9%,商品菜产量提高11.0%;每667 m2增加效益49.46元;其产量的增加和效益的提高均高于配施氯化钾和硫酸钾处理,亦略高于配施等量养分K、S、Mg单质肥料处理.

| Abstract: | Effects of sulphate-potassium magnesium on yield and economic benefit of radish was studied by field experiment based on N and P application.The results showed that sulphate-potassium magnesium application could significantly increase the content of chlorophyll in leaves of radish.Sulphate-potassium magnesium application increased vegetative yield and radish yield by 6.9% and 11.0%,respectively,raised economic by 49.46 yuan/667 m2 comparing with no potassium fertilizer.The yield and economic benefit of sulphate-potassium magnesium application was higher than that of other potassium fertilizer application. |
