国产硫酸钾镁肥对花生产量、品质与效益的影响

Effects on Yield Quality and Benefit of Applying Homemade Sulphate-Potassium Magnesium Fertilizer to Peanut

通过田间试验,研究在施用氮磷肥基础上,配施硫酸钾镁肥对花生产量、品质与效益的影响。试验结果表明,施用硫酸钾镁肥有利于提高花生产量,改善品质,增加经济效益。配施硫酸钾镁与配施硫酸钾、氯化钾相比,产量分别提高12.7%和11.7%,经济效益分别增加1022元/hm2和485元/hm2。

The effects on yield, quality and benefit of applying sulphate-potassium magnesium fertilizer to peanut through field experiments based on applying nitrogenous fertilizer and phosphate fertilizer. The results showed that applying sulphate-potassium fertilizer can raise yield, improve quality and increase economic benefit on the supplied soil in which the content of quick acting potassium is 31.0 mg/kg, the content of fast-acting magnesium is 37.5 mg/ kg, the content of available sulphur is 18.7 mg/kg. Compared with applying potassium sulfate and potassium chloride, the yield of peanut applied sulphate-potassium magnesium enhanced 12.7% and 11.7%, respectively the economic benefit of peanut increased 1022 yuans and 485 yuans per hectare as well.
