摘要
以西红柿、黄瓜和青椒为试材,采用对比试验方法,研究了国产硫酸钾镁肥在北方蔬菜上的应用效果。结果表明,配施硫酸钾镁肥可明显提高蔬菜产量,并能在一定程度上提高蔬菜品质,施用硫酸钾镁肥虽然比施用硫酸钾和氯化钾的投入成本略高,但产投效益最好。
The paper studied the effects of local Potassium-magnesium Sulfate on vegetables in northern China. The results showed that the vegetable output had increased significantly by using local Potassium-magnesium Sulfate compared with the control. In equivalent conditions of Potassium, the Potassium-magnesium Sulfate lead more increasing effect and input-output profit than Potassium Sulfate and Potassium Chloride.
