摘要
对吉林省榆树市白浆土种植大豆施用钾肥的适宜用量进行了研究。结果表明:小区试验钾的适宜用量为K2O40.05～60kg/hm2。示范试验施用K2O40.05kg/hm2,大豆平均增产125.25kg/hm2,平均增产9.4%,平均增收306元/hm2。
The suitable amounts of potassium fertilizer for soybean were studied in albic soil in Yushu, Jilin. The result indicated that the suitable application amount of potassium in plot experiment was K2O 40.05 - 60 kg/hm^2. The demonstration experiments applied K2O 0.05 kg/hm^2, the soybean production increased 125.25 kg/hm^2, about 9.4% in average, additional incomes were 306 yuan/hm^2.
