摘要
进行硫酸钾镁肥在马铃薯上的肥效试验研究,结果表明:磷酸二铵450 kg/hm2+尿素75 kg/hm2+硫酸钾镁肥300 kg/hm2的处理马铃薯产量最高,磷酸二铵450 kg/hm2+尿素75 kg/hm2+硫酸钾镁肥225 kg/hm2的处理施肥投入成本较低,经济效益最佳。
Fertilizer efficiency test of potassium anct magnesium sulfate on potato was carried on.The results showed that the treatment that diammonium phosphate 450 kg/hm2＋urea 75 kg/hm2＋potassium and magnesium sulfate 300 kg/hm2, could get the highest yield ;while the application amount of diammonium phosphate was 450 kg/hm2,urea was 75 kg/hm2,potassium and magnesium sulfate was 225 kg/hm2,the treatment got low cost and high economic benefit.
