| 摘 要： | 试验采用2000mg/kg,1250mg/kg腐植酸钾肥液在大豆盛花期喷施一次和盛花期、结荚期各喷施一次。结果表明，腐植酸钾对大豆的植株性状和产量性状均有显著的促进作用，产量亦显著提高。以2000mg/kg肥液在大豆盛花期和结荚期各喷施一次，综合经济效益最佳，平均产量达3699.9kg/hm^2，比对照增产14.06%，投入产出效率为11.45元／元。

| Abstract: | mg/kg and 1250mg/kg of potassium humate liquid were applied on soybean in blooming stage, and in blooming and pod setting stage respectively in this test. The results showed that the potassium humate had a significant influence to the plant characteristics and yields of soybean. The average soybean yield reached 3699.9kg/hm 2, increased 14.06% than control. |
