摘要
试验采用 2 0 0 0mg/kg ,12 5 0mg/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 2 0 0 0mg/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 36 99.9kg/hm2 ,比对照增产 14 .0 6 % ,投入产出效率为 11.4 5元 /元。
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.
