Abstract:

2000mg/kg and 1250mg/kg of potassium humate liquid were applied on soybean in blooming stage , and inblooming and pod setting stage respectively in this test .The results showed that the potassium humate had a significantinfluence to the plant characteristics and yields of soybean .The average soybean yield reached 3699.9kg/hm2 , increased14.06 % than control .
