通过室内培养试验研究了玉米秸秆在暗棕壤和水稻土中分解期间全土及不同结合态胡敏酸、富里酸数量的动态变化。

In a laboratory incubation experiment, timing change in amount of humic acid(HA) and fulvic acid(FA) was studied in dark-brown soil and paddy soil during corn stalk decomposition.

长期施用有机肥能提高胡敏酸的含量，施用无机化肥可提高富里酸降低胡敏酸的含量。

Application organic fertilizer for long time can improve the content of humus, and inorganic fertilizer can enhance the content of Fulvic acid, decrease the content of humic acid.
