Donggang Hui-yu humic acid fertilizer company uses fermented peat as raw material to produce humic acid compound fertilizer, and in 2003 through Donggang Agricultural Technology Promotion Center in several townships to carry out demonstration promotion experiment. The results showed that HA1 was suitable for cabbage, yield increased by 19.52%, Vc content increased by 26.81%, reducing sugar increased by 11.21% and nitrate decreased by 6.67%. The humic acid compound fertilizer 2 (HA2) is suitable for the increase of eggplant, cucumber crops, cucumber and melon by 13.62% and 40.74%, Vc content of melon by 48.89%, reducing sugar by 2.03% and nitrate by 8.02% . Demonstration tests show that humic acid compound fertilizer yield, improve quality and reduce nitrate significant role, is the production of green food-friendly fertilizer.
