Embodiment 1
[0021] A humic acid biofertilizer fermented by microorganisms comprises 100 parts by weight of humic acid fermentation liquid and 15 parts of urea.
[0022] The preparation method of the humic acid fermentation liquid: first prepare 100 parts of humic acid raw materials by weight, 10 parts of soybean powder, 10 parts of fish meal, 10 parts of glucose, 0.1 part of inorganic salt, and 500 parts of water according to conventional methods to prepare culture medium , wherein the inorganic salt is a compound of one or more of potassium dihydrogen phosphate, manganese sulfate, and calcium chloride; then sterilize the medium with steam, sterilize at 121°C for 20 minutes, and then replace the air to maintain pressure. At the same time, cool the culture medium to the optimum culture temperature; inoculate the microbial compound bacterial agent on the culture medium according to the inoculation amount of 3%, and carry out aerobic fermentation first. The fermentation condition is that the ...
