Embodiment 1
[0033] A preparation method of compound microbial fertilizer, comprising the steps of,
[0034] Step (1), yeast pre-fermentation;
[0035] Collect crop stalks and crush them, add starch, humic acid, peptone, potassium dihydrogen phosphate, sodium citrate, ammonium nitrate, magnesium sulfate, stir well, stir under ultraviolet light for sterilization, and then add appropriate amount Adjust the water content of the material to 50% with water to obtain the pre-fermented material; then inoculate yeast, control the temperature of the material at 25°C during the fermentation process, and maintain it for 10 days;
[0036] Wherein, the weight ratio of the straw, starch, humic acid, peptone, potassium dihydrogen phosphate, sodium citrate, ammonium nitrate, and magnesium sulfate is 100:1:5:0.1:0.01:0.02:0.02:0.01;
