Example Embodiment
[0020] Example 1
[0021] 1. At 3m 3 Keep 1,000 kg of "beneficial microorganism fermentation broth" in the fermenter, and raise the temperature of the fermenter to 80°C;
[0022] 2. Weigh 100 kg of borax and add it to the fermentation tank, keep the temperature of the fermentation tank at 80-100℃, and chelate for 20 minutes;
[0023] 3. Weigh 80 kg of zinc sulfate (seven water or one water), add it to the fermenter, keep the temperature of the fermenter at 80-100℃, and chelate for 10 minutes;
[0024] 4. Adjust the PH value of the liquid in the fermentation tank to 5.5-6.5, weigh 200 kg of urea, 200 kg of potassium dihydrogen phosphate, and 220 kg of water-soluble potassium sulfate, add them to the fermentation tank, and keep the temperature of the fermentation tank at 80-100°C. Chelate for 30 minutes;
[0025] The product obtained through the above four-step chelation is the "liquid fertilizer (containing trace element type)" described in the claims. Each drop of the product contains...
