Example Embodiment
[0038] Example 1B type nursery agent
[0039] 1. Acidification of cinder: First, dry the raw cinder and pulverize it to 10-15 mesh. Spread the raw cinder powder flat on the ground. For each layer of cinder powder, sprinkle a layer of sulfuric acid water and evenly spread it on the cinder powder. Above, for every 100 kg of brown coal slag powder, add 20 kg of water with a mass concentration of 30% sulfuric acid, and the thickness of each layer of slag powder is 4 inches; when it reaches 3 feet thick, start stirring, and after mixing, seal it with plastic cloth; The maturation period is 7 days. Finally, spread the pile, open the agglomerate, and stir again to serve as a spare raw material;
[0040] 2. Preparation of nitrohumic acid: the preparation process is divided into three steps: raw material processing, nitrification and maturation
[0041] (1) Raw material processing: Using lignite as the raw material, the water content of the lignite is naturally air-dried to a water content o...
