Nitrogen-fixing bacteria. Various crops other than legumes, such as wheat, corn, vegetables, etc., can be applied. Can be used as base fertilizer, top dressing, or used for rooting and seed dressing. Can not be used with strong acid, strong alkali or bactericidal pesticides and fertilizers. Can not be applied at the same time as a large amount of nitrogen fertilizer, at least 10 days apart. However, when combined with organic fertilizer and phosphorus and potassium fertilizer, it is beneficial to promote the activity of nitrogen-fixing bacteria. Use 0.5-1 kg per acre, first mix the crop seeds with water, sprinkle with the bacteria and mix well. It is best to mix with bran, crushed corn and phosphate fertilizer to form a nutrient solution, then pour the seeds into the mixture. When topdressing, it can be mixed with soil ditch and applied to the plant or near the plant.
Antibiotics. It can reduce the rotten roots of crops, increase the emergence rate, and promote growth and promote early maturity. It also has a certain inhibitory effect on some underground pests. Wheat and beans can be mixed with mushroom powder. First, spray the seeds with water, use 30-50 grams of bacteria powder per acre, mix well; or mix 5-10 parts of the powder, mix 10 parts of cake powder, 100-300 parts of fat soil in the cake. As a base fertilizer or top dressing, use 100-250 kg per acre, and mix it with superphosphate to make a good effect. Can be mixed with pesticides, but not with fungicides.
Phosphate agent. Generally divided into two types: one is an organophosphorus bacteria, which converts the hard-to-use organic phosphorus into a form that can be used by plants by means of an enzyme produced in the life of bacteria; the other is an inorganic phosphorus bacteria produced by it. Acid to enhance the dissolution of poorly soluble phosphates in the soil.
