How to apply biological fertilizer
Biofertilizer (ie, bacterial fertilizer) is one of the important sources of fertilizer. There are fundamental differences between biofertilizers and non-living methods for applying fertilizers and organic fertilizers. Now, several commonly used biofertilizer application methods are described as follows: Rhizobium fertilizer: Applicable to legume crops and generally used as a seed dressing. 30-50 grams per acre plant bactericide, add appropriate amount of water and mix gently (do not hurt seed coat) adhere to the seed. Requirements with the broadcast with the broadcast, avoid drying and direct sunlight. More than 48 hours should be re-vaccinated. Cover seed immediately after sowing. If it is too late to seed with rhizobium, or if the seedlings show poor nodulation after emergence, they can be poured near the seedlings. For seeds that have been disinfected with pesticides, they should be disinfected 2-3 weeks before seed dressing with Rhizobium. Certain legumes have a certain rhizobia and cannot be used casually. Nitrogen-fixing agents: Various crops other than leguminous crops such as rice, wheat, cotton, sweet potato, corn, potatoes, vegetables, etc. can be applied. It can be used as basal fertilizer, topdressing, or with roots and seed dressings. Can not be applied simultaneously with strong acid, strong alkali or bactericidal pesticides and fertilizers. Nor can it be co-administered with large amounts of nitrogen fertilizer, at least 10 days apart. However, combined application of organic fertilizers, phosphorus and potash fertilizers will promote the activity of nitrogen-fixing bacteria. The amount of 0.5-1 kg per mu, first with water to wet the crop seeds, sprinkle with bacteria and mix well, it is best first with wheat bran, corn and phosphate fertilizer dubbed nutrient solution, and then down the seeds mix well. When topdressing, it can be mixed with soil excrement and applied in the vicinity of the plant. Antibacterial agents: Can reduce crop rotten species, rot, increase seedling rate, and can promote growth and promote early maturity. For some underground pests also have a certain degree of inhibition. Wheat and beans can be dressed with bacteria powder. First wet the seeds with water, 30-50 grams of bacteria powder per acre, mix well, can also be bacteria powder 5-10 parts, mixed with cake flour 10, fertilizer soil 100-300 parts of the cake on the fertilizer. For basal or topdressing, use 100-250 kg per acre. When applying in paddy fields, the above-mentioned mixed bacterial fertilizer should be stacked for 4-7 days before use. It is effective to mix with superphosphate for seed fertilizer. It can be mixed with pesticide but not with fungicides. Ammonium sulfate, ammonium nitrate Ammonium bicarbonate has an inhibitory effect on it, and it can be used for more than 10 days after application. Phosphorus bacteria agent. Generally can be divided into two kinds: one is organic phosphorus bacteria, with the help of enzymes produced in bacterial life activities, so that the use of organic phosphorus can be transformed into a form that can be used for plants; the other is inorganic phosphorus bacteria, through which it produces The acid strengthens the dissolution of insoluble phosphate salts in the soil. It can be used as basal fertilizer, seed fertilizer (soaking seed, seed dressing or hoe root) and top dressing. Mixed with organic fertilizers, nitrogen-fixing bacteria, and antibiotics, the best fertilizer effect. The validity period is usually from the time of delivery, about 3 months in summer and about 6 months in winter. Potassium bacteria agent: Also called silicate bacteria agent. A wide range of applications, rice, wheat, cotton, corn, vegetables and other crops can be applied. Used as base fertilizer, 25 kg per acre; used as a seed dressing, 5 kg per acre, mixed with dry fine soil into a thin paste seed dressing; used as chase fertilizer, 20 kg of bacterial fertilizer mixed with pig manure 50 lbs. The hole is applied in the sowing ditch. Immediately after application, cover soil and keep it in a dark and moist state. Should be based on the application of organic fertilizers and inorganic fertilizers, combined with other cultivation measures, such as timely irrigation and drainage, cultivating loose soil, etc.; the appropriate soil moisture, good ventilation, and create favorable environmental conditions for living microorganisms.
