Rational application of biological fertilizer

The types of biological fertilizers are different and their usages are different. The amount of pure biological fertilizer is small, generally 0.5-2 kg per mu, for seed dressing, dipping root or foliar spray application. For example, the soybean root nodule fertilizer can be inoculated by the mud method, and a microbial agent is added to 0.5-1 part of rice soup to prepare a paste and mixed on the soybean seed. Bio-organic and inorganic compound fertilizer, generally 30-75 kg per mu, used as a base fertilizer or seed fertilizer for mechanical sowing. The bio-organic fertilizer is generally used in a large amount, and 50-80 kg per mu is applied as a base fertilizer application. When the bio-organic fertilizer is used as a base fertilizer in dry fields, it can be applied in one piece in combination with autumn and spring. The paddy field is used as a base fertilizer and is applied before the leeches.

In the production, transportation and use of biological fertilizers, the following five points should be noted: 1 processing and production of fertilizer, drying temperature should not exceed 80 degrees, otherwise affect the number of live bacteria; 2 in storage and transportation of biological fertilizers, should avoid moisture or rain 3 When using biological fertilizer for seed drying, avoid direct sunlight; 4 the use of biological fertilizer must consider the physical, chemical and biological factors of the soil; 5 biological fertilizer can not be used with pesticides such as seed coating agents and physiological acid fertilizers.
