Description

A kind of organic-inorganic biological compound fertilizer

technical field

The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an organic-inorganic biological compound fertilizer prepared by fermenting a compound bacterial agent.

Background technique

Fertilizer is an essential substance in agricultural production. In recent decades, in the process of developing agricultural modernization, chemical fertilizers and pesticides have been widely used. However, the long-term application of chemical fertilizers has destroyed the soil structure and soil ecological balance. The organic matter and microorganisms have been greatly reduced, and the soil has become compacted and salinized. A large number of pesticides and some toxic and harmful substances remain, seriously endangering food health and human living environment.

At present, people have realized the harm of excessive application of chemical fertilizers, and began to pay attention to the production and application of organic fertilizers. A series of new fertilizers such as organic fertilizers, microbial fertilizers, and organic-inorganic compound fertilizers are gradually entering the market.

Organic fertilizer is rich in nutrients such as organic matter, humus, and medium and trace elements, which can supplement soil organic matter, improve soil water and fertilizer retention performance, and improve soil salinization and compaction. However, the content of effective nutrients, nitrogen, phosphorus, and potassium in organic fertilizers is relatively low, which cannot meet the nutrients required by crops.

Microbial fertilizers mainly rely on supplementing beneficial microorganisms to the soil, using the metabolism of microorganisms to convert inorganic elements into organic compounds that can be directly used by crops, fixing free nitrogen in the air and converting it into ammonium nitrogen, decomposing and releasing fixed phosphorus and potassium in the soil, And antagonism and predation relationship with harmful microorganisms to reduce the occurrence of various diseases and insect pests. However, microbial fertilizers also have deficiencies: 1) At present, most of the existing microbial fertilizers have single strains, such as nitrogen-fixing bacterial fertilizers, potassium bacterial fertilizers, and seaweed fertilizers. Degradation problem; 2) Since most soils currently lack organic matter, and microorganisms can only survive and metabolize normally in an environment with sufficient nutrients, if only microorganisms are supplemented, the survival rate of microorganisms in soil lacking in organic matter will be low and the number of deaths will be large; 3 ) Microbial fertilizers produced by individual fertilizer manufacturers have backward production technology, use unidentified strains for production, low content of effective bacteria, and excessive bacteria, which seriously restricts the healthy development of the microbial fertilizer industry.

Organic-inorganic compound fertilizer combines the characteristics of organic fertilizer and chemical fertilizer, which can improve soil structure to a certain extent. However, organic-inorganic compound fertilizers do not take into account the huge role of microorganisms in the soil. Without microorganisms, organic matter cannot be effectively decomposed and utilized. If the number of harmful microorganisms in the soil is dominant, supplementing organic matter will provide nutrients for its growth instead, leading to aggravation of crop diseases and insect pests.

The organic combination of microorganisms, organic substances and inorganic elements is a new way to develop modern high-efficiency fertilizers. Through their respective characteristics and interactions, the combined use of the three can not only improve the yield and quality of agricultural products, but also improve soil and restore soil. The role of soil ecosystems. However, at present, the production process of domestic bio-organic-inorganic compound fertilizers is relatively simple, and the chemical fertilizers, organic materials, and bacteria are simply physically mixed and then measured and packaged. For example, the Chinese patent application CN202276367B discloses a manufacturing method of bio-organic-inorganic compound fertilizers, in which the strains of Bacillus japonicus, Pseudomonas, and Azotobacter are fermented step by step and mixed in proportion to make composite bacteria Fermentation broth, compound bacteria fermentation broth and adsorption materials are granulated, dried, and screened to make microbial granules; black humic acid and bentonite are granulated, dried, and screened to make organic particles; urea, ammonium phosphate, and potassium chloride are mixed Inorganic fertilizer granules are made; finally, microbial granules, organic matter granules, and inorganic fertilizer granules are mixed in proportion and packaged to make compound fertilizers. Another example is that the Chinese patent application CN102795934B discloses a method for manufacturing microbial compound fertilizers. First, the original bacterial species is cultivated to obtain a compound bacterial agent, and the compound bacterial agent, nutritional components, and bacterial strain carriers are mixed in proportion to make a slurry; then mixed in proportion The remaining materials are granulated, dried and cooled, and classified to obtain a compound granular fertilizer; finally, the slurry is sprayed on the compound granular fertilizer for inoculation, dried at low temperature, cooled, and measured and packaged to obtain a microbial compound fertilizer. The above technical process is simple, simple physical mixing of microorganisms, organic matter and inorganic matter. If the mixing ratio is improper and the content of inorganic chemical fertilizers is too high, the resulting compound fertilizer will die more microorganisms; chemical fertilizers have not been transformed, and after being applied to the soil The utilization rate is less than 30%, the loss of nutrients is large, and the composition of organic matter is single, which cannot meet the comprehensive absorption of nutrients by crops.
