What is the role of bio organic fertilizer and how to improve fertilizer efficiency

Increase soil organic matter content。Regular application of organic fertilizer can significantly increase the content of soil organic matter, which is conducive to maintaining the stability of soil organic matter and improving the physical and chemical properties of soil.

Promote the formation of soil aggregate structure。Soil organic matter, calcium carbonate and polysaccharides have a good effect on the stability of soil structure. The application of organic fertilizer can increase the content of soil organic matter more than the application of manure, especially the production of more five-carbon sugars, six-carbon sugars and polysaccharides.

This is particularly beneficial for the formation of water-stable aggregates, such as a significant increase in water-stable aggregates that are larger than them.

Provides nutrients。Organic fertilizer contains various nutrients required by crops, and the use of organic fertilizer can significantly increase the content of nutrients in the cultivated soil, especially potassium. In 1995, the Ministry of Agriculture surveyed the cultivated land in 12 provinces across the country, and found that the phosphorus content in the cultivated land increased compared with before 1990, while the cultivated land area lacking potassium and trace elements was expanded.

Regulates the nitrogen content of the soil**。In the early stage of decomposing large straws, microorganisms absorb nitrogen from the soil to form their own somatic cells, resulting in the biological fixation of soil nitrogen, which plays a role in temporarily preserving nitrogen. When the microorganisms die, this part of the nitrogen is decomposed and released.

In addition, the application of organic fertilizer increases the energy matter in the soil, and is also conducive to biological nitrogen fixation, the organic matter content in organic fertilizer can reach about 30%, and relevant data show that the energy released per carbon oxide can be used by nitrogen-fixing microorganisms to fix 10 40mg of nitrogen.

Improves the activity of soil microorganisms and soil enzymes。After the application of organic fertilizer, the number of microorganisms increased significantly, especially in the soil near the application of organic fertilizer, which had a good effect on accelerating the release of organic nutrients and activating the nutrients in the soil. In addition, organic fertilizers can reduce diseases in certain crops.

Other advantages of the application of organic fertilizers in agricultural production include:

1. Nutritional balance, promote crop growth, increase yield significantly, and high fertilizer efficiency;

2. Improve the quality of agricultural products;

3. Inhibit pathogenic bacteria and reduce pests and diseases;

4. Loosen and improve the soil to reduce nitrate pollution in the soil;

5. Increase the absorption of water by crops, enhance the drought resistance and lodging resistance of crops;

6. After scientific management, the crops planted can reach the national green food fertilizer standard "A" or "AA".

Bio-organic fertilizer mainly contains nitrogen, phosphorus and potassium nutrients, and the addition of microbial bacteria can promote plant absorption, thereby improving fertilizer efficiency.

Before planting, that is, when mixing the soil, mix it with ordinary garden soil, you can add some coconut soil or vermiculite and the like, and then sow seeds.

When planting, the bottom is the soil, then spread some organic fertilizer on the soil surface, and then cover with a layer of soil to plant things.

When the crops grow to a certain stage, the growth of the plant is obviously weakened at this time, so it is necessary to fertilize at this time. We can dig a small trench next to the plant and bury the bio-organic fertilizer in it.

Bio-organic fertilizer is a new type of fertilizer, and it is also a green fertilizer that can replace chemical fertilizer with great room for development in the future. In the Basic Standards for Organic Agriculture and Food Processing (ifoam), the main points of the regulations on the use of bio-organic fertilizers are "to promote natural systems and biological recycling, so that sufficient quantities of organic matter are returned to the soil for the purpose of maintaining and increasing soil organic matter, soil fertility and soil biological activity", "inorganic fertilizers are only considered as supplements and not substitutes for nutrient cycling", "the use of chemically synthesized fertilizers and chemically synthesized growth regulators", It must be limited to the extent that it does not have adverse consequences for the environment and the quality of the crop, and does not allow the accumulation of toxic residues in crop products to the extent that it affects human health".

In the production of green food, great attention must be paid to the protection of a good ecological environment, and the excessive use of inorganic fertilizers must be limited. The benefits of using bio-organic fertilizer are as follows: Bio-organic fertilizer contains a variety of beneficial microorganisms, ammonia cryptonic acids, peptides, enzymes, and antibiotics from microsones.

Bio-organic fertilizer can reduce carbon and nitrogen, but if the carbon to nitrogen ratio is too large, the decomposition rate of microorganisms is slow, and the available nitrogen in the soil is depleted. At the same time, it can inhibit plant pathogenic bacteria, improve the microbial environment and physical structure in the soil, improve the plant's own immunity, and improve the quality and storage and transportation resistance of crops.

It contains microbial flora, and the microflora has good environmental adaptability, and it is easy to give full play to the advantages of microflora. Good nutritional function and high fertilizer efficiency. It contains organic nutrients and inorganic nutrients, and is small in size and easy to apply.

The fertilizer efficiency of organic fertilizer is produced by the joint action of the fertilizer efficiency of beneficial microorganisms and the fertilizer efficiency of organic fertilizer, and the organic fertilizer is a better soil amendment to improve the soil structure, which can make the formation of soil aggregate structure and the improvement of soil physical form mainly lie in the increase of non-capillary porosity, the increase of large water-stable aggregates, the improvement of soil structure, and soil aeration.

Organic fertilizers contain nutrients that are needed for the growth of crops. The first feature is that the adsorption capacity of organic matter is large, and the nutrients are not easy to be lost; Secondly, it is easy to be absorbed and utilized by crops. The application of organic fertilizer can not only supplement soil nutrients, but also extract nutrients from the soil and regenerate the nutrients absorbed by nutrients, reducing the shortage of soil nutrients.

Some organic acids or organic matter clusters produced by the decomposition of organic fertilizers are chelated or complexed with iron and aluminum, thereby reducing the fixation of phosphorus in the soil;

All kinds of organic fertilizers are rich in organic matter, which provides nutrients and energy for soil microorganisms, accelerates the growth and reproduction of microorganisms, not only increases their number, but also plays an important role in the leasing of organic matter, the accumulation of nutrients, and the synthesis of humus. Under the action of microorganisms, organic nutrients are continuously decomposed into nutrients that plants can absorb and utilize, and some nutrients fixed in the soil can also be released. Microorganisms decompose phosphorus-containing compounds and release phosphorus from the soil.
