Developing bio-organic fertilizer is one of the key ways to ensure the development of high-efficiency agriculture. Bio-organic fertilizer refers to a kind of special organic fertilizer that contains microbial strains with specific functions and has a secondary solid fermentation stage in the production process. After the bio-organic fertilizer processed by the organic fertilizer production line is applied to the soil, sufficient organic matter is used to provide sufficient energy materials for the exogenous functional microorganisms, so that these exogenous functional microorganisms are easy to colonize and reproduce in the soil, After the growth of crop roots, a large amount of root exudates will be secreted. These exogenous functional bacteria that have been colonized in the soil can converge to the root surface and rhizosphere, realize the regulation of rhizosphere microbial flora, and play the role of rhizosphere beneficial bacteria in activating nutrients, stimulating the growth of plant roots, and antagonizing soil-borne pathogens.
Improve soil fertility
95% of the trace elements in the soil exist in an insoluble form and cannot be absorbed and utilized by plants. The microbial metabolites contain a large number of organic acids. These substances, like hot water added in ice, can quickly dissolve the trace elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other essential mineral elements of plants, and become nutrient elements that can be directly absorbed and utilized by plants, It has greatly increased the fertilizer supply capacity of the soil.
The organic matter in the organic fertilizer processed by the organic fertilizer production line increases the content of organic matter in the soil, reduces the soil cohesion, and strengthens the water and fertilizer retention performance of the sandy soil, so that the soil forms a stable granular structure, which can play a good role in the coordinated supply of fertility. After using organic fertilizer, the soil will become loose and fertile.
Improve soil quality and promote soil microbial reproduction
Organic fertilizer can make soil microorganisms multiply in large numbers, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, etc These beneficial microorganisms can decompose organic matter in soil, increase soil aggregate structure and improve soil composition.
Microorganisms reproduce very quickly in the soil. They are like an invisible net, and are complex. After the bacterial body of microorganism dies, a lot of tiny pipes are left in the soil. These tiny pipes not only increase the permeability of the soil, but also make the soil become fluffy and soft, and the nutrient water is not easy to lose, which increases the soil’s water and fertilizer storage capacity, and avoids and eliminates the soil’s hardening.
The beneficial microorganisms in the organic fertilizer processed by the organic fertilizer production line can also inhibit the propagation of harmful bacteria, so that less pesticide can be applied. If applied continuously for many years, it can effectively inhibit soil harmful organisms, save labor, money and no pollution.
At the same time, there are various active enzymes secreted by animal digestive tract and various enzymes produced by microorganisms in organic fertilizer. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved. Long-term and sustainable use of organic fertilizer can improve soil quality. If the quality of soil is fundamentally improved, we are not afraid of not producing high-quality fruit.
Provide comprehensive nutrition for crops and protect crop roots
Organic fertilizer contains a large number of nutrients, trace elements, sugars and fats required by plants. CO2 released from decomposition of organic fertilizer can be used as material for photosynthesis.
Organic fertilizer also contains 5% of nitrogen, phosphorus and potassium, and 45% of organic matter, which can provide comprehensive nutrition for crops.
At the same time, it has to be mentioned that organic fertilizer decomposes in the soil and can be transformed into various humic acids. It is a kind of macromolecular material with good complexing adsorption performance and has good complexing adsorption effect on heavy metal ions. It can effectively reduce the toxicity of heavy metal ions to crops, prevent them from entering the plant, and protect the roots of humic acid substances.
