What is bio-organic fertilizer? How should it be used?

In recent years, bio-organic fertilizer has been gradually favored by the market, and it has become the first choice for growing organic crops, and there is a broad space for development, but many people do not know much about it, so what is bio-organic fertilizer? How should it be used?

What is bio-organic fertilizer?

Bio-organic fertilizer refers to the combination of specific functional microorganisms and organic materials mainly derived from animal and plant residues (such as animal and poultry manure, crop straw, etc.). It is a kind of fertilizer with the effect of both microbial fertilizer and organic fertilizer. The function of bio-organic fertilizer is mainly to improve soil, improve soil water and fertilizer conservation capacity, promote plant growth, improve plant disease prevention and resistance, improve fertilizer use efficiency, soil remediation, degradation of pesticides and other functions.

Compared with chemical fertilizer, bio-organic fertilizer has more complete nutrient elements. Long-term use of bio-organic fertilizer can effectively improve soil, regulate soil and rhizosphere microecological balance, improve crop resistance to diseases and pests and improve product quality.

Compared with farm manure and refined organic fertilizer, the fundamental advantage of bio-organic fertilizer is that the functional bacteria in bio-organic fertilizer have a specific effect on improving soil fertility and promoting crop growth, while farm manure and refined organic fertilizer are produced by natural fermentation. does not have the special effect of dominant functional bacteria.

Compared with microbial agents, bio-organic fertilizer contains functional bacteria and organic matter, in addition to improving soil, organic matter itself is the living environment of functional bacteria, functional bacteria are easy to colonize and play a role after being applied to soil, while biological fertilizer only contains functional bacteria, and the functional bacteria may not be suitable for some soil environment, can not survive or play a role. On the other hand, bio-organic fertilizer is cheaper than bio-bacterial fertilizer. Bio-organic fertilizer is of great significance to the realization of resource-saving and environment-friendly society, and it is the inevitable choice to realize the sustainable development of agriculture.

How should bio-organic fertilizer be used?

Bio-organic fertilizer chooses different fertilization methods according to different crops. The commonly used methods of bio-organic fertilizer are:

1. Seed application: when sowing by machine, mix granular bio-organic fertilizer with a small amount of chemical fertilizer and apply it to the soil with the seeder.

two。 Spreading method: combined with deep ploughing or sowing, bio-organic fertilizer is evenly applied to the area where the root system is concentrated and the soil layer that often remains moist, so as to achieve the integration of soil and fertilizer.

3. Strip ditch application: strip sowing crops or grape and other fruit trees, fertilizing and sowing after ditching or fertilizing at the distance from the 5cm of the fruit trees.

4. Ring ditch application method: apples, peaches, pears and other young fruit trees, 20-30cm from the trunk, open a ring ditch around the trunk, cover the soil after fertilization.

5. Radial furrow application: apples, peaches, pears and other adult fruit trees, 30cm from the trunk, according to the extension of the root system of fruit trees to open 4 50cm long ditches, cover the soil after fertilization.

6. Hole application: to sow or transplant crops, such as corn, cotton, tomatoes, etc., and apply fertilizer into the hole, then sow or transplant.

7. Dipping in the root method: for transplanting crops, such as rice and tomatoes, according to bio-organic fertilizer and 5 parts of water, the fertilizer suspension is dipped in the seedling root, and then planted.

8. The method of covering seed fertilizer: after ditching and sowing, cover the seeds evenly with bio-organic fertilizer.

Can bio-organic fertilizers completely replace pesticides?

Bio-organic fertilizer can improve soil environment, improve crop resistance, prevent soil-borne diseases and maintain crop health. However, the treatment effect is limited, and it is still necessary to use pesticides to treat crops that have already got the disease.
