The use of bacterial fertilizer for the improvement of vegetable soil can not be reduced.
Good soil is the basis of high yield and high quality of vegetables, but with long-term continuous cropping and unreasonable application of chemical fertilizer, the soil environment in most vegetable areas in China is getting worse and worse, which is extremely disadvantageous to the growth of vegetables. The improvement of the soil in the vegetable area has already reached the point where we must pay attention to it.
?
Problem 1: serious soil consolidation, salinization and acidification
Continuous cropping and a large number of chemical fertilizers seriously damage the soil aggregate structure, resulting in soil consolidation, poor air permeability, salinization and acidification, which makes it difficult for vegetable crops to take root, even if they can take root. retting roots will also occur because the soil oxygen content is too low.
Solution:
The application of microbial agents can effectively solve the serious problems of soil consolidation, salinization and acidification. Microbial agents can improve soil aggregate structure, make the soil more loose and breathable, help root system to tie down, and absorb sufficient water and nutrients for vegetables.

Problem 2: decrease of beneficial bacteria in soil and imbalance of flora
With the extension of soil planting years and the increase of continuous cropping, there are more and more harmful microorganisms in soil, but beneficial microorganisms can not be replenished in time, which makes soil-borne diseases spread wantonly, resulting in dead seedlings, dead seedlings and other harm.
Solution:
To solve the problem of soil-borne diseases caused by the imbalance of soil flora, sterilization alone can not play a radical role. It is necessary to supplement the beneficial microorganisms in the soil by directly applying microbial agents, so that it can restrain or kill harmful bacteria through its own life activities, so as to effectively control the occurrence of all kinds of soil-borne diseases.
