Description
Technical field
The invention belongs to biological fertilizer field, be specifically related to a kind of micro organism composite fertilizer improving cropper resistance.
Background technology
Using of chemical fertilizer provides new nutrient source for crops, has produced more and better agricultural product,
But singly execute in a large number for a long time, partially execute chemical fertilizer have resulted in soil compaction, soil fertility decline, field pest and disease damage show effect in a large number, agricultural
Increase production inconspicuous, and bring a series of problems such as environmental pollution.Just it is being devoted to exploration for the researcher of this all parts of the world to carry
High chemical fertilizer utilization rate reaches balance fertilizing, the rational application of fertilizer to overcome the approach of its drawback.Microbial manure is solving this side
The effect of uniqueness is had in the problem of face.
Composite microbial manure is microorganism, and a class compound with nutrient substance contains microorganism alive and in use can
Obtaining the fertilizer of specific fertilizer effect, it can improve Soil structure and character by the vital metabolic activity of microorganism,
Chesson prevents from hardening, and alleviates the deterioration of ecological environment of soil, may be provided for simultaneously, keeps or improve crop alimentary, increases
Pretend the resistance against diseases of thing, improve agricultural output or improve quality of agricultural product.At present, prepare microbial manure to be typically employed in
Granulation process adds microbial inoculum, but the high-temperature process in granulation process can cause a large amount of microbial inoculum dead, reduces fertilizer and buries
After effect.Further, since the microorganism in microbial manure can not directly contact with chemical fertilizer, Insecticides (tech) & Herbicides (tech) etc.,
Otherwise can cause microorganism mortality, therefore microbial manure also exists activity microbial inoculum add difficulty, COMPONENTS COMPATIBILITY want
Asking high, the inhibitory action balance between carrier material and microbial material, complex process, product quality is difficult to reach requirement and guarantor
The problem such as keep steady fixed.Therefore, many research worker are devoted to explore novel microbial manure to overcome drawbacks described above.
