Description
Technical field
The invention belongs to agriculture field, be specifically related to a kind of preparation method who improves the corn specific complex microorganism fertilizer of soil, also relate to the product by the method preparation.
Background technology
Flourish along with the tertiary industry, the raiser in rural area is more and more, and when the raiser increased, cultivation ight soil was also in continuous increase.The nutritive substance that wherein contains many not digested absorptions, such as the robust fibre in the ruminating animal ight soil, the nitrogen in pig, the chicken manure, the calcium equal size in the batterylaying ight soil is all higher, and the very large potentiality of utilizing are arranged.If these ight soil can not get processing timely and effectively, will seriously take and contaminated soil, water body, produce foul gas and cause severe contamination.Traditional dejecta treatment method be with ight soil directly as fertilizer, but complicated organism, macromolecular cpd are can't be by cell walls and the cytolemma of root hair cell; Therefore organic fertilizer discharges to soil, must complicated organic substance decomposing be become simple composition by soil microorganisms, or ionization could absorb; Must convert ammonia-state nitrogen (NH to such as nitrogenous fertilizer
4+) and nitric nitrogen (NO
3-), phosphate fertilizer must convert phosphate radical (PO4 to
3-), potash fertilizer must convert potassium ion (K to
+) crop could absorb.And existing fertilizer mainly utilizes microorganism that the macromole in the organic fertilizer is decomposed into small molecules, but the rear beneficial microorganism that is manured into soil can not continue breeding, therefore can not fundamentally improve because partially execute, singly execute, heavy dressing chemical fertilizer, cause soil acidity or alkalinity to change, organic content reduces, soil compaction is serious, water conservation, fertilizer conservation, ventilation property extreme difference, the problem such as beneficial organism flora minimizing in the soil.
Corn is one of China's three generalized grain kinds, and corn is roughly nitrogen 30%-50% to chemical fertilizer utilization ratio according to statistics, phosphorus 10%-20%, potassium 40%-70%.But because partially execute in recent years, singly execute, heavy dressing chemical fertilizer, cause soil acidity or alkalinity to change, organic content reduces, soil compaction is serious, the beneficial organism flora reduces in the soil, the microecological balance havoc causes corn not high to the utilization ratio of chemical fertilizer.Therefore, be badly in need of a kind of reasonable utilization cultivation ight soil, and can improve the fertilizer of soil micro-ecosystem, improve soil aggregate, improve corn to the utilization ratio of chemical fertilizer, thereby the raising corn yield, simultaneously beneficial microorganism can symbiotic co-existence behind the incorporation of fertilizerin the soil, improves the microecological balance of soil.
