Problems solved by technology

The fertilizer efficiency of microbial fertilizers is directly affected by quality factors such as the number of effective bacteria contained in the fertilizer and the size of the activity. Only when these beneficial microorganisms are vigorously multiplying and metabolizing can the material transformation and beneficial metabolites be continuously formed and exert their full potential. effect, otherwise it will directly affect the quality of the fertilizer, resulting in a decline in fertilizer efficiency

Embodiment 1

[0035] An organic-inorganic compound full-nutrient microbial fertilizer, the preparation method of which comprises the following steps:

[0036] S1. Preparation of organic fertilizer granules

[0037]Premix sheep manure or cow manure with broken straw at a mass ratio of 4:1, add 1wt.% EB decomposing agent, stir and add water to adjust the humidity of the mixed material to 60%, and then carry out biological fermentation. After the fermentation is completed, press the product Add 1-2% of calcium sulfate, magnesium sulfate, zinc sulfate monohydrate and / or manganese sulfate monohydrate to adjust the content of calcium, magnesium, zinc and manganese elements by dry weight. Granulating to make organic fertilizer granules;

[0038] S2. Functional bacteria culture load

[0039] Weigh the organic fertilizer particles and crush them, add porous carbon material and polyaniline gel, the mixing ratio of the organic fertilizer particles and the porous carbon material, polyaniline gel is 2...

Embodiment 2

[0048] An organic-inorganic composite full-nutrient microbial fertilizer, the preparation method of which is the same as in Example 1, except that the porous carbon material is replaced by an equivalent amount of commercial activated carbon.

Embodiment 3

[0050] An organic-inorganic compound full-nutrition microbial fertilizer, its preparation method is the same as that of Example 1, the difference is that: the porous calcium carbonate of 7wt.% is also included in the described culture substrate, and the preparation method of the porous calcium carbonate comprises the following steps:

[0051] Weigh the soluble starch and dissolve it in deionized water according to the ratio of solid to liquid 0.5g / 100mL, stir and heat up to 70-80°C and keep it warm for 36min until the dissolution is complete. After natural cooling to 50°C, add the final concentration of 1.8 Calcium acetate of g / 100mL, after dissolving completely, add an equal volume of 0.96g / 100mL ammonium carbonate solution, stir and react for 10h, separate the precipitate, wash with deionized water, and vacuum dry to obtain the porous calcium carbonate.

Abstract

The invention provides a preparation method of an organic-inorganic composite full-nutrient microbial fertilizer, and belongs to the technical field of microbial fertilizer preparation, and the preparation method comprises the following steps: mixing and fermenting animal waste, crushed straw and a decomposition agent, adding an inorganic salt regulator to regulate components, aging and decomposing, and granulating; adding a porous carbon material and a polyaniline gel material into the aged organic fertilizer, inoculating functional bacteria for culture, and coating organic fertilizer particles with a culture load product; finally, after urea, diammonium phosphate and potassium sulfate are compounded, adjusting the content of nutrients and functional bacteria, and preparing the microbial fertilizer. The fertilizer is comprehensive in nutrition and uniform in fertilizer supply, the use amount of the fertilizer can be reduced, the contained functional bacteria can accelerate organic matter decomposition, and the fertilizer has the effects of increasing the utilization rate of the fertilizer and activating and improving soil.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizer preparation, in particular to a preparation method of an organic-inorganic composite full-nutrient microbial fertilizer. Background technique [0002] Fertilizer is an important means of agricultural production, and the sustainable and stable development of agriculture is inseparable from fertilizer. Chemical fertilizers are widely used in production because of their rich content of available nutrients and significant yield-increasing effects. However, the long-term and large-scale use of chemical fertilizers can easily lead to soil compaction, decline in crop quality, and even cause environmental pollution. Microbial fertilizers can improve soil structure, improve fertilizer efficiency, create a rhizosphere environment dominated by beneficial microorganisms, and promote crop growth. It plays an important role in increasing yield, improving crop quality, increasing crop resistance, a...
