Problems solved by technology

[0005] Although many compound microbial fertilizers in the prior art have been applied to agricultural production practices, most compound microbial fertilizers are due to unreasonable strain composition or improper preparation operations. For example, the existing compound microbial fertilizers are basically single strains. Fermented and mixed separately to make a mixed bacterial liquid, concentrated and dried, or directly sprayed and adsorbed on the substrate, some or even most of the bacterial species may die during the mixing, concentration, drying, and adsorption processes; in addition, the preparation after adsorption The pH and salt concentration will inhibit beneficial microorganisms, so that the number of viable bacteria in the product cannot meet the requirements
Ultimately, the number of beneficial viable bacteria contained in the compound microbial fertilizer is low, which also reduces its fertilizer efficiency accordingly.

preparation example Construction

[0036] Please refer to figure 1 , the preparation method of above-mentioned compound microbial fertilizer that the present invention also provides, comprises the following steps:

[0037] Step 101: mixing a part of the agricultural organic waste with the solid bacterial agent to obtain a premix;

[0038] In this step, since the content of the solid bacterial agent is small, it is difficult to achieve a uniform effect after directly mixing it with other components. Once the mixing is insufficient, it will lead to unbalanced subsequent fermentation; therefore, using a small amount of agricultural organic waste to mix with solid bacterial agents first, and then mix with other materials, this operation is easy to achieve a mixing effect, making The solid bacterial agent is evenly dispersed in other materials.

[0039] Step 102: Adding liquid bacterial agent during the mixing process of organic manure, marine organic waste, remaining part of agricultural organic waste and premix,...

Abstract

The invention provides a composite microbial fertilizer and a preparation method thereof, and belongs to the field of composite microbial fertilizers. The composite microbial fertilizer is prepared form the following raw materials in parts by weight: 4-6 parts of organic manure, 2-4 parts of humic acid, 0.7-3 parts of agriculture organic waste, 0.2-0.4 part of marine organic waste, 0.01-0.02 part of a liquid inoculant and 0.005-0.01 part of a solid inoculant. According to the composite microbial fertilizer, on one hand, comprehensive, balanced and easy-to-absorb nutrients are provided for crops, healthy growth of the crops is accelerated, and the produced fulvic acid can be used for adjusting the crop growth as a plant growth regulator, and on the other hand, a lot of beneficial microorganisms are generated. Due to balanced and sufficient fermentation substrates, the produced microorganisms are not easy to die; the composite microorganisms are large in viable number; the composite microbial fertilizer is significant in fertilizer efficiency, environmental friendly, and harmless after being applied; and due to large content of microorganisms and organic matters, the soil structure is also improved.

Description

technical field [0001] The invention relates to the field of compound microbial fertilizers, in particular to a compound microbial fertilizer and a preparation method thereof. Background technique [0002] Compound microbial fertilizer is composed of specific microorganisms (phosphorus-dissolving, potassium-dissolving, nitrogen-fixing microorganisms) or other identified two or more microorganisms that are not antagonistic to each other and nutrients. It can provide, maintain or improve plant nutrition and improve agricultural products. Production of live microorganisms to improve yield or quality of agricultural products. [0003] Compound microbial fertilizer integrates the advantages of organic fertilizer, chemical fertilizer and microbial fertilizer, overcomes the shortcomings of organic fertilizer delays in the past, and is very convenient to apply; it overcomes the degradation of soil physical and chemical properties and the decline in the quality of agricultural produc...
