Embodiment 1

[0017] The preparation method of biochemical compound fertilizer of the present invention is as follows:

[0018] 1) Cultivation of strains: Inoculate Bacillus natto into the seed medium, and cultivate at 40°C for 7 hours to obtain seed liquid;

[0019] 2) Preparation of materials to be fermented: Take 46kg of livestock manure, 5kg of household garbage, 9kg of leaves, 12kg of crop straw, 4kg of weeds, 11kg of nitrogen fertilizer, 9kg of phosphate fertilizer, and 6kg of potassium fertilizer;

[0020] 3) Fermentation: Spray the cultured seed liquid evenly into the material to be fermented according to 2% of the weight of the material to be fermented, mix evenly, and cultivate at 50°C for 35 days, and the finished product is obtained after the fermentation is completed;

[0021] Wherein, the mass percent of each component in the seed culture medium is: aspartic acid 7%, glucose 4%, and the rest is water.

Embodiment 2

[0023] The preparation method of biochemical compound fertilizer of the present invention is as follows:

[0024] 1) Cultivation of strains: Inoculate Bacillus natto into the seed medium, and cultivate at 35°C for 6 hours to obtain seed liquid;

[0025] 2) Preparation of materials to be fermented: Take 40kg of livestock manure, 1kg of household garbage, 7kg of leaves, 8kg of crop straw, 5kg of weeds, 12kg of nitrogen fertilizer, 10kg of phosphate fertilizer, and 7kg of potassium fertilizer;

[0026] 3) Fermentation: Spray the cultivated seed solution evenly into the material to be fermented according to 2% of the weight of the material to be fermented, mix evenly, cultivate at 55°C for 30 days, and obtain the finished product after fermentation;

[0027] Wherein, the mass percent of each component in the seed culture medium is: aspartic acid 10%, glucose 2%, and the rest is water.

Embodiment 3

[0029] The preparation method of biochemical compound fertilizer of the present invention is as follows:

[0030] 1) Cultivation of strains: Inoculate Bacillus natto into the seed medium, and cultivate at 45°C for 8 hours to obtain seed liquid;

[0031] 2) Preparation of materials to be fermented: Take 50kg of livestock manure, 7kg of domestic garbage, 12kg of leaves, 15kg of crop straw, 3kg of weeds, 10kg of nitrogen fertilizer, 8kg of phosphate fertilizer, and 4kg of potassium fertilizer;

[0032] 3) Fermentation: Spray the cultured seed liquid evenly into the material to be fermented according to 2% of the weight of the material to be fermented, mix evenly, cultivate at 60°C for 37 days, and obtain the finished product after fermentation;

[0033] Wherein, the mass percent of each component in the seed culture medium is: aspartic acid 2%, glucose 5%, and the rest is water.

Abstract

The invention provides a biochemical compound fertilizer and a preparation method thereof. The preparation method comprises the following steps: inoculating Bacillus natto into a seed culture medium, and culturing to obtain a seed solution; proportionally mixing livestock and poultry excrement, domestic waste, leaves, crop straws, weeds, a nitrogen fertilizer, a phosphate fertilizer and a potassium fertilizer; and evenly spraying the cultured seed solution into the materials to be fermented, evenly mixing, and culturing at 50-60 DEG C for 30-37 days, thus obtaining a finished product when fermentation is finished, wherein the seed culture medium contains the following components in percentage by mass: 2-10% of aspartic acid, 2-5% of glucose and the balance of water. The biochemical compound fertilizer provided by the invention can provide sufficient nutrient for crops, thereby being applicable to the growth of the crops; the raw materials of the biochemical compound fertilizer are low in cost and accessible, so that the cost of the fertilizer is reduced; and the nitrogen fertilizer, the phosphate fertilizer and the potassium fertilizer are added, so that organic substances in the soil can be supplemented, the micro ecological environment can be improved, and the defect of slow action of an organic fertilizer can be compensated.

Description

technical field [0001] The invention belongs to the field of agricultural chemical fertilizers, in particular to a compound fertilizer. Background technique [0002] The existing bio-organic fertilizers generally use straw or manure as raw materials, which has certain significance for environmental protection and sustainable agricultural development. It has been found through research that domestic garbage, leaves, weeds, etc. can fully meet the requirements of bio-organic fertilizer raw materials in terms of related substance content, but they are rarely used in practice. How to better apply them to bio-organic fertilizers to reduce bio-organic fertilizers The cost of organic fertilizer and better environmental protection have become an urgent problem to be solved. Contents of the invention [0003] The invention provides a biochemical compound fertilizer, and therefore, the invention also provides a preparation method of the biochemical compound fertilizer. [0004] ...
