Embodiment 1

[0106] The present embodiment provides a kind of preparation method that is applicable to the compound microbial fertilizer of crayfish culture, comprises the following steps:

[0107] Step A: Anaerobic fermentation:

[0108] Use a straw grinder to crush corn stalks with a moisture content of 25% to a particle size of 20mm, and feed them with chicken manure with a moisture content of 80% and biogas slurry with a moisture content of 90% at a mass ratio of 1:8:6 , so that the moisture content of the material in the high-dry anaerobic reactor (the DANAS high-dry anaerobic reactor developed by Beijing Zhongchi Green Energy Environmental Technology Co., Ltd.) can be maintained at a level of 80.3%, and the material enters the high-dry anaerobic reactor for Anaerobic fermentation to obtain anaerobic digestion liquid, the fermentation period is 30 days, and the fermentation temperature is 50°C;

[0109] Step B: Dehydration:

[0110] Transfer the anaerobic digestion solution to a scr...

Embodiment 2

[0124] The present embodiment provides a kind of preparation method that is applicable to the compound microbial fertilizer of crayfish culture, comprises the following steps:

[0125] Step A: Anaerobic fermentation:

[0126] Feed cow dung with a moisture content of 80% into a high-dry anaerobic reactor (such as the DANAS high-dry anaerobic reactor developed by Beijing Zhongchi Green Energy Environmental Technology Co., Ltd.), so that the moisture content of the material in the reactor is controlled at 80% level, enter the anaerobic reactor for anaerobic fermentation, the fermentation period is 25 days, and the fermentation temperature is 48°C;

[0127] Step B: Dehydration:

[0128] Transfer the anaerobic digestion solution to a screw extrusion dehydrator for solid-liquid separation to obtain biogas residue with a moisture content of 70% and biogas slurry with a moisture content of 90%;

[0129] Step C: Aerobic fermentation:

[0130] Mix biogas residue with a moisture conte...

Embodiment 3

[0142] The present embodiment provides a kind of preparation method that is applicable to the compound microbial fertilizer of crayfish culture, comprises the following steps:

[0143] Step A: Anaerobic fermentation:

[0144] The soybean straw with a moisture content of 25% is crushed to a particle size of 10mm by a hammer-type straw grinder, and the biogas slurry with a moisture content of 93% is fed in a mass ratio of 2:11 to make the high-dry anaerobic reactor (The DANAS high-dry anaerobic reactor developed by Beijing Zhongchi Green Energy Environmental Technology Co., Ltd. can be used) The moisture content of the material in the anaerobic reactor is maintained at 82.3%, and it enters the anaerobic reactor for anaerobic fermentation. The fermentation period is 28 days. The fermentation temperature is 45°C to obtain anaerobic digestion solution;

[0145] Step B: Dehydration:

[0146] Transferring the anaerobic digestion solution to a screw extrusion dehydrator to remove a ...

Abstract

The invention discloses a preparation method of a compound microbial fertilizer suitable for crayfish culture. The preparation method comprises the following steps: step A, performing anaerobic fermentation to obtain anaerobic digestion liquid; step B, dehydrating to obtain biogas residues with the water content of 65-70%; step C, performing aerobic fermentation to obtain an aerobic fermentation material; step D, aging to obtain an organic fertilizer; step E, mixing the manufacturing materials of the compound microbial fertilizer in proportion to obtain a mixed material; step F, granulating: granulating the mixed material to obtain columnar fertilizer particles with the particle size of 3-5mm; step G, drying: drying the columnar fertilizer particles, and cooling to obtain fertilizer particles with the water content of 10-20%; and step H, adding probiotics to prepare the compound microbial fertilizer suitable for crayfish culture. The compound microbial fertilizer is better in water fertilizing effect, and can promote proliferation of diatom after being applied, so that the number of diatom in a water body is higher, and the growth speed of crayfish seedlings is higher. Therefore, the fertilizer disclosed by the invention is suitable for crayfish culture.

Description

technical field [0001] The invention relates to the field of microbial fertilizer production, in particular to a production method of compound microbial fertilizer suitable for crayfish farming. Background technique [0002] As a table delicacy, crayfish is becoming more and more popular among consumers. The huge consumer market also promotes the rapid growth of crayfish farming. In the process of cultivating crayfish, it is necessary to carry out fertilizer and water, that is, to enrich the water body in the pond by adding nutrients, increase the growth of algae and aquatic plants in the water, provide rich bait for the growth of crayfish, and increase the water temperature at the same time. Inhibit the growth of moss, improve the survival rate and growth rate of crayfish seedlings. [0003] The current fertilizer and water measures are mainly to add chemical fertilizers or livestock and poultry manure to the water body. Adding chemical fertilizers is not easy to control,...
