Embodiment 1

[0047] A soil conditioner with biogas residue and vermicompost as main ingredients, consisting of the following components:

[0048] Biogas residue 35kg Vermicompost 30kg Ammonified lignite 10kg Bran 5kg Bone meal 5kg

[0049] Soybean meal 5kg Calcium powder 7kg Silicon calcium magnesium sulfur fertilizer 1kg Lime powder 2kg

[0050] The preparation method of the above-mentioned soil conditioner based on biogas residue and vermicompost, the steps are as follows:

[0051]a, take weathered lignite, add ammonium bicarbonate in the proportion of 14.7% by weight, make it ammonium in the reaction kettle at 20~30 ℃ temperature condition for 24 hours, get coarse ammoniated lignite, sieve hole 2 centimeters after pulverizing sieve to produce ammoniated lignite with a particle size of less than 2 cm;

[0052] b Take the biogas slurry that has been anaerobically fermented for 50 to 60 days with cattle manure as raw material, filter the biogas slurry through a filter press, let it dry n...

Embodiment 2

[0076] The soil conditioner as described in embodiment 1, the difference is that,

[0077] Vermicompost 30kg Biogas residue 38kg Ammonified lignite 10kg Bran 5kg Bone meal 5kg

[0078] 5kg soybean meal, 4.5kg calcium powder; 0.3kg borax, 0.2kg copper sulfate

[0079] Bentonite 5kg.

[0080] The preparation method is the same as in Example 1.

Embodiment 3

[0082] The soil conditioner as described in embodiment 1, the difference is that,

Abstract

The invention relates to a soil amendment prepared from biogas residue and wormcast as main material and a preparation method of the soil amendment, which belongs to the technical field of recycling of organic fertilizer and agricultural waste resource. The soil amendment is composed of the main material, amine treated lignite, bone meal, bran, soybean meal, and the other additives. The method prepares the soil amendment by biogas residue and wormcast, utilizes waste reasonably and effectively, is low in cost, changes waste into treasure, and protects environment. In addition, the method has simple process, low energy consumption, easy operation, flexible production, and convenient usage, and is easy for large-area promotion and application.

Description

technical field [0001] The invention relates to a soil conditioner with biogas residue and vermicompost as main ingredients and a preparation method thereof, which belongs to the technical field of recycling of organic fertilizer and agricultural waste resources. Background technique [0002] With the development of large and medium-sized biogas projects in China. Biogas residue has gradually become a non-negligible agricultural waste resource. Biogas residue is mainly cellulose and hemicellulose after anaerobic digestion. It not only contains more than 20 kinds of nutrients necessary for plant growth, but also has a low survival rate of pathogenic microorganisms. , high organic matter content, high degree of humification, low density, strong adsorption, large specific surface area and other characteristics. It is suitable as raw material for the production of organic fertilizers, cultivation substrates, adsorbents, soil improvers, etc. [0003] In recent years, the scale ...
