specific Embodiment approach 1

[0030] Embodiment 1: This embodiment is a biochar-based organic fertilizer dedicated to millet, which consists of 60 to 70 parts of sheep manure, 10 to 15 parts of peat soil, 15 to 20 parts of straw, and rotten fertilizer in parts by weight. It consists of 5-10 parts of phytic acid, 15-20 parts of biochar and 0.1-1 part of microbial fermentation agent.

specific Embodiment approach 2

[0031]Specific embodiment two: this embodiment is the preparation method of special biochar-based organic fertilizer for millet in specific embodiment one, and the specific steps are as follows:

[0032] 1. Fermentation: Weigh 60-70 parts of sheep manure, 10-15 parts of peat soil, 15-20 parts of straw, 5-10 parts of humic acid, 15-20 parts of biochar and 0.1 to 1 part of microbial fermentation agent;

[0033] Mix 60 to 70 parts of sheep manure, 10 to 15 parts of peat soil and 15 to 20 parts of straw and stack them into a fermentation tank with a depth of 1.5 meters, and add 0.1 to 1 part of microbial fermentation bacteria agent, and then add water to make the mass fraction of water in the mixed material in the fermentation tank be 60% to 70%, and build a heap for closed fermentation for 2 to 3 days. , use a compost turner to turn the compost for the first time, then spray water so that the mass fraction of water in the mixed material in the fermentation tank is 60% to 70%, st...

specific Embodiment approach 3

[0040] Embodiment 3: The difference between this embodiment and Embodiment 2 is that the microbial fermentation agent described in step 1 is an HB decomposing agent. Others are the same as in the second embodiment.

Abstract

The invention relates to a biochar based organic fertilizer and a preparation method thereof, in particular to a biochar based organic fertilizer special for millet and a preparation method thereof. The invention aims to solve the technical problems that existing millet fertilization can cause slow growth rate of millet, excess fertilizer application can result in environmental pollution and decline of grain eating quality. The biochar based organic fertilizer provided by the invention is composed of sheep manure, turfy soil, straw, humic acid, biochar and a microbial fermentation agent. The preparation method of the biochar based organic fertilizer provided by the invention includes: 1. fermentation; 2. mixing; 3. granulation; 4. drying; 5. cooling; 6. screening; and 7. packaging. The biochar based organic fertilizer special for millet reaches the effects of drought resistance, land cultivation, production increase, and enhancement of nutrition and eating quality, and is an optimal fertilizer source for organic cultivation of millet. The organic materials needed by the organic fertilizer provided by the invention are organic waste and are easily available, also the cost is low, the process is advanced, and the method can achieve large-scale production.

Description

technical field [0001] The invention relates to a biochar-based organic fertilizer and a preparation method thereof. Background technique [0002] The scientific name of millet is millet, and the hulled millet is called millet. It is an important crop in my country. It is rich in various vitamins, the protein content is between 11.2% and 13.4%, and the fat content is higher than that of rice and flour. In addition, it contains the amino acids needed by the human body in a coordinated proportion, and the crude fiber content is the lowest among food crops. According to "Shen Nong's Materia Medica", millet has the functions of nourishing kidney qi, eliminating stomach heat, quenching thirst (diabetes), and diuresis. In order to increase the yield of millet, growers invest a large amount of chemical fertilizers and pesticides. The use of these chemical products has brought serious consequences to agricultural production. The organic matter content of farmland soil is low, the ...
