Problems solved by technology

Because the country has strict standards for organic agriculture and bio-organic fertilizer production, bio-organic fertilizer refers to specific functional microorganisms and mainly animal and plant residues (such as livestock and poultry manure, crop straw, etc.) A type of fertilizer compounded by organic materials that has both the effects of microbial fertilizers and organic fertilizers. Organic planting does not require the addition of any chemical fertilizers and soil conditioners, so its products cannot be applied to organic agriculture.

Embodiment 1

[0033] (1) Preparation of biomass straw charcoal: After drying and pulverizing 33kg of crop rice straw, carry out high-temperature pyrolysis carbonization treatment in a furnace at 400-600°C for 3 hours, and obtain 20kg of biomass straw charcoal after cooling and crushing. The flue gas formed during the heating process is separated by condensation equipment to produce by-products such as wood vinegar.

[0034] (2) Pretreatment of chicken manure: Add 55kg of raw chicken manure to 1.1kg of RW fermenting agent for organic fertilizer production in the greenhouse for aerobic fermentation, and ensure that the special RW fermenting agent for organic fertilizer production can be mixed with the The raw chicken manure is mixed evenly. During the fermentation process, ventilation is ensured. The fermentation period is 20 days. Stir and stir again in the middle. After fermentation, dry to a moisture content of 20% for later use.

[0035] (3) Soybean meal pretreatment: add 0.3kg of Ames or...

Embodiment 2

[0038](1) Preparation of biomass straw charcoal: After drying and pulverizing 58kg of crop rice straw, conduct high-temperature pyrolysis carbonization treatment in a furnace at 400-600°C for 3 hours, and obtain 35kg of biomass charcoal raw material after cooling and crushing. The flue gas formed during the heating process is separated by condensation equipment to produce by-products such as wood vinegar.

[0039] (2) Pretreatment of chicken manure: add 96.25kg of raw chicken manure to 1.93kg of RW fermentation agent for organic fertilizer production in the greenhouse for aerobic fermentation, and overthrow and stir to ensure that the special RW fermentation agent for organic fertilizer production can be compatible with the The chicken manure is mixed evenly. During the fermentation process, ventilation is ensured. The fermentation period is 20 days. Stir and stir again in the middle. After the fermentation process, it is dried to a moisture content of 20% for later use.

Abstract

The invention relates to a charcoal-based organic fertilizer and a preparation method thereof. The charcoal-based organic fertilizer has the advantages of low cost, environment friendliness, good fertilizer efficiency, wide application range, high fertilizer efficiency utilization rate and pest prevention. The preparation method comprises the steps as follows: adding starter cultures to chicken manure and soybean meal respectively for fermentation, after drying, crushing and mixing crop-residue-derived carbon, the treated chicken manure and soybean meal with ground phosphate rock, adding wood vinegar to the mixture with stirring, performing granulation, and obtaining the charcoal-based organic fertilizer after cooling and drying.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a biochar-based organic fertilizer for organic planting and a preparation method thereof. Background technique [0002] Biochar is not ordinary charcoal, it is a kind of charcoal with extremely rich carbon content. It is the carbonization of wood, grass, corn stalks or other crop waste through pyrolysis in a low-oxygen environment. This kind of charcoal formed by plants to fix carbon is called "biochar" by scientists. Biochar is almost pure carbon, and it will not disappear for hundreds to thousands of years after being buried in the ground, which is equivalent to sequestering carbon into the soil. Biochar is rich in micropores, which can not only supplement the organic matter content of the soil, but also effectively preserve water and nutrients and improve soil fertility. In fact, the reason why fertile soil is mostly black is because of the high carb...
