[0020] A kind of biochar fertilizer, is made from the raw material of following weight part:

[0021] 30kg of biochar powder, 20kg of human and animal manure, 4kg of waste molasses, and 15kg of additives.

[0022] The biochar powder is made by placing the straw in a carbonization furnace for dehydration and deoxygenation treatment, and after high-temperature carbonization, it is pulverized so that the particle size is ≤0.5mm, and the water content is controlled at 9%.

[0023] The human and animal manure is obtained by drying selected human and animal manure, pulverizing into powder, and mixing, and the water content is controlled at 15%.

[0024] The total humic acid of the waste molasses is ≥ 25%, the total nutrient is ≥ 6%, and the water content is ≤ 65%.

[0025] The additive is obtained by dissolving plant ash in water, adjusting the pH to 8.1 with ammonia water, filtering, and freeze-drying.

[0026] The preparation method of above-mentioned a kind of biochar fertilize...

[0032] A kind of biochar fertilizer, is made from the raw material of following weight part:

[0033] 45kg of biochar powder, 25kg of human and animal manure, 6kg of waste molasses, and 20 additives.

[0034] The biochar powder is made by placing the straw in a carbonization furnace for dehydration and deoxygenation treatment, and after high-temperature carbonization, it is pulverized so that the particle size is ≤0.5mm, and the water content is controlled at 9.5%.

[0035] The human and animal excrement is obtained by drying selected human and animal excrement, crushing it into powder, and mixing it evenly, and the water content is controlled at 18%.

[0036] The total humic acid of the waste molasses is ≥ 25%, the total nutrient is ≥ 6%, and the water content is ≤ 65%.

[0037] The additive is obtained by dissolving plant ash in water, adjusting the pH to 8.2 with ammonia water, filtering, and freeze-drying.

[0038] The preparation method of above-mentioned a kind of bioc...

Embodiment 3

[0044] A kind of biochar fertilizer, is made from the raw material of following weight part:

[0045] 60kg of biochar powder, 30kg of human and animal manure, 8kg of waste molasses, and 25kg of additives.

[0046] The biochar powder is made by placing the straw in a carbonization furnace for dehydration and deoxygenation treatment, and after high-temperature carbonization, it is pulverized so that the particle size is ≤0.5mm, and the water content is controlled at 8.9%.

[0047] The human and animal feces are obtained by drying selected human and animal feces, crushing them into powder, and mixing them evenly, and the water content is controlled at 20%.

[0048] The total humic acid of the waste molasses is ≥ 25%, the total nutrient is ≥ 6%, and the water content is ≤ 65%.

[0049] The additive is obtained by dissolving plant ash in water, adjusting the pH to 8.4 with ammonia water, filtering, and freeze-drying.

[0050] The preparation method of above-mentioned a kind of bi...

Abstract

The invention discloses biological carbon fertilizer, prepared form the following raw materials in parts by weight: 30-60 parts of biological carbon powder, 20-30 parts of human and animal excreta, 4-8 parts of waste molasses and 15-25 parts of additive. The biological carbon fertilizer disclosed by the invention takes crop straw as a feed composition; the straw adopted as a raw material by the biological carbon fertilizer has low cost and easily available source and is pulverized to form the biological carbon powder through dehydration and deaeration treatment and high temperature carbonization; the carbonization effect is good, the carbon content is greater than 25%, the carbonization rate of the straw is effectively improved; and the carbon fertilizer has high yield and good application effect, and can passivate heavy metal in soil and improve the activity of soil microbes. Meanwhile, the carbon fertilizer has a greater specific area and improves the organic content of soil; as low-cost non-chemical fertilizer, the product disclosed by the invention can provide a guarantee for organic agriculture and green agriculture; and the preparation method is simple, controllable and easy to implement.

Description

technical field [0001] The invention relates to the fields of high-value comprehensive utilization of biomass resources and environmental pollution control, in particular to a biochar fertilizer. Background technique [0002] No matter in the fields of food crops or commercial crops, fertilization has been used for a long time to improve crop yield and quality. From the earliest application of farm organic fertilizers to the application of inorganic fertilizers, and then to the application of organic-inorganic compound fertilizers. Fertilizer type, fertilization amount and ratio have a great impact on the yield and quality of food crops or economic crops. Although traditional fertilizers, especially organic-inorganic compound fertilizers, have played a good role in increasing crop yields. However, traditional fertilizers have an unreasonable ratio of ingredients and nutrients, which can hardly restore soil fertility, improve soil structure, and even cause side effects, suc...
