Description

Biological carbon fertilizer and preparation method thereof

The invention relates to a fertilizer and a preparation method thereof, in particular to a biological carbon fertilizer and a preparation method thereof.

Biochar is the product of high temperature thermal cracking of biomass in a low oxygen environment. Biochar has abundant micropores, which can not only replenish the organic matter content of the soil, but also effectively preserve water and nutrients and improve soil fertility.

In general, biochar is alkaline, so biochar is used as a soil conditioner, applied to the soil to increase the pH value, and biochar is poorly viscous. Applying to the viscous soil can reduce the specific gravity and hardness of the soil and improve the physical properties of the soil. And farming performance. Although biochar can effectively improve soil quality, maintain soil fertility, and have environmental protection functions, biochar is a soil improvement material with relatively low nutrient content compared with other agricultural materials. Because of its low nutrient content, it is used in agriculture. The scope is not large. Therefore, the creators of the present invention believe that conventional biochar has the need for improvement.

In view of the deficiencies of the prior art, the creator of the present invention has created a biochar fertilizer comprising: a plant nutrient solution and a biochar powder in a weight ratio of 3:7 to 4:6; and the plant nutrient solution includes at least Moisture, and at least having a total nitrogen content of 4.8 ± 1 wt% of the total nutrient solution of the plant, and at least a water-soluble amino acid having an overall content of 19.54 ± 1 wt% of the total nutrient solution of the plant. The biochar fertilizer production method, step The main steps include:

1. Take the raw material of the biochar powder and dry the raw material of the biochar powder to form a dried biochar powder.

2. Taking a plant nutrient solution containing total nitrogen and a water-soluble amino acid, wherein the total nitrogen accounts for 4.8±1% by weight of the plant nutrient solution, the water-soluble amine The base acid accounts for 19.54±1% by weight of the plant nutrient solution. The plant nutrient solution is cut and stirred to uniformly spread the solid matter contained in the plant nutrient solution. Total nitrogen refers to the total amount of nitrogen in soil, fertilizer or plants. Nitrogen can be divided into organic nitrogen and inorganic nitrogen, and the sum of the two is called total nitrogen.

3. Adding the plant nutrient solution to the dried biochar powder, wherein the weight ratio of the plant nutrient solution to the dried biochar powder is from 3:7 to 4:6, and after mixing and stirring, the mixture is allowed to stand for 3 to 7 Days are formed.

After the plant nutrient solution is cut and stirred, the solid matter formed by the agglutination can be broken into smaller particles and uniformly dispersed in the plant nutrient solution. When the plant nutrient solution is mixed with the dried biochar powder, it is sufficiently absorbed by the pore-rich dry biochar powder. Moreover, since the plant nutrient solution is rich in amino acid and total nitrogen, it has a certain consistency and moisturizing effect, so when mixed with the dried biochar powder, the biochar powder can be kept certain The humidity forms a biochar that is not easily self-igniting, so as to greatly reduce the risk of spontaneous combustion during storage or transportation of biochar.

Since the plant nutrient solution is rich in amino acid and other nitrogen-containing nutrients, the biochar retaining soil improver obtained by the preparation method of the invention can be applied to agricultural land as a fertilizer to enhance the soil. Fertile. Moreover, since the biochar itself is rich in pores, when applied to the agricultural soil, the nutrients contained in the nutrient solution of the plant can be slowly released into the soil, so that the agricultural land can be maintained for a long time. Fertility.

The first figure is a flow chart of the manufacturing method of the present invention

The construction, features and embodiments of the present invention will be described with the aid of the drawings, and the reviewers will have a better understanding of the present invention.

The invention relates to a biochar fertilizer, comprising: a plant nutrient solution and a biochar powder, which are combined in a weight ratio of 3:7 to 4:6; and the plant nutrient solution comprises at least water, and at least has a nutrient solution of the plant The total nitrogen content of the total content is 4.8 ± 1 wt%, and at least the water-soluble amino acid having a total content of 19.54 ± 1 wt% of the total nutrient solution of the plant. As for the water, other nutrient materials and trace elements may be added, but the addition of the other nutrient materials or trace elements does not affect the weight ratio of total nitrogen and water-soluble amino acid in the plant nutrient solution.

Referring to the first figure, the present invention relates to a method for preparing a biochar fertilizer, the steps of which mainly include:

1. Take the raw material of the biochar powder and dry the raw material of the biochar powder to form a dried biochar powder. The means for drying can be sun drying, drying, and the like.

2. Taking a plant nutrient solution, which is subjected to liquid fermentation with molasses. The plant nutrient solution contains total nitrogen and water-soluble amino acid, wherein the total nitrogen accounts for 4.8±1% by weight of the plant nutrient solution, and the water-soluble amino acid accounts for the plant nutrient solution. 19.54 ± 1 wt%. The total nitrogen may be in the form of an inorganic nitrogen compound such as NH ₄ ⁺ or NO ₃ ^{- in terms of} inorganic nitrogen. The plant nutrient solution is cut and stirred to uniformly spread the solid matter contained in the plant nutrient solution. In a preferred embodiment, the plant nutrient solution is cut and stirred at a temperature of 60 to 80 ° C to make the nutrient solution of the plant less dense, so that the agitation and cutting process is smoother.

3. Adding a plant nutrient solution to the dried biochar powder, wherein the weight ratio of the plant nutrient solution to the dried biochar powder is 3:7 to 4:6, and after mixing and stirring, it is allowed to stand for 3 to 7 days. To form biochar containing nutrients. In a preferred embodiment, the plant nutrient solution and the dried biochar powder are mixed and stirred for 3 to 7 days, and then subjected to compression molding to form the biochar fertilizer containing nutrients.

4. After the plant nutrient solution is cut and stirred, the solid matter formed by the agglutination can be broken into smaller particles and uniformly dispersed in the plant nutrient solution. When the plant nutrient solution is mixed with the dried biochar powder, it is sufficiently absorbed by the pore-rich dry biochar powder. Moreover, since the plant nutrient solution is rich in amino acid and total nitrogen, it has a certain consistency and moisturizing effect, so when mixed with the dried biochar powder, the biochar powder can be kept certain The humidity forms a biochar that is not easily self-igniting, so as to greatly reduce the risk of spontaneous combustion during storage or transportation of biochar. In addition, since the plant nutrient solution is rich in amino acid and other nitrogen-containing nutrients, the biochar retaining soil improver obtained by the production method of the invention can be applied to agricultural land as a fertilizer to enhance The fertility of the soil.
