Embodiment 1

[0026] A biochar-based organic fertilizer prepared by the following method:

[0027] S1. Weigh by weight: 25 parts of biochar, 2 parts of rhamnolipid, 5 parts of shell powder, 1 part of triacontanol, 0.5 part of superabsorbent polymer resin fiber (polyacrylate), carbon enzyme 5 copies;

[0028] S2. Place the weighed superabsorbent polymer resin fibers in water to make them fully absorb water and swell into solid hydrogels of corresponding shapes;

[0029] S3. After mixing the solid hydrogel with biochar, rhamnolipid, triacontanol, shell powder, and carbonase, and stirring evenly, dry it until the moisture content is about 10%, and press it into tablets to obtain a diameter of 6 mm and a weight of 0.08 g flake granules.

[0030] In this embodiment, the water content of the superabsorbent polymer resin fiber is about 10%. The biochar is formed by low-temperature carbonization of garden waste and / or agricultural waste.

Embodiment 2

[0032] A biochar-based organic fertilizer prepared by the following method:

[0033] S1. Weigh by weight: 35 parts of biochar, 8 parts of rhamnolipid, 15 parts of shell powder, 3 parts of triacontanol, 1 part of superabsorbent polymer resin fiber (protein), 10 parts of carbon enzyme ;

[0034] S2. Place the weighed superabsorbent polymer resin fibers in water to make them fully absorb water and swell into solid hydrogels of corresponding shapes;

[0035] S3. After mixing the solid hydrogel with biochar, rhamnolipid, triacontanol, shell powder, and carbonase, and stirring evenly, dry it until the moisture content is about 10%, and press it into tablets to obtain a diameter of 6 mm and a weight of 0.08 g flake granules.

[0036] In this embodiment, the water content of the superabsorbent polymer resin fiber is about 10%. The biochar is formed by low-temperature carbonization of garden waste and / or agricultural waste.

Embodiment 3

[0038] A biochar-based organic fertilizer prepared by the following method:

[0039] S1. Weigh by weight: 30 parts of biochar, 5 parts of rhamnolipid, 10 parts of shell powder, 2 parts of triacontanol, 0.75 parts of superabsorbent polymer resin fiber (polyacrylate), carbonase 7.5 copies;

[0040] S2. Place the weighed superabsorbent polymer resin fibers in water to make them fully absorb water and swell into solid hydrogels of corresponding shapes;

[0041] S3. After mixing the solid hydrogel with biochar, rhamnolipid, triacontanol, shell powder, and carbonase, and stirring evenly, dry it until the moisture content is about 10%, and press it into tablets to obtain a diameter of 6 mm and a weight of 0.08 g flake granules.

[0042] In this embodiment, the water content of the superabsorbent polymer resin fiber is about 10%. The biochar is formed by low-temperature carbonization of garden waste and / or agricultural waste.

[0043] In this specific implementation, during the dr...

Abstract

The invention relates to the field of organic matter fertilizers, in particular to a biochar-based organic fertilizer and a preparation method thereof. The biochar-based organic fertilizer is prepared from, by weight, 25-35 parts of biochar, 2-8 parts of rhamnolipid, 5-15 parts of shell powder, 1-3 parts of triacontanol, 0.5-1 part of super absorbent polymer resin fiber and 5-10 parts of carbon enzyme. The biochar organic fertilizer obtained by the invention is rich in nutrition, can improve the organic carbon content of soil, can remarkably improve the water and fertilizer retention performance of the soil, and realizes the release of nutrients, so that the nutrient utilization rate is improved, and the biochar organic fertilizer is environment-friendly; after the obtained biochar is applied, the yield increasing effect is obvious, and by taking corn and wheat planting as an example, compared with a blank control group, the yields are increased by about 21.7% and about 23.1% respectively.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a biochar-based organic fertilizer and a preparation method thereof. Background technique [0002] In agricultural production, traditional chemical fertilizers have many disadvantages. Not only will they pollute the environment during use, but the utilization rate of nutrients is very low. [0003] my country is a large agricultural country with abundant plant biomass resources. The total annual production of biomass resources such as crop straws has exceeded 1 billion tons. Except for a small part of the straw produced in agricultural production, which is effectively used by returning to the field, ammoniation, silage, fermentation and used as a culture medium for edible fungi, most of it is incinerated, which not only causes environmental pollution but also leads to a waste of resources. . At the same time, with the rapid development of economic development and urbanization...
