Embodiment 1

[0038] 1. The process of preparing peanut shell biochar is as follows:

[0039] (1) Air-dry the peanut shells, then crush them to 2mm, and put them into the continuous carbonization equipment through the auger equipment.

[0040] (2) soak the pulverized material obtained in step 1 in diamine hydrogen phosphate modifier with a concentration of 1%, and then dry it in a drum air dryer, and control the moisture at 15%.

[0041](3) Put the peanut shells treated in step 2 into the continuous biomass carbonization equipment. The material is pre-oxidized at 160°C in the upper area of ​​the equipment, and the water is volatilized, and then enters the middle area of ​​the equipment at a temperature of 300°C. Primary carbonization under oxygen conditions for 3 minutes; finally, further carbonization at 350°C for 10 minutes in the lower area of ​​the equipment. The carbonized material is continuously output in the auger equipment, and the atomized stabilizer is sprayed at the discharge p...

Embodiment 2

[0051] 1. The process of preparing peanut shell biochar is as follows:

[0052] (1) Air-dry the peanut shells, then crush them to 3.5mm, and put them into the continuous carbonization equipment through the auger equipment.

[0053] (2) soak the pulverized material obtained in step 1 in a modifier with a concentration of 5%, and then dry it in a rotary drum air dryer, and control the moisture content at 17.5%.

[0054] (3) Put the peanut shells treated in step 2 into the continuous biomass carbonization equipment. The material is pre-oxidized and volatilized at 185°C in the upper area of ​​the equipment, and then enters the middle area of ​​the equipment at a temperature of 330°C in anaerobic or oxygen-free Primary carbonization under the conditions for 10 minutes; finally, further carbonization in the lower area of ​​the equipment at 385°C for 12 minutes. The carbonized material is continuously output in the auger equipment, and the atomized stabilizer is sprayed at the outle...

Embodiment 3

[0064] 1. The process of preparing peanut shell biochar is as follows:

[0065] (1) Air-dry the peanut shells, then crush them to 5mm, and put them into the continuous carbonization equipment through the auger equipment.

[0066] (2) Soak the pulverized material obtained in step 1 in diamine hydrogen phosphate modifier with a concentration of 10%, and then dry it in a drum air dryer, and control the moisture at 20%.

[0067] (3) Put the peanut shells treated in step 2 into the continuous biomass carbonization equipment. The material is pre-oxidized at 200°C in the upper area of ​​the equipment, and the water is volatilized, and then enters the middle area of ​​the equipment at a temperature of 350°C. Primary carbonization under oxygen conditions for 15 minutes; finally, further carbonization at 400°C for 15 minutes in the lower area of ​​the equipment. The carbonized material is continuously output in the auger equipment, and the atomized stabilizer is sprayed at the discharg...

Abstract

The invention discloses a total nutrition carbon-based soil remediation fertilizer and a production method thereof and belongs to a carbon-based soil remediation fertilizer used for improving a soil environment and enhancing the maturity, yield and quality of flue-cured tobacco. The needs of nutritive materials in the crop growth process can be met, and conservation of soil quality is realized. The fertilizer mainly comprises the following components: 30-40% of biomass charcoal, 20-40% of a sesame seed cake fertilizer, 2-10% of a multi-element mineral fertilizer, 10-25% of humic acid and 15-25% of a composite fertilizer. In the fertilizer production process, key technologies such as biomass pyrolysis, cake fertilizer fermentation and the like are adopted, so that the effects of improving the C / N ratio in the soil, improving the quality and improving the aroma quality and aroma quantity of the flue-cured tobacco. The carbon-based soil remediation fertilizer disclosed by the invention is an optimal fertilizer for producing organic green agricultural products, can be widely applied to agricultural crops such as tobacco, fruit trees, corn, rice, sweet potatoes, watermelons, vegetables and the like and has important practical significance on agricultural sustainable development.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource development and soil improvement, and in particular relates to a full-quantity nutrient carbon-based soil restoration fertilizer and a production method. Background technique [0002] Soil is the basis for human survival and development. In recent years, the long-term and irrational use of new agricultural chemicals in my country's agricultural production and the increase of veterinary drug residues in livestock and poultry excreta have caused soil pollution to increase year by year, and soil fertility obstacles have become increasingly serious, directly affecting the normal growth of plants and the quality of agricultural products. . Therefore, the development of modern agriculture is facing serious problems of soil pollution and the quality and safety of agricultural products. [0003] At present, tobacco agriculture in the Mudanjiang area has problems such as large use of chemica...
