Embodiment 1

[0035] Mix the eucalyptus bark and fiber raw materials for the first time to obtain the primary powder, spray the fermentation liquid on the primary powder, add water, and undergo secondary fermentation to obtain the fermented material. The fermented material is crushed for the second time and sieved Divide the re-powder material, which can be made into semi-substrate fertilizer;

[0036] Wherein, the fermentation bacteria liquid is composed of fermentation bacteria and nutrients, and the nutrients are composed of the following raw materials by weight components: 1 part of urea, 80 parts of rapeseed bran, and 5 parts of molasses concentrate .

Embodiment 2

[0038] The eucalyptus bark and fiber raw materials were mixed for the first time to obtain the primary powder, and the fermentation bacteria liquid was sprayed on the primary powder, and the humidity was adjusted to 50% after adding water, and the fermented material was obtained through secondary fermentation. After the second crushing, the re-powder is sieved, and the re-powder can be made into matrix fertilizer;

[0039] Wherein, the fermentation bacteria liquid is composed of fermentation bacteria and nutrients, and the nutrients are composed of the following raw materials by weight components: 3 parts of urea, 85 parts of rapeseed bran, and 8 parts of molasses concentrate .

Embodiment 3

[0041] The eucalyptus bark and fiber raw materials were pulverized for the first time and mixed to obtain the primary powder, the fermentation bacteria liquid was sprayed on the primary powder, and the humidity was adjusted to 60% after adding water, and the fermented material was obtained through secondary fermentation. After the second crushing, the re-powder is sieved, and the re-powder can be made into a semi-substrate fertilizer;

[0042]Wherein, the fermentation liquid is composed of fermentation bacteria and nutrients, and the fermentation bacteria are composed of Aspergillus niger, actinomycetes, Bacillus megaterium, yeast with a mass ratio of 4:2:3:2:2:3:1 , Trichoderma viridans, Phanerochaete chrysosporium, and Pleurotus ostreatus, the specific preparation method of the fermentation bacteria is: take out the plastic frozen storage of 7 kinds of bacterial strains from the -70 ℃ refrigerator Put the tube into a constant temperature shaker at 40°C with a rotation speed ...

Abstract

The invention discloses a recycling high-value utilization technology for eucalyptus barks. The technology comprises the following steps: respectively primarily crushing the eucalyptus barks and a fiber raw material, mixing the crushed eucalyptus barks and fiber raw material to obtain a primarily crushed powder, spraying a fermentation bacterium liquid on the primarily crushed powder, adding water, carrying out secondary fermentation to obtain a fermented material, secondarily crushing the fermented material, screening the crushed fermented material to obtain secondarily crushed powder, and preparing a semi-matrix fertilizer or a matrix fertilizer from the secondarily crushed powder. Phenol allelochemicals in the eucalyptus barks are degraded through a fermentation technology to make the eucalyptus barks become an economic resource to be used, cassava bagasse, peanut shells, traditional Chinese medicine residues, mushroom residues and other wastes are added to reduce the product cost,and a fluffed material is obtained in a physical way which is fluffing treatment of the secondarily crushed material with a crusher, so substance and structure change caused by a chemical swelling agent is avoided, and the economic and practical properties of the product are highlighted.

Description

technical field [0001] The invention belongs to the technical fields of utilization of agricultural and forestry resources and chemical engineering, and in particular relates to a high-value resource utilization process of eucalyptus bark. Background technique [0002] According to statistics, in 2017, the total forest area in Guangxi was 217 million mu, ranking sixth in the country, and the forest coverage rate was 62.28%, ranking fourth in the country. Among them, the planting area of ​​eucalyptus reached 30 million mu, ranking first in the country, and the timber resources are very rich. . The amount of eucalyptus bark produced in the process of wood processing can reach 7.5 million cubic meters per year, which is rich in eucalyptus bark resources, but eucalyptus bark contains a special phenolic allelochemical, which directly covers the roots of crops and will inhibit the root system of crops Growth and development, stacking near water will pollute water sources, and wit...
