Formed mushroom dreg matrix block

Abstract

A formed mushroom dreg matrix block is prepared from the following raw materials in parts by weight: 70-90 parts of crushed mushroom dregs, 3-10 parts of macromolecular organic plastic particles, 3-5 parts of adhesive chemical short fibers, 3-5 parts of a nitrogen-phosphorus-potassium compound fertilizer and 3-5 parts of other nutrients. In the edible mushroom cultivation process, nutritional ingredients with high nitrogen content, such as bran, cottonseed hulls and soybean meal, and mineral substances, such as gypsum and magnesium sulfate, are added, mushroom dregs remained after edible mushroom cultivation are fully crushed by a crusher, the crushed mushroom dregs are put into a screening machine to screen out mushroom dreg fine powder with the diameter of 1-3 mm, the mushroom dreg fine powder formed after screening, the macromolecular organic plastic particles and the adhesive chemical short fibers are fully stirred at the high temperature of 150-300 DEG C, the mixture is pressed into a required block or container shape through a mold after being stirred while hot, a plurality of holes are formed in the surface of the matrix block, the matrix block is fully dried or air-dried after being cooled and shaped, and finally the formed mushroom dreg matrix block or container is formed.

Description

technical field [0001] The invention relates to the field of cultivation substrates for plants and edible fungi, in particular to a molded fungus residue substrate block. Background technique [0002] Substrate cultivation, the abbreviation of solid substrate cultivation plants, is a soilless cultivation method in which substrate (medium) is used to fix the plant root system and absorb nutrient solution and oxygen through the substrate. There are many types of substrates, commonly used inorganic substrates include vermiculite, perlite, rock wool, sand, polyurethane, etc.; organic substrates include peat, rice husk charcoal, bark, etc. The nutrient solution is supplied by drip irrigation. With the growth of people's living needs, the degree of urbanization is getting higher and higher, and the demand for urban residents to plant plants independently is increasing. Due to the lack of arable land in the city, especially the high density of living in the residential environment...

AI Technical Summary

Problems solved by technology

Now there are fungus residues used for plant cultivation, but most of them are in bulk, bagged or container cultivation, and the substrate is in a loose state and it is difficult to form a block and shape

On the other hand, the cultivation container made of fungus residue is difficult to directly connect with the root system of the plant, and other cultivation substrates need to be placed inside the container, which is not easy to carry. If the cultivation substrate in the container is loose, it is easy to drop slag, so it is not suitable for displaying. Tables for families and hotels (self-harvested and harvested) are not suitable for industrialized layered cultivation. There is no solution to the problem of easy slag drop of substrate blocks in the existing patents.

[0004] In the prior art, the patent number is: CN201811129736.3, which includes the following raw material components: 100 parts of decomposed sawdust fungus chaff; 2-5 parts of vermicompost; 0.1-0.3 parts of auxiliary materials; The particle size is ≤4mm; the auxiliary material is a mixture of polyacrylamide and biochar; the shape of this matrix is ​​not mentioned in this patent, there is no adhesive glue to make the bacteria residue form into blocks, and the matrix is ​​not easy to form and form into blocks It is not suitable for direct cultivation of plants or edible fungi; it needs to ferment the fungus residue (fungus chaff) before preparing the substrate, which is a heavy and cumbersome workload; the substrate of this patent is not convenient for large-scale mechanical operations, and the labor cost is high; the substrate of this patent It can only be used to grow vegetables and other plants, and cannot be used to grow edible fungi
