Method for manufacturing mildew-proof organic covering

Technical Field

The invention relates to the field of biological resource development and environmental protection, in particular to a method for manufacturing a mildew-proof organic covering.

Background

The organic covering is made of trunk and thick branches in the green plant wastes as raw materials, and has the functions of preserving heat, retaining water, inhibiting weeds, reducing plant diseases and insect pests, increasing fertilizer, retaining dust, preventing soil hardening, preventing water and soil loss, beautifying the landscape and the like.

The organic covering can be applied to greenbelts, parks, roads, amusement places, home gardening, pot culture and the like, and has important application value in future urban construction. Along with the rapid development of China, the yield of urban garden greens is also increased year by year, and the problem of consumption and treatment needs to be solved urgently.

Mold is a species of fungus that lives in a parasitic or saprophytic manner.

When growing on a solid substrate, part of the hyphae penetrate into the substrate to absorb nutrients, and are called substrate hyphae or nutrient hyphae; aerial hyphae can further grow into reproduction hyphae to produce spores. A large number of mycelia are interlaced into villous, flocculent or reticular forms, called mycelia, which are usually white, brown, gray, or vivid colors, and some of them can produce pigments to color the substrate.

The traditional organic covering directly dyes the green plant wastes after being crushed, and the organic covering prepared by the method has poor stability and is easy to mildew during stacking or bagging storage. The quality of the mildewed organic covering is unqualified, and the landscape effect of paving is influenced.

Therefore, the improvement of the stability of the organic covering and the prevention of the mildew of the organic covering during stacking and storage are technical problems to be solved in the field.

Detailed Description

The technical solution of the present invention will be described in detail with reference to specific examples.

The invention provides a method for manufacturing a mildew-proof organic covering, which comprises the following steps:

(I) raw material collection

The raw materials comprise green plant wastes, and a plurality of garden waste collection points can be set in different towns to scatter and collect the green plant wastes so as to be treated in a centralized manner.

(II) pulverizing and sieving

Crushing the branches and the like in the collected green plant wastes twice by using a crusher, wherein the first time is coarse crushing, and the large-volume coarse branch green plant wastes can be crushed into wood blocks; the second time is fine crushing, and the wood blocks obtained by coarse crushing can be crushed into wood blocks with the particle size of 1-10 cm; and (4) after crushing, passing through a sieving machine with a pore of 3cm to obtain the organic covering material.

(III) thermal fermentation treatment of raw materials
