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.
