Problems solved by technology

[0004] As a new type of urban greening surface covering material that has developed rapidly at home and abroad in recent years, organic coverings have been adopted in many garden projects, but currently widely used materials have some defects in performance and practicability, such as The mulch with fruit shell as raw material is not easy to decompose and has poor moisturizing performance; the mulch with pine phosphorus as raw material has a slow degradation rate and little effect on soil improvement; the mulch with bark as raw material has good heavy metal adsorption performance , there is the possibility of soil salinization; the mulch with wood as raw material has poor mixing ability with pigments and is not easy to color

preparation example Construction

[0022] The invention provides a method for preparing an organic covering, which comprises the steps of primary crushing, heavy metal adsorption, dyeing, secondary crushing and fermentation.

[0023] In the present invention, both the primary crushing and the second crushing steps are crushed by a remote-controlled crawler-type horizontal crusher, and the remote-controlled crawler-type horizontal crusher is a Peterson universal horizontal crusher. During the pulverization process, the remote-controlled crawler-type horizontal crusher will produce wire-like wood fibers, which can collude with each other to increase the mechanical strength of the organic covering, such as tensile strength and breaking strength, and prevent the organic covering from being washed by heavy rain. It can also save resources and prevent the waste of resources.

[0024] The raw materials used in the heavy metal adsorption process include organic acids and / or organic acid salts, and waste materials.

Abstract

The invention relates to the greening field of bare soil, and more specifically, the invention relates to a preparation method of an organic covering. The first aspect of the present invention provides a method for preparing an organic mulch. The preparation method of the organic mulch includes the steps of primary crushing, heavy metal adsorption, dyeing, secondary crushing, and fermentation.

Description

technical field [0001] The invention relates to the greening field of bare soil, and more specifically, the invention relates to a preparation method of an organic covering. Background technique [0002] Along with the raising of people's living standard, the landscaping of city seems more and more important, and the problem before people is the solution problem of bare soil. The exposed soil in the city not only affects the aesthetics, but also causes dust in windy weather and muddy walking in rainy weather. For this reason, we have specially developed organic mulch for urban greening. [0003] As a new type of environmentally friendly material, organic mulch can be described as a model of wood recycling. Organic mulch originated in the United States and has a history of nearly 30 years. It is a garden mulch product processed by collecting, crushing, screening, sterilizing, decomposing, and dyeing organic waste in the garden. It is laid around trees and other plants. The ...
