Abstract

The invention discloses a ground covering material based on king grass and a preparation method thereof, and belongs to the technical field of ground covering material preparation. The preparation method comprises the following steps: (1) drying king grass and crushing it into pieces with a length of 2 to 3 cm (2) add livestock and poultry feces to the pretreated Wangcao and ferment to obtain a fermented slurry; (3) after the fermentation is completed, add a natural antibacterial agent to the fermented slurry to obtain a mixed slurry Then the mixed slurry is put into the liquid spraying machine, and the liquid spraying machine sprays the mixed slurry to the surface, and after drying, the ground covering material based on Kinggrass is formed. On the one hand, the invention can reduce the use of chemical raw materials such as polyethylene, and reduce the pollution of chemical raw materials to farmland;

Description

technical field [0001] The invention relates to the technical field of preparation of ground covering materials, in particular to a ground covering material based on king grass and a preparation method thereof. Background technique [0002] Surface covering materials have multiple functions such as significantly increasing ground temperature, enhancing sunlight, water retention and drought resistance, etc., enabling crops to fully and effectively utilize light, heat resources and water, and achieve early maturity, high yield and high quality. In the 1980s, my country began to promote the technology of surface covering materials, which promoted the transformation of agricultural production methods. However, the extensive use of surface covering materials has not only achieved good economic benefits, but also caused serious white pollution. The surface covering materials left in the soil have caused serious harm to the soil environment and crop growth and development. In rece...
