Crush the branches to make organic mulch

Organic mulch (Mulch) is a new type of ecological and environmentally friendly surface covering material, and is also the mainstream landscape decoration material in large parks, green spaces, scenic spots, etc. It has the functions of ecology, environmental protection, energy saving and improving the living environment of plants. Crushing wood chips to cover the exposed surface can not only increase the organic matter content of the soil and improve soil fertility, but also prevent soil moisture from diffusing and evaporating to the surface, and retain water and moisture. At the same time, it can also slow down the surface runoff of rainwater, stagnate and store water, and conserve water sources. After covering with crushed wood chips, it can effectively control the rampant growth of weeds in the forest, promote the growth of trees, reduce the investment in manual weeding, and save management and maintenance costs. At the same time, after covering with crushed wood chips, it can effectively reduce the surface wind speed, block the topsoil, absorb and stagnate flying hair and catkins, dust particles, and reduce sand and dust. It has the reputation of a city vacuum cleaner.
