Tree root protection device for desert area

Abstract

The invention discloses a tree root protection device for a desert area. A biological layer, a feeding layer and a moisturizing layer are arranged in a grid body that is in a mesh support pocket shapefrom the top to bottom, and the biological layer is arranged at the topmost, the feeding layer is arranged at the lower part of the biological layer, the feeding layer is filled with nutritive filler, the moisturizing layer is arranged at the lower part of the feeding layer, and the moisturizing layer is filled with moisturizing filler. The device utilizes moss crust and tree branches and leavesas raw materials, and has high water absorption, high water retention rate and good biocompatibility. Nitrogen and phosphorus released from the nutrient filler can promote the growth of moss, and themoisturizing filler provides moisture conditions for the growth of moss crust. The presence and growth of moss crust can effectively regulate the earth surface microhabitat, increase soil stability and resistance to water erosion and wind erosion, greatly improve the physical, chemical and biological properties of the loose soil surface, avoid the sandification and exposure of tree roots, and effectively solve the problem of low vegetation survival rate in desertification areas.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a tree root protection device used in desert areas. Background technique [0002] Desertification refers to the degradation of the natural environment in arid, semi-arid or even semi-humid areas due to the combined effects of man-made and natural factors (including salinization, grassland degradation, soil erosion, soil desertification, desertification in a narrow sense, vegetation desertification, and sand dunes moving forward in historical periods. The general process of specific natural environment degradation marked by a certain environmental factor, such as invasion. The final result of desertification is mostly desertification. Desertification is one of the main ecological environmental problems faced by the world. The situation of desertification in China is even more severe. my country is one of the countries with severe desertification in the...
