Evergreen-plant blown-sand-resistant wall, evergreen-plant blown-sand-resistant belt and biological tree house

Abstract

The invention discloses an evergreen-plant blown-sand-resistant wall, an evergreen-plant blown-sand-resistant belt and a biological tree house. Fine-variety Euonymus maackii is adopted herein; wood ofthe fine-variety Euonymus maackii has good toughness; reticular conjoined structure is used during planting; the reticular conjoined structure has very high strength after growing tall and thick; with the trees of Euonymus maackii growing tall and thick year by year, roots deepen underground, and higher strength guarantee is provided for a wall on the ground. The evergreen-plant blown-sand-resistant belt herein is composed of the evergreen-plant blown-sand-resistant walls in multiple rows, so that strength and blown sand resistance are further improved; evergreen trees of Euonymus alatus arewholly grafted to the reticular conjoined structures; with growth of the reticular conjoined structures, gaps in the reticular conjoined structures diminish gradually into small slits, and the dense branches and leaves of evergreen Euonymus alatus can fill the slits of the reticular conjoined structure, so that compactness of the walls is improved greatly at the premise that the walls have an evergreen function, and the walls gain good resistance to blown sand.

Description

technical field [0001] The invention belongs to the technical field of wind, sand and air filtering of garden plants, and in particular relates to a four-season evergreen biological anti-wind and sand wall, a biological anti-wind and sand belt and a biological tree house. Background technique [0002] The phenomenon of wind and sand refers to the phenomenon that a large amount of dust is carried by the wind and moves and spreads according to a certain path, causing the air to be cloudy and the visibility to be significantly reduced. The main manifestations of wind and sand disasters are: blowing and eroding soil, drifting sand burying cultivated land, villages, roads, railways and other engineering facilities, causing and aggravating land desertification, affecting transportation, causing air pollution, and destroying land resources and ecological environment. [0003] The barriers used in the existing anti-wind and sand technology are poplar windbreak forests. Because there...

Problems solved by technology

[0003] The barriers used in the existing anti-wind and sand technology are poplar windbreak forests. Because there is no conjoined body, the effect of anti-wind and sand and filtering air is poor; there are also pure inorganic materials (referring to steel structures, concrete, plastic products, etc.) to build high walls against wind and sand. For physical isolation, its inorganic materials cannot form a good integration with nature and the surrounding environment, and as time goes by, the inorganic materials will appear aging, damage, etc., making the use of inorganic materials to build high walls to physically isolate the wind and sand. The long-term effect is not good; there are also organic materials (referring to living trees such as paulownia, poplar) and inorganic materials (referring to steel structures, concrete, plastic products, etc.) Tree trunks such as tung tree and poplar can grow very high, which can make the walls of good wind and sand barriers very high, but trees such as paulownia and poplar have poor toughness, and generally can only be planted side by side in single or multiple rows. This planting method greatly reduces the strength of the anti-wind and sand barrier wall. At the same time, the gaps between the trunks are filled with inorganic materials. The combination of organic materials and inorganic materials will appear poorly as the trees grow. , seriously affect the anti-wind and sand effect and the later maintenance is very inconvenient. In addition, trees such as paulownia and poplar cannot be evergreen in all seasons, and they cannot be grafted to achieve evergreen in all seasons, which is not conducive to the integration with nature and the surrounding environment.
