Wind barriers can make full use of solar energy and improve the ground temperature and air temperature in wind barrier protection areas. In winter, the physiological changes of plant branches are mainly affected by low temperature environment. After the wind barrier is set up in plants, the physiological indexes in plants will inevitably change due to the change of microclimate conditions.
Wind shields are generally made of grass curtains, non-woven fabrics, striped fabrics, plastic sheets, sun visors, etc. In the past, they were usually woven from materials such as reeds, sorghum or corn stalks. Among these materials, the grass curtain has the best water permeability, the strongest wind resistance and the highest bearing capacity. For gardens without special requirements, grass curtains are generally used to build windbreaks.
It can not only block the cold wind, reduce the wind speed, prevent the wind from drying plants, reduce the death of seedlings due to water drying, but also increase the snow, which is beneficial to keep the soil water evaporation and leakage and prevent spring drought.
Plants should be watered immediately after the windbreak is completed. On the one hand, it can prevent plants from freezing after water shortage in winter. On the other hand, high specific heat of water and sufficient moisture are beneficial to soil insulation. After the wind wall is removed, water the plants immediately, so that the plants can quickly take root and sprout and resume growth.
Setting up a road wind barrier can change the lateral force of vehicles, create a local environment with relatively low wind speed for vehicles in a strong wind environment, effectively reduce the wind load of vehicles and improve the safety of vehicles under the action of crosswind, which is the most effective technical measure to solve the crosswind of vehicles at present.
The road wind wall developed by Shangfeng Technology Co., Ltd. makes full use of the principles of engineering meteorology, fluid mechanics, aerodynamics and wind measurement technology, and sets different types of wind blades in the dominant wind direction. When the strong wind passes through the "wind barrier", there will be two phenomena of separation and attachment behind the wind barrier, forming an upper and lower interference airflow.
The kinetic energy of the incoming wind is lost, thus reducing the wind speed of the incoming wind, achieving the purpose of accurately controlling wind energy and restraining strong wind, and ensuring the driving safety of vehicles. At the same time, the vortex wind direction of the train is blocked by the "wind barrier", which reduces the kinetic energy of the vortex wind and its influence on the surrounding environment.
