Using wind-breaking flowers is safer for winter
The wind barrier is the use of a variety of tall stalks of stalks planted into a fence-type facility to block the cold wind, increase the local temperature and humidity, to ensure safe winter flowers and trees. The wind barrier has a significant windproof effect, which makes the airflow near the wind barrier relatively stable and can reduce the wind speed by 10% to 15%. In addition, the higher the wind speed, the more pronounced the windproof effect. Generally, winds of Grades 5 and 6 can be turned into a level 2 or 2 wind before the windbreak. The wind barrier can make full use of the radiant energy of the sun to increase the ground temperature and temperature of the wind barrier protection area. Because the wind barrier increases the area of ​​protected solar radiation, the sun's radiant heat spreads in front of the wind barrier. In addition, because the airflow is relatively stable, the temperature before the wind barrier is also easy to maintain. It has been determined that the general wind-barrier temperature is 2°C to 3°C higher than the nighttime temperature, and 5°C to 6°C higher during the daytime. The effect of windbreak warming was most pronounced on sunny days, followed by no wind and sunny weather, but not on cloudy days. Generally, the higher the temperature is, the closer the protection zone is to the wind barrier. Wind barriers also have the effect of reducing moisture evaporation and increasing relative humidity, which can form a good small environment. In northern China, where winds are sunny and windy in winter and spring, the development of wind barriers has a good moisturizing effect. China Agricultural Network Editor
