设置防风障 冬季在桔园的当风面,与风向成垂直方向设置防风屏障,高度超出桔树高度。按每隔风障高度的4～5倍距离设障一道,能有效地缓和风速。据测定,一般可减少风速40％左右,提高小区气温0.2～0.8℃,严寒期增温1.6℃,增高土温0.2～1.5℃。下雪期,可减少积雪厚度,显著地减少冻后落叶。
Set the weather barrier winter when the wind in the orange orchard, with wind direction into the vertical direction of the wind barrier, height exceeding the height of orange trees. According to every 4 ~ 5 times the height of the wind obstacle obstacle barriers, can effectively ease the wind speed. According to the determination, the wind speed may be reduced by about 40%, the temperature of the community is raised from 0.2 to 0.8 ℃, the temperature is raised to 1.6 ℃ during the cold period, and the soil temperature is increased from 0.2 to 1.5 ℃. Snow, can reduce the thickness of snow, significantly reduce the frozen leaves.
