摘要
安吉白茶茶园早春气温垂直分布特征明显,茶园昼夜温差大,逆温天气频繁出现,凌晨5:00左右逆温最强,风扇高度与茶园冠层的温差达到了4℃;霜冻天气来临时,防霜风扇对茶园增温效果明显,茶园冠层平均最大增温2.8℃,能有效预防消除茶园霜冻害;每台茶园防霜风扇系统平均每年可减灾增收1922元/亩。
Vertical distribution characteristics of temperature of Anji Baicha tea garden was obvious. The diurnal temperature difference was significant and frost tended to happen in early spring. The temperature inversion was the most intense at dawn （05. 00）. The temperature difference between the site of blower and tea canopy was 4 ℃. Frost protective effects of the blower system for Anji Baicha tea garden was also obvious during frost weather season,and the mean of temperature was increased by 2.8 ℃ near tea canopy. Therefore,the blower system can effectively prevent frost damage. The blower system can reduce loss of 1922 yuan for one mu tea garden every year.
