利用茶叶气象平行观测资料综合分析法,分析春季茶叶生产与气象条件的关系。分析表明:春季土温5.0℃左右,茶树根系开始生长,平均气温7.0℃左右,早生茶树开始萌芽,一般品种8.0~10.0℃茶树开始萌动,18.0~23.0℃最适宜茶树生长,当气温降至8.0~10.0℃,茶芽生长停滞;进入体眠状态,春季茶芽萌动需要一定热量积累,早生品种需≥5.0℃的有效积温51.2℃开始萌芽,≥5.0℃的有效积温86.1℃进入萌芽盛期,春芽采摘期与积温关系式为y=78.6-2.335 2x+a;影响春季生产的主要气象农业气象灾害是倒春寒。
By using the comprehensive analysis method of parallel observation data of tea weather, the relationship between tea production and meteorological conditions in spring was analyzed. The results showed that the root temperature of tea plants began to grow at about 5.0 ℃ in spring and the average temperature was about 7.0 ℃. The early tea plants began to germinate. The tea plants of general varieties 8.0-10.0 ℃ started to germinate, while 18.0-23.0 ℃ was most suitable for the growth of tea plants. ~ 10.0 ℃, the growth of tea buds stagnated. When entering the body sleep state, the buds of spring tea buds need some heat accumulation, the effective accumulated temperature of ≥5.0 ℃ for early-growing varieties began to germinate, the effective accumulated temperature≥5.0 ℃ reached 86.1 ℃ and reached budding stage, The relationship between harvesting period and accumulated temperature is y = 78.6-2.335 2x + a; The main meteorological agricultural meteorological disaster that affects spring production is late spring cold.
