一、山茶的环境和抗冻能力 1.抗冻能力地栽山茶抗冻能力较强。华东山茶在江南各地能在冰雪中越冬,可经受—8℃的严寒而无冻害;滇山茶在西南、中南地区也能在自然条件下越冬,可经受—5℃的气温,不受冻害。但气温骤降会导致冻害和夭折。盆栽山茶抗寒力较弱,一般在0℃以下就需要保温,大盆壮龄山茶也不得低于—3℃。
First, the environment and the ability of antifreeze 1. Antifreeze ability to grow stronger antifreeze tea. East China Camellia in the southern part of the Yangtze River in winter can winters, can withstand -8 degrees Celsius without freezing injury; Dian Shan tea in the southwest, south-central region can also be overwintered in natural conditions, can withstand -5 degrees Celsius, free from frost damage. However, a sudden drop in temperature can cause frost damage and premature death. Potted Camellia cold resistance is weak, generally below 0 ℃ on the need for insulation, large pots of tea age not less than -3 ℃.
