1991年12月下旬湖北武昌金水地区连续低,温最低温度-10℃,茶树叶片普遍出现不同程度冻害。我省多数地区轻修剪都在早春,重修剪和台刈多在五月中旬。也有少数地区采取晚秋修剪。在不出现冬旱和连续低温的情况下,晚秋修剪看不出有什么坏处,但若遇冬旱或连续低温,就显得得不偿失了。笔者对晚秋修剪和不修剪茶园进行了冻后叶片受冻程度的调查,试作统计分析,权衡利弊,为正确把握修剪时期,提供依据。
In late December 1991, Jinshui, Wuchang, Hubei Province, continuous low temperature lowest temperature -10 ℃, tea leaves generally appear different degrees of frost damage. Most areas in our province light pruning are in early spring, heavy pruning and Taiwan Kariya in mid-May. There are also a few areas to take late autumn pruning. In the absence of winter drought and continuous low temperature, the late autumn pruning can not see any harm, but in case of winter drought or continuous low temperature, it seems worth the candle. The author of the late autumn pruning and non-pruning tea leaves frozen degree of freezing of the investigation, trial statistical analysis, weighing the pros and cons, to grasp the pruned period, provide the basis.
