茶树不正常新梢也叫茶树“对夹叶”。它是节间相对缩短了的顶芽休止的低级嫩枝。这类嫩枝芽头小,叶质硬,特定化学成份含量低,是实现制茶原料优质化的一大障碍,也是目前生产中尚未解决的主要难题。为了摸索这类不正常新梢的发生规律,从而控制其早发多发,我国茶叶科技工作者对此进行过不少研究,但至今尚未统一认识。本所从1981年开始对产生这种不正常新梢的多因素进行了正交试验,现将初步试验结果报告于后:
Tea tree is not normal shoot also called tea tree “folder leaves.” It is a low-grade shoot that terminates in a relatively shortened internode. Such shoots with small buds, hard leafy leaves and low content of specific chemical components are a major obstacle to the quality of raw materials for making tea and are the main unsolved problems in the current production. In order to explore the law of occurrence of such abnormal shoots, and thus control its multiple occurrences, many tea technologists in our country have done a lot of research, but so far no unified understanding has been reached. Since 1981, our institute has conducted orthogonal experiments with many factors that produce such abnormal shoots. We report the results of the preliminary tests later:
