由于操作不当,幼龄茶树低部位的休眠芽和新抽嫩梢因接触除莠剂如百草枯的飞溅而受损害,从而耽误茶树的树冠伸展,增加了植株高度,延迟了茶树的发育。如果预防不当,则正常高度范围内65％的潜伏芽被喷洒飞溅的药剂损害。建议接触除莠剂在幼年茶树限制使用,直到长出几条健壮侧枝为止。在此期间可用人工耕作控制杂草或用萌前除莠剂如西玛津。
Due to improper operation, the young buds of the lower part of the young tea buds and new shoots due to exposure to herbicides such as paraquat splash damage, thereby delay the crown extension of tea, increased plant height, delayed the development of tea. If not properly prevented, 65% of the latent buds in normal height are damaged by spray splashes. It is recommended that exposure to herbicides be restricted to young tea plants until a few robust branches grow. Artificial tillage may be used to control weeds or preemergence herbicides such as simazine during this period.
