It is necessary to prevent the tea tree from "budding" after autumn.
The standing bud of tea tree refers to the phenomenon that the tea bud is not easy to grow, or the germination is delayed and the germination rate is low, and the new shoot is too small. When the tea plant sprouts, it is very conducive to the flower bud differentiation of the tea plant, resulting in a large number of camellias blooming from the end of October to the middle of November, which directly affects the growth of tea in the coming year and accelerates the aging of the tree. Therefore, it is very important to prevent the budding of tea trees. In order to prevent the tea tree from budding, the soil of the tea garden should be fully ploughed 3~5cm deep in summer and autumn, so as to cut off the soil capillaries.
