Effect of Wet damage on the growth and Development of Tea Plant
Tea trees require moist air conditions, but they are not resistant to excessive soil moisture. Excessive soil moisture and even stagnant water on the ground hindered the respiration of roots and reduced the ability of absorbing water and fertilizer, which seriously affected the growth of bud leaves and reduced the yield and quality of fresh leaves. When the root is asphyxiated seriously, the anaerobic microorganisms are active, and organic acids are produced to poison the tea root system, resulting in peeling, necrosis and decay. The wet damage of tea plant is shown as follows: few absorbing roots, short lateral roots, shallow root layer, and some lateral roots extend horizontally or even upward instead of downward. Suffer severely

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.
