Suitable conditions for growth of tea trees
The shape of heat is generally expressed by temperature, while the main factors affecting the growth of tea trees are air temperature and soil temperature. The biological lowest temperature of tea plant is generally about 10 ℃ (growth threshold temperature). The early bud species are less than 10 ℃, while the late bud species are higher than 10 ℃. The optimum temperature for the growth of tea trees refers to the most vigorous and active temperature of tea trees, which varies with different varieties and producing areas, mostly 20 ℃ ~ 30 ℃. The temperature difference and the temperature difference between day and night directly affect the accumulation of photosynthetic matter. The temperature is high during the day, and the light and matter are combined.

Cutting Propagation of Tea Plant
Tea trees can be propagated by seeds or vegetative organs such as stems, leaves and roots for asexual reproduction (or vegetative reproduction). There are many methods of asexual reproduction, such as cutting, striping and so on. The method of asexual reproduction is mainly short-spike cuttage. Most tea varieties have the ability of both sexual and asexual reproduction. Asexual reproduction can protect the excellent characters of tea varieties, and the offspring have the same characters and high reproduction coefficient. However, there are many flower workers, the cost is high, and the requirements of seedling cultivation and management are high. 1. Cutting rooting

Tea tree picking technology
(2) Tea picking: the object of tea picking is the new shoot, which is the main nutritional organ of tea tree and the "factory" for tea tree to produce nutrients. in order to solve this contradiction, the key is to carry out reasonable picking. Reasonable picking is to correctly solve the relationship between picking and retaining leaves according to the growth characteristics of tea trees. Through picking, we can achieve the combination of increasing yield and improving quality, increasing production in the same year and season and prolonging the economic age of tea trees. Tea picking should master the following links. 1. In accordance with the standards and

Tea cake disease harms tea tree growth
Tea cake disease, also known as blister leaf blight and leaf swelling disease, is an important disease on tender shoots and leaves, distributed in various tea areas throughout the country, mainly damaging tender leaves, tender stems, new shoots, buds, fruits and petioles. Young leaves infected with the disease initially appear pale yellow to reddish brown translucent small spots, and then expand into a circular spot with a diameter of 0.3~ 1.25 cm. The front of the spot is depressed, light brown to dark red, and the back is raised. It is a steamed bun shaped blister with gray or pink or gray powder on it. The powder disappears in the later stage, and the raised part shrinks to form brown withered spots. There is a round spot around the edge.
