Control of main Diseases in shoot and Stem of Tea Plant
In order to effectively control tea plant diseases and insect pests, reduce pesticide residues in tea and improve tea quality, the main tea diseases and their control are introduced as follows. First, harmful symptoms 1. Tea bud blight: after the tea tree is susceptible to the disease, the bud growth is obviously hindered, affecting the yield and quality of spring tea, mainly harming one bud and three leaves of spring tea, first producing light yellow or yellowish brown disease spots on the leaf tip or leaf edge, showing irregular shape after expansion, the edge of the disease is obvious or not obvious; the bud tip is damaged in the shape of dark brown scorch, and the atrophy can not be extended.

Breeding techniques of improved Tea Variety
There are many methods to select excellent tea varieties, such as systematic selection, cross breeding, artificial breeding, introduction and domestication and so on. (1) systematic seed selection: also known as single plant seed selection. According to the breeding goal, a good single plant is selected from the seed selection materials, and the first single plant is propagated asexually, and compared with the standard species and the original population species, the excellent and good ones are cultivated into new varieties for propagation and promotion. Step: ① primary selection: according to the correlation between seed selection objectives and tea characters, several excellent individual plants were selected in the tea garden, marked and numbered for observation.

Key points of ecological cultivation techniques for improved tea varieties
1. Select the garden. Requirements to choose in good environmental conditions, surrounded by forest areas, mountains and water, fresh air, spring Qingqi, deep or fertile soil, slightly acidic, suitable for tea growth soil or soil, preferably fragrant lime soil. To think of good tea should be a unique geographical. 2. Land reclamation. First of all, clean up trees, shrubs and stones on the ground; second, remove roots, weed roots, bamboo rhizome roots, etc.; cultivate at a depth of more than 50 cm, perennial weed roots and rattan roots must be cleaned up,

Improved varieties and transplanting techniques of tea trees
1. Varieties suitable for making flat green tea: (1) Longjing 43: early hair teeth, strong cold resistance, high yield, but poor tolerance to high temperature, easy to develop leaf blight. It is suitable to plant flat tea in mountain areas and alpine tea gardens. (2) Wuniu early: early germination, strong tenderness, medium germination density, good quality of flat tea. (3) Pingyang extra early: sprouting early, growing strong, not blooming, making flat tea with green color, strong aroma and excellent quality. 2. Varieties suitable for making strip green tea: (1) Yingshuang: early germination, strong tenderness, long picking period and bud.

Tea tree cultivation should pay attention to matters
(1) The problem of tea tree shaping height. It is directly related to the transportation, utilization, absorption and consumption of nutrients in tea plants. It is generally believed that tea trees are low and good, and the appropriate tree height is between 60-70 cm. Minerals, inorganic salts, nitrogen, phosphorus, potassium and other nutrients from tea roots to branches, buds and leaves transport distance is short, fast, less consumption, nutrition concentration, high utilization rate. (2) The problem of keeping weeds. First of all, perennial firewood roots should be removed from the tea garden, such as the root whip of small bamboo, white hair grass roots, pig vine, wild grape, and the fruits of forest miscellaneous trees falling after maturity.

Tea tree type
The basic units of tea trees below species are divided according to the morphological characteristics, economic characters and geographical distribution of tea trees. The position of tea plant in the plant classification system is as follows: Angiospermae dicotyledonous class Dicotyedoneae, Camellia Theales, Theaceae Camellia Camellia, according to the international nomenclature and the study of tea characters, Camelliasinensis (L.) O.Kunt was determined.

Control of small green leafhopper with false eyes in tea plant
False-eyed small green leafhopper, commonly known as floating dust, is one of the main pests on tea trees in various tea areas of our province. Due to its harm, the light bud leaves are damaged, the yield is reduced, and the heavy bud leaves are destroyed, resulting in loss of harvest. 1. Morphological characteristics of the false-eyed small green leafhopper belongs to Homoptera, Cicadellidae. The whole life goes through three stages of egg → nymph → adult. 1. The egg is crescent-shaped, about 0.8 mm long and 0.15 mm wide, initially milky white, gradually turning light green, and a pair of red eye spots can be seen through the front end before hatching. 2. Nymphs total 5

Prevention and Control of several Diseases of Tea Plant
1. Tea cloud leaf blight is a common and serious leaf disease of tea trees. The disease is widely distributed in tea areas, the affected plants are often poor growth, new plants are not strong, bud head is thin, premature senility, seriously affecting the yield. The control methods of the disease are as follows: 1. Strengthen management and cultivate strong tea plants. Rational use of pesticides to avoid drug damage; timely ploughing and weeding, loosening the soil; doing a good job in draining the tea garden or resisting drought and cold, creating an environment conducive to the growth of tea trees, promoting the health of tea trees and improving their resistance

Occurrence characteristics and control techniques of black whitefly in tea plant
The black thorn whitefly mainly uses the larvae to absorb the tea tree juice on the back of the leaves, which causes coal bacteria parasitism and coal disease, and when it is serious, the tea tree is pitch black. The damaged tea trees had lower photosynthetic efficiency, lower germination density, late germination, thin bud leaves and serious defoliation, which not only affected the yield and quality of tea, but also seriously affected the potential of tea trees. 1. The occurrence characteristics of the insect occur for four generations a year, overwintering as mature larvae on the back of tea leaves, pupating in March in the second year, and the peak periods of the first to fourth generation larvae are in late May, mid-July, late August and September, respectively.
