Picking tea
Reasonable picking is one of the important measures for the stable production, high yield and high quality of tea. Rational tea-picking is based on tea varieties, climatic conditions, age, growth potential and different fertilizer and water levels, combined with market demand, picking tea, picking tea, and keeping and combining, both collecting tea and ensuring normal growth of tea plants and achieving sustained high yields. The purpose of quality. (1) The picking of young tea trees: Under normal fertilizer and water management conditions, the young tea trees after two shaping pruning can reach a height of 45 cm or more in the late spring tea, and after a third time shaping pruning, the tea tree is as high as about 60 cm. , can use "top to stay leaves" method. The criteria for adopting retention are spring tea leaves two or three leaves, one leaf for one or two leaves, two leaves for summer tea, one leaf for two leaves, one leaf for autumn tea, and one or two leaves for buds. In the process of young tea tree harvesting, attention should be paid to the principle of “cultivating the top and raising the edge, adopting high and low cultivation, and adopting thinning and thinningâ€. After three times of pruning and topping, the young tea trees that have been picked and preserved by leaves remain up to 60-80 cm in size, and when the tree reaches 130 cm, they can be managed with adult trees. (2) Picking of adult tea trees: Adult tea trees should adhere to the principle of “maintaining mining, combining mining and mining, and timely mining†so as to obtain higher economic benefits in a longer period of time. Spring tea is made of famous tea raw materials, mostly single buds, one bud, one leaf, or one bud and one leaf exhibition. If 5% reaches the mining standard, you can pick tea. The famous teas require delicate and even raw materials. Generally, one bud, one leaf, and one bud, one leaf, or single bud are picked. The bulk red tea, green tea, and red broken tea require medium tenderness, and the two are generally used for picking two buds and three leaves, and the tender leaves are used. Camellia and Liubao tea require basic mature shoots and two to three leaves. Generally, the method of “leaving fish leaves for the whole year†or “leaving fish leaves with spring and summer tea leaves, leaving one leaf for autumn tea, and timely, batch-wise, and adopting standard methods for picking†can be adopted. (3) Mechanical tea-picking: In recent years, tea-picking machines have been promoted in large-scale tea farms in China. There are two kinds of tea-picking machines: double stretcher type, mobile type, spiral hob cutting type, tea machine and horizontal rotary knife cutting type tea-picking machine. The picking machines of the two tea pickers are of good quality and convenient in operation, and can adapt to the operation of the tea gardens of various terrains, and improve the work efficiency by about 10 times as much as hand picking teas. In the trial promotion of tea-picking machine tea-picking tea plantation, its fertilizer training measures need to be properly strengthened. (4) Fresh leaf management: The fresh leaves collected are transported to the tea processing factory in time, and as soon as possible after acceptance by a specialist, they are placed in a clean, shaded room. Containers for transporting fresh leaves shall be made of bamboo baskets with good air permeability and cleanliness. The capacity of the baskets should be 50 to 100 kg, and it should be avoided during transportation to reduce damage. The general requirement is to enter the factory within 4 hours after picking the fresh leaves. If they cannot be sent to the tea factory in time, they must avoid the sun and the rain, put them in a clean and ventilated place, and then send them to the processing factory as soon as possible.
