“The green tea leaf has a short growing period, high temperature, fast growth, well-developed cell tissue, high cellulose content, and easy aging of the leaf quality. It should be tender and tender.†August 1st, Dadukou Zhenchuan, Naxi District, Ganzhou City Tsang Maolin, director of the Dragon Tea Association, came to the tea plantation of the members and guided the villagers to conduct scientific picking. He said that tea plants can be harvested several times a year, and tea picking in the current season has an impact on bud germination, yield, and quality in the next season, and picking in that season will have an effect on the growth and development of tea in the next year or even longer. Because of the impacts on production and quality, it is imperative to attach great importance to rational scientific tea picking in order to ensure the normal growth of tea plants and achieve sustained high yield and quality.
Picking of young tea trees
The picking of young tea trees should be conducted in accordance with the principle of “maintaining as the mainstay, supplementing mining as the supplement, keeping the height of the harvesting low, keeping more and less mining, and adopting the canopyâ€.
Under the normal fertilization and water management conditions, the young tea trees after two shaping and trimming can reach a height of 45 cm or more in the late spring tea. After the third shaping, the tea tree can reach as high as 60 cm. The method of picking tea. The criteria for adopting retention are spring tea leaves two or three leaves, one bud for one or two leaves, two leaves for summer tea, one or two leaves for one bud, 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.
Picking of adult tea tree
Adult tea trees should adhere to the principle of “maintaining mining, combining mining, and mining in a timely manner†to achieve higher economic benefits in a longer period of time. Specifically, it should be determined based on the natural environment, climate season and cultivation conditions of each place.
Old tea tree picking
Leaves must be different depending on the tree vigor and the degree of aging and different methods of tea picking. For the decline of the physiological mechanism, photosynthesis is weakened, the budding power is reduced, and the buds are small. For the aged tea trees with a large number of clips, leaves should be left as appropriate when picking; the tree vigor can generally be determined by the method of the adult tea tree.
Older tree vigor can adopt the method of centralized retention, that is, stop the collection for one season and allow them to recover after the growth.
Picking of aging tea tree
Need to implement heavy pruning or regrowth to update the canopy, because the tea tree is re-pumped, and it can be started by the method of topping the young tea tree; when it is in the second and third years, it needs to be retained and left, and the combination of leaving 3 leaves and leaving 1 leaves is needed. Picking method; when the crown is up to 70 cm or more and the awning is more than 100 cm wide, the adult tea tree can be picked.
Morning, afternoon, and evening green are separate
There are dew on the leaves of the early morning, the morning sun is weak, the water is not easy to evaporate, the water content of the shoots is high, and the leaves are very hard and brittle; the afternoon sun is blown by the breeze, the sunlight irradiates, the water evaporates more, the bud contains With less water and soft leaf quality, it is a raw material for making high-grade tea. Due to the decrease of sunshine intensity and the increase of water content, there is no sunshine drying. Therefore, early morning, late afternoon and late night must be separated. Different measures must be taken in order to achieve the best results.
The bud size should be separated
When the same tea plantation is harvested, it is not suitable to pick it up once, and it can be picked three times. When picking, you should keep the “fish leaf†culture groves. The first time you pick the earliest open face, open the face after two days of harvest, and finally pick the strongest bud. Because of the large disparity in the size of their leaves and buds, the differences in water and other inclusions are also large.
Different practices should be adopted in the greening process such as sun drying and shaking green so as to avoid the consequences of uneven fermentation and poor quality.
Fresh leaf care needs to be timely
The fresh leaves that are harvested are transported to the tea processing factory in time, and they are spread out in a clean, shaded room as soon as possible after acceptance by a specialist. Containers for transporting fresh leaves are made of bamboo baskets with good air permeability and cleanliness. The capacity of the basket is 50-100 kg, and it is avoided during transportation to reduce the 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.
