How to produce high quality tea? Need to fertilize, trim and seal the garden
Tea is a long-established beverage raw material in China, with anti-inflammatory and anti-oxidation effects. And since ancient times, people's needs are special, with good economic value, can be brewed with tea or can be processed into skin care products, if the quality of good tea prices are tens of thousands. So how do you grow quality tea? The following small series will tell you that the tea garden science management technology hopes to help everyone.
(1) Deep turn: Generally, it should be carried out from the beginning of October to the beginning of November every year, with a depth of 15-20 cm. It is too easy to damage the root system and affect the normal growth of tea trees.
(2) Fertilization: Generally, farmyard manure or soil-fertilizer such as human and animal manure should be used. The application amount per mu is 2000 kg, and the tea trees are ditched and deep. It is conducive to the strong growth of tea trees, the leaves are thick, the quality is good, and the yield is improved.
(3) Pruning: Tea tree winter pruning is an important technical link to capture the high quality and high yield of spring tea. Pay attention to the fact that due to the tree structure, the vigorously growing tea tree can only cut off the protruding part of the canopy to achieve the flat surface of the canopy. Tea gardens with more delicate techniques and chicken claws are deeply trimmed and cut off branches 10-15 cm beyond the canopy. The old tea garden, where the tree is weaker and the yield is severely degraded, is heavily trimmed, and the height of the crown is cut from one-third to more than one-half. In order to prevent freezing damage, the northern tea area should be pruned in the middle and late May after the end of spring tea, and not trimmed in winter.
(4) Closing the garden: The wintering pests of tea trees mainly include small green leaf mites, tea mites, tea caterpillars and mites. It can be controlled by 0.7% lime half-quantity Bordeaux mixture or 0.3-0.5 Baume stone sulphur mixture. Spray the tea up and down, inside and outside when spraying.
(5) Anti-freezing: In the tea garden, more warm fertilizers such as cow manure and coke ash will be applied to increase the soil temperature. After fertilization, cultivate a new soil layer 8-10 cm thick at the base of the tea tree. Finally, the use of firewood, straw, manure, etc. to cover the intercropping and roots of tea trees can effectively increase soil temperature and maintain soil moisture. Reach early growth.
The main reason for planting tea gardens is pest control. Because too much medicine will lead to pesticide residues in tea, the quality will plummet, followed by strengthening tea garden management. The above is about the science of tea garden science management.
