After weeding and weeding and chasing and weeding the tea plantations, the surface of the soil is generally firm after harvesting. At the same time, the weeds in the tea plantation in the autumn are growing vigorously. Therefore, it is necessary to carry out a shallow tillage in combination with topdressing after summer tea, and the topsoil is shallow. Cutting the soil capillary can both suppress and reduce weed growth and loosen the topsoil. For young tea gardens, it is emphasized that as much as possible, beech grass, pond grass, straw, straw, etc. should be covered in the whole park to prevent weed regeneration, reduce soil temperature and water evaporation, prevent flooding and soil erosion, and increase soil organic matter. All have a significant effect, generally about 1,000 kilograms covered. The amount of topdressing of autumn tea should account for 20% of topdressing for the whole year, and quick-acting fertilizer is the mainstay. Generally, about 20 kg of urea is applied to the Maturation Tea Garden to increase the yield of autumn tea. For the newly-established tea gardens, the thin human feces and urine should be drenched beside the tea seedlings, and a small amount of chemical nitrogen fertilizer should be added, which can not only moisten the soil but also strengthen the whole seedlings.
Miaomiao Miao, planting green manure for the new development of tea gardens, due to drought and other reasons, the survival rate decreased, resulting in lack of crop ridges, can be planted in the late autumn season planting tea plantation specifications re-fill the seedlings, pouring enough rooting water to ensure survival. In order to enhance the ability of young tea seedlings to resist normal drought and defrost and increase soil organic matter, the autumn and winter green manures can be interplanted among large tea plantations, and they can be greened in early April of the following year. The winter green manure is mainly a bean crop, such as peas, fertile radishes, broad beans, and milk vetch, etc., which can be combined with late autumn tea plantations and deep plowing. Seeds are planted from late September to early October. High mountains are planted slightly earlier to facilitate seedling growth. Growing safely and overwintering, pay attention to planting winter fertilizer, apply some fertilizer between the tea rows, use small fertilizers to grow large fertilizers, apply fertilizer for spring fertilizer before sowing, and raise the seedlings with a small amount of nitrogen fertilizer to increase the yield of green manure.
Batch mining, refined tea should be based on the local tea garden climate characteristics and market conditions, timely, batch, leave leaves picking, with the mining with the transport, Qin mining more system Qiujie tea, autumn Longjing, Qiu Maofeng and other high-end autumn tea, Increase the proportion of famous autumn tea. Attention should be paid to proper tender mining, fish leaf mining, and retention and conservation. The harvest can be harvested until mid-October. If the drought is severe or the tree vigor is weak, use less land and close the park in advance. For young-age harvesting gardens, the use of top-covering and re-cultivation are mainly supplemented by tender mining; the adult tea gardens are mainly harvested; the tea gardens are rejuvenated, and the cultivation is mainly adopted, and the tree crowns are collected and cultivated.
Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
