The early exploitation of spring tea and the provision of morning tea to increase the output value of spring tea production are the key to the increase of tea farmers' income. In combination with the reality of tea production in Fuyang City, the tea plantations are mainly used for fertilization, tea tree pruning, frost damage prevention, and tea plants before the exploitation of spring tea. Tea machine maintenance and other work.
1, shallow ploughing and fertilization. Through shallow ploughing, the soil can be loosened and the soil temperature raised, and early spring tea can be promoted. The shallow ploughing time is generally from the end of February to the beginning of March. Shallow ploughing combined with Shi Chuncha precipitating fertilizer, autumn and winter last year without basal tea plantation, spring tea precipitating fertilizer and basal fertilizer applied at the same time, depending on the amount of tea production, depending on the amount of tea production, the general annual production of 100 kilograms of famous tea tea garden use 300 kilograms Cake as base fertilizer, plus 50 kg of urea as topdressing. Fertilization time: early-maturing tea plantations were introduced before the end of February, and mid- and late-maturing tea plantations were introduced from late February to early March. Fertilization method: After shallow ploughing in the tea plantation, open the ditch (3-5 cm deep in the ditch) and apply it to cover soil to prevent loss of volatile fertilizer. Too dense tea gardens should be carried out before cloudy days and rainy days if they are thrown. Otherwise, the leaves of the tea trees and the loss of fat can be easily burned.
2, tea tree trim. For early mining, picking famous teas, general Chenglin tea garden will be pruned before the spring tea to prune after the spring tea, pruning time is generally conducted before May 20th, should sooner rather than later, otherwise affecting the growth of tea. For clonal mature young tea gardens, tea trees should be well-trimmed during the spring tea, and the tops of the tea trees should be topped with fixed cuts so that the canopy can be quickly cultivated to form a flat picking surface. Trimming method: The first shaping pruning is carried out when the tea seedlings are transplanted and planted, and the main branch is cut off at a height of 15-20 cm from the ground. The second pruning pruning is carried out at the end of February to early March of the second year after the tea seedling is planted. 30-35 centimeters away from the ground to cut flat, the third stereotyped pruning is carried out in the third year after planting, 45-50 centimeters away from the ground, spring tea supplemented by top mining, the general spring tea to leave the two leaves as well .
3. Beware of freezing injury in spring. The spring snow in March last year caused the early production of tea gardens in our city to be damaged. In particular, the Ukrainian early tea plantations suffered heavy losses. Therefore, the prevention of snow or freezing or the “cold spring” has become an important task during spring tea. Measures for prevention and control: (1) Covering the frost, covering the surface of the canopy and the tea line with rice straw, weeds, shading nets, mulch, etc. before the low-temperature cold wave arrives, and promoting the temperature rise of the tea garden and reducing the frost effect of the tea garden; the amount of grass planted is more than 1,500 kg per mu. It is advisable not to expose the ground; tea planters cover the weather at a temperature above 0°C or when there is sun. (2) Anti-frozen smoke is prepared by igniting a turf pile set on the edge of an inward-looking, well-behaved tea garden before the night cream comes, so as to diffuse smoke and reduce heat radiation at night, which can effectively prevent night cream from harming tea gardens. (3) Soil insulation, strengthening the management of fertilizer management in tea gardens, applying basic fertilizers, increasing the amount of custom soil, increasing the thickness of living soil layer, and establishing protective forest belts in the windward mouth of the tea plantation.
4, tea machine configuration and maintenance. Before the spring tea, we must do a good job in the tea factory machinery configuration, tea machine maintenance, plant cleaning and other work, to ensure that the tea processing has a clean environment to prevent pollution in the tea frying process.
