The use of mechanized production of organic tea can increase tea yield, quality and season. Putuo District, Zhoushan City, Zhejiang Province, after five years of mechanized production practice, has the ability to mechanized production of organic tea, mastered a set of organic tea production and processing technology. At present, it has been able to process Longjing Tea, Tianmu Qingding, Putuo Buddha Tea, Pearl Tea, Sencha, Tea Slices and other varieties, and produces various kinds of organic tea 73t. I. Mechanization of tea plantations Mechanized development of tea plantation requires the selection of flat or gentle slopes with concentrated contiguous, regular tea gardens, with a slope of no more than 15o, deep soil, 30 to 50 rows of plots, 1.5–1.8m of tea tree spacing, and a length of 50~ 100m; field head width is not less than 2 ~ 3m, field roads are connected by blocks, roads and roads are connected, suitable for mechanical passage. Tea gardens should be well drained and have the same layout. Second, tea plantation pruning and mechanization According to the production of tea plantations, tea tree mechanization pruning has a fixed trim, light trimming, deep trimming, heavy trimming and table cutting. 1. Stereotype pruning is mainly used to shape young tea trees to cultivate skeletons, promote branching, control crown height, and accelerate lateral expansion. The shrub-type tea trees are pruned twice a year after the age of two feet, and cut once each at the end of May and July, so that the tea tree and the main stem form 4-5 branches, making the tea tree skeleton as high as 40-50 cm. 2. Light trimming Lightly trim the tea plantations that have been put into production once or twice a year, after spring tea or summer tea picking. Use a single or double trimmer to cut the branches and leaves of the crown and cut out the protruding crown. 3. Deep pruning produces a large number of tea plantations in the tree crowns that have been put into production for many years, or in the case of severe cold or diseased insects. The deep pruning machine is used for crown reconstruction. After deep pruning, the skeleton height is maintained at 40-50 cm in summer. After tea picking is completed. 4. Heavy pruning works on tea gardens with a long tree age and decayed trees on the upper part of the tree crown. Cut off the aged tea tree from the ground by more than 20-25 cm from the ground with a brush cutter. After cutting, increase the organic fertilizer and re-cultivate it before the end of May to promote the new branch in early July. Germination before. After the summer tea was harvested from July to August, heavy shears were performed again. From the 35 to 40 cm above the ground, all were trimmed with a pruning machine. 5. Taiwanese cuts the tea trees that have died in the upper part of the canopy according to the growing conditions of the tea plantation, cutting all the old tea trees above 10-20 cm above the ground, re-shaping the canopies, usually in late autumn or autumn, and leaves them after the crown transformation. Peng, speed up the growth of new hair crowns. In the 2nd year after the cut, the Taiwan tea plantation is mainly cultivated. After the second year after the cut, it is pruned at heights of 35cm, 45cm and 50cm from the ground and put into operation in the third year. The mechanical picking was performed twice. The tea pickers had single and double pickers. The first round of spring tea was carried out when one bud and two leaves had been reached; the second round was carried out at the time of one bud three-leaf period after ten days. The ergonomics of tea picking on a single-person machine is 18 times that of artificial ones, but there are more heavy-cut and old-stemmed leaves. With the deputy head of the double machine, the workload of each tea picking up to 1650 kg per person. Should take the tea surface 15-20cm, cutting too high or too low will affect the quality of tea. The mature tea plantation was picked twice and completed once in a round trip. After the tea plantation tea plantation season is completed, it is required that the tea leaf surface leaven index should be more than 3 leaves, or the thickness of the canopy surface should be 10cm or more. With brush cutter operation, the labor rate can be increased by 2.5-4 times and the operation cost can be reduced by 30%. Second, tea processing mechanization technology into the processing plant fresh leaves should immediately be green, different grades, different varieties of fresh leaves should be green, rain leaves should be diluted, can not overlap, once per hour, fresh leaves should be spread on the bamboo On the mat, the thickness is 1-3cm, the booth requires a cool shade, free from sunlight, clean, air circulation, no peculiar smell, young leaves should be observed at any time, 4 to 12h with a fresh leaf weight loss rate of 10% -15% is appropriate . During the distribution process, lightly turn over properly to distribute water and heat evenly. After the fresh leaves have been fixed by a cleaning machine, a kneading machine, a tooth cutting machine, a strip machine, a wind sorting machine, a round sieve machine, and a dryer, the tea leaves are tightly knotted, curled uniformly, and their color is green and white. Tea production process is: 1 Longjing tea: fresh leaves - spread - to kill blue (Qing Guo) - Hui pot - quite head - finishing - warehousing. 2 days on the blue top: fresh leaves - spread - to kill - Ricoh - drying storage (6CHW series). 3 Putuo Buddha tea: fresh leaves - spread - killing - rub a frying - mention the millimeter - drying - warehousing. 4 Beads Tea: Fresh Leaves - Spreading - Fixing - Rubbing (150o6CR-265 rubbing machine) - Drying (6CPC-100CC dryer) - Pot (20kg/times) - Cauldron (40-50kg) - Cooling ( 12h) - Store in position. 5 tea processing technology: tea machine to trim, after picking 24 ~ 40cm long tea tree head - spread - chopped (5-10cm) - drying - rubbing - deblocking machine sifting - the remaining tea tree head dried - Crush into tea. Mechanized processing of tea tablets enabled tea tree heads to be used again, farmers increased their income, and at the same time achieved a second appreciation of tea production.
