[Variety origin]: Systematically selected and bred from 'Lingyun White Hair Tea' in Guangxi by Guangxi South Subtropical Agricultural Science Research Institute. [Characteristics and properties]: Small tree type, large leaf type, mesophyll. The tree posture is semi-open, strong growth potential, branching part in, branching dense. The leaf blade is upwardly inserted, lanceolate, 13.5 centimeters long, 3.8 centimeters wide, with medium green color and sharp apex. In the Longzhou area of Guangxi, the exploitation period is generally in the middle of March, and the full bloom period of one bud and two leaves is generally in the middle of March; the germination density is high, with a lot of velvet; the length of one bud and three leaves is 6.8 centimeters, and the weight of one bud and three leaves in one hundred buds is 140.5 grams. The bloom period is in the middle and end of December every year. Spring tea bud two leaves biochemical samples containing tea polyphenols 21.6%, amino acids 2.8%, caffeine 4.0%, water leachate 49.1%, suitable for green tea. Baked green tea, tight shape, slightly curled, brown-green Phi Hao, yellow soup color is still bright, the aroma is still high, slightly tender fragrance fragrance, taste is more mellow, slightly astringent, the leaf bottom is thick, soft and even, there are buds green. The first growth cycle mu yield of one bud and two leaves of 450 kg of fresh leaves, than the control 'Fuding Dahao tea' 35% increase in yield; the second growth cycle mu yield of 706 kg, than the control 'Fuding Dahao tea' 35% increase in yield. Resistant to anthracnose, susceptible to small green leafhopper, strong cold tolerance, medium drought tolerance. [Suitable for planting area and cultivation technology] Suitable for planting in winter and spring in Guangxi with an average annual temperature of 20C˚, a minimum temperature of not less than -2C˚, a frost-free period of 350 days, and an average annual precipitation of about 1500 millimeters. Choose deep soil, organic matter-rich soil for self-arrangement, double rows of single-plant “zigzag” planting, mu planting about 4000 plants. Appropriate application of organic fertilizer, timely shaping pruning, batch leaf picking, picking and raising combination. Pay attention to the prevention and control of small green leafhopper.
