[Variety Source] Hongya County Guanyin Tea Specialized Cooperative and others selected from a single plant of 'Sichuan Zhongxiaoye'. [Characteristics and properties] Shrub type, medium leaf type, early growing species. The tree posture is semi-open, strong growth potential, low branching site, dense branching density. The leaf blade is upwardly inserted, the shape of the leaf blade is narrowly elliptic, the length of the leaf blade is 9.6 centimeters, the width is 4.0 centimeters; the color of the leaf is green, and the shape of the apex of the leaf blade is sharp. The exploitation period is usually in late February, and the full bloom period of one bud and two leaves is usually in mid-March; the germination density is high, with less velvet; the length of one bud and three leaves is 5.3 centimeters, and the weight of one bud and three leaves in one hundred buds is 27.2 grams. Blooming period is in the middle of October every year, the inner whorl of petals is white in color, with 5-6 petals, the diameter of corolla is medium (3.7 cm), the ovary has velvet hairs, the density is medium, the stylar division position is high, and the pistil is lower than the height of the stamen. The biochemical sample of one bud and two leaves in spring contains 18.8% of tea polyphenols, 5.3% of amino acids, 3.4% of caffeine, and 41% of water leachate. Suitable for green tea and black tea. Green tea, tight green with hair, chestnut aroma rich and persistent, bright green, fresh and mellow flavor; black tea, tight and more moist with golden hair, sweet aroma, orange-red bright, mellow flavor. The first growth cycle mu yield of one bud and two leaves 369 kg of fresh leaves, than the control 'Fuding Dabaicha' 2% increase in yield; the second growth cycle mu yield of one bud and two leaves 339 kg of fresh leaves, than the control 'Fuding Dabaicha' 2% yield reduction. It is resistant to small green leafhopper, anthracnose, and cold resistance. [Suitable for planting area and cultivation technology] Suitable for planting in the spring and fall of Sichuan tea area in the southwest ecological zone. Double rows of single or double planting need to be 3 times after the stereotypes pruning, the variety of strong growth potential, suitable for planting in the fertility of medium or high soil, strengthen the fertilization management; early spring attention to prevention and control of aphid infestation.
