[Variety origin] Sichuan Agricultural University et al. selected and bred a single plant from 'Nanjiang Daye'. [Characteristics] Small tree type, large-leafed, medium-growing species. The tree posture is semi-open, strong growth potential, high branching site, dense branching. The leaf blade is upwardly inserted, moderately elliptic, with a length of 11.7 centimeters, a width of 5.1 centimeters, a green leaf color, and a sharp apex. The leaf base is obtuse, the leaf body is inflexed, the leaf surface is slightly elevated, the leaf margin is flat, and the serrations are sparse and shallow. In Nanjiang County, Bazhong City, Sichuan, the spring tea buds and leaves period in late March or early April, 5 days later than the control 'Fuding Dabaicha'. The buds and leaves have more luan hairs, and the germination density is medium. Tenderness is strong, germination is neat, buds and leaves are fat, easy to pick single buds, a bud of three leaves is 9.2 cm long, 100 buds weighing 68.8 grams. The blooming period is in the middle of November every year. Flowers sepals 5, hairy, petals white, 6, styles 3 split (shallow), ovary hairy, low fertility, flowers and fruits. The biochemical sample of one bud and two leaves of spring tea contains 18.2% of tea polyphenols, 4.1% of amino acids, 3.4% of caffeine, and 49.9% of water leachate. Suitable for green tea. The system of green tea, baking green tea, the cord is fat, more firm green, tender fragrance with fragrance, soup color green, taste is more fresh, strong and sweet, the leaf bottom is tender green and fat. The first growth cycle mu yield of one bud and two leaves 353 kg of fresh leaves, 10% higher than the control 'Fuding Dabaicha'; the second growth cycle mu yield of one bud and two leaves 394 kg of fresh leaves, 10% higher than the control 'Fuding Dabaicha'. It is susceptible to small green leafhopper and anthracnose. It has strong cold resistance and strong drought resistance in Sichuan tea area. [Suitable for planting area and cultivation technology points] Suitable for planting in Sichuan tea area. Due to the vigorous growth of this variety, the requirements for fertilizer cultivation conditions are high, it is appropriate to plant in the higher fertility of the soil. The variety of strong tenderness, pay attention to the prevention and control of mite damage, high mountain shady and humid tea area must also strengthen the prevention and control of tea cake disease. It is recommended to plant with early varieties.
