[Variety origin] Selected by Tea Research Institute of Sichuan Academy of Agricultural Sciences et al. from a single plant of 'Sichuan Zhongxiaoye'. [Characteristics] Shrub type, medium leaf type, early growing species. The tree posture is semi-open, strong growth potential, low branching site, dense branching. The leaf blade is upwardly inserted, moderately elliptic, 10.6 centimeters long, 4.3 centimeters wide, green in color, with a sharp apex. Mining period is generally in early March, one bud and two leaves in full bloom is generally in mid-March; germination density is high, buds are fat, heavy and solid, velvet hairs are many, holding tenderness is strong, one bud and three leaves 100 buds weighing 38.1 grams. The blooming period is in the middle of October every year. The biochemical sample of one bud and two leaves in spring contains 20.6% of tea sound, 2.8% of amino acid, 4.3% of caffeine, 45.4% of water leachate. Suitable for green tea. Green tea production, the appearance of the color and lustre of young green oily, cord strong, tight, hidden hair, there is a peak seedling, soup color of young green and bright, the aroma of young fragrance with floral, taste mellow and sweet, the bottom of the leaf is yellow-green and bright. The first growth cycle mu yield of one bud and two leaves 166 kg of fresh leaves, than the control 'Fuding Dabaicha' 31% increase in yield; the second growth cycle mu yield of one bud and two leaves 195 kg of fresh leaves, than the control 'Fuding Dabaicha' 39% increase in yield. Resistant to tea anthracnose, resistant to tea leaflet green cicada, drought resistance, heat resistance is slightly poor. [Suitable for planting area and cultivation technology points] Suitable for planting in Sichuan tea area in spring and fall. Select robust tea seedlings, double rows of single plants or double rows of double plants staggered nest planting, planting early for shading treatment, complete the 3 times stereotypes can be put into production after pruning. Drought resistance, heat resistance is a little poor, should strengthen the fertilizer management, tree regulation and green control, in a timely manner according to the standard and processing requirements for fresh leaf picking.
