[Variety Source] Selected by the Tea Research Institute of the Sichuan Academy of Agricultural Sciences and others as a single selection from the 'Sichuan Medium and Small-Leafed Species'. [Characteristics and properties]: Shrub type, early species, half-open posture, medium leaf type, leaf length 9.3 cm, width 3.7 cm, narrow elliptic, leaf bearing attitude upward; adult leaf yellow-green, new green yellow, exploitation period is generally in late February, a bud two leaves bloom period is generally in the first half of March, the germination density of the medium, less velvet hairs, a bud of three leaves is 8.1 cm long, the weight of one hundred buds of 41.7 g. The first bud of three leaves in spring biochemical samples of biochemical samples of biochemical samples of biochemical samples of biochemical samples of the spring bud of two leaves of the spring of one bud of 41.7 g. The biochemical sample of spring bud and two leaves contains 20.3% of tea polyphenols, 3.9% of amino acids, 4.3% of caffeine, and 51.0% of water leachate. Suitable for green tea. Green tea, curly yellow-green appearance, oily and moist hair, aroma of flowers, soup color is tender yellow and bright, taste fresh and mellow, leaf bottom is tender yellow and bright, buds and leaves complete into a flower. The first growth cycle of the annual mu yield of one bud and two leaves of 302 kg of fresh leaves, than the control 4 in the yellow 1 '15% increase in yield; the second growth cycle of the annual mu yield of one bud and two leaves of 311 kg of fresh leaves, than the control 'in the yellow 1 '12% increase in yield. It is resistant to tea anthracnose, tea leafhopper, drought resistance and cold resistance. [Suitable for planting area and cultivation technology points] Suitable for planting in the southwest ecological zone of Sichuan tea area in spring and fall. Because of the yellowing of the special varieties of light is sensitive, in the sun's light in the area of cultivation can build awnings, can block part of the sun, but also reduce soil moisture evaporation, to be the tea tree into the garden or light weakened, and then remove the awning, to avoid the strong light burns the young new shoots. After transplanting shall be 3 times stereotypes pruning, planting the third year can be the first production.
