[Characteristics and properties] Shrubby, medium-leaved, medium-growing, strong growth potential, half-open posture, medium branching part, medium branching density. Leaf blade length 11.8 centimeters, width 4.5 centimeters, leaf blade attachment state slightly upward slanting, leaf blade shape long oval, leaf tip acuminate. In the Changsha area spring tea bud one leaf period in late March, the new buds and leaves yellowish-green, velvet hairs in the germination density. The bud and two leaves period is generally in early April. The bloom period is from mid-October to mid-November every year. The length of one bud and three leaves is 6.7 centimeters, and the weight of one bud and three leaves is 63.1 grams. The biochemical sample of one bud and two leaves in spring contains 20.3% of tea polyphenols, 5.2% of amino acids, 4.1% of caffeine, and 36.7% of water leachate. Suitable for green tea and black tea. Spring system green tea, appearance of tight, green, soup color tender green bright, aroma clear chestnut flavor, taste fresh and crisp; summer system black tea, appearance of tight, black and brown more moist, soup color red, aroma sweet incense high, taste is still sweet, the bottom of the leaf is red and bright. The first growth cycle mu yield of one bud and two leaves of 201 kg of fresh leaves, an increase of 233% over the control 'Fuding Dabaicha'; the second growth cycle mu yield of one bud and two leaves of 183 kg of fresh leaves, an increase of 16% over the control 'Fuding Dabaicha'. It is resistant to tea cloudy leaf blight, tea anthracnose, tea cake disease, false eye small green leafhopper, tea orange gall mite, coffee small clawed mite, cold resistance and drought resistance. [Suitable for planting area and cultivation technology points] Suitable for winter and spring in Hunan tea area, with early species. Single row double plant or double row double plant planting, young tea garden 3 times stereotypes pruning, batch leaf picking, picking and raising combination. Because of the strong growth, the amount of fertilizer can be increased by about 10% compared to the general varieties. The other according to the conventional tea garden cultivation management.
