[Variety Source] Ningbo Golden Rhyme Tea Industry Science and Technology Co. Ltd. and other units from the Yuyao local agricultural species buds and branches. [Characteristics and properties] Shrub type, early-blooming species, half-open posture, medium growth potential, low branching site, dense branching density; leaflets, leaf blade length 6.9 cm, width 2.7 cm, leaf blade narrow oval, apex shape obtuse, bearing state upward. Ningbo area spring tea bud one leaf period is generally in late March, bud two leaves in full bloom is generally in early April; light-sensitive yellowing tea, spring, summer, autumn and other seasons of the new shoots are yellow, germination density is high, the buds are more slender, less velvet, holding tenderness is good, a bud of three-leaf length of 4.8 cm, the weight of one hundred buds of 32.3 grams; full bloom beginning of the period of the beginning of every year in early November, easy to blossom, fewer fruits. The biochemical sample of spring tea bud and two leaves contains 17.3% of tea polyphenols, 5.8% of amino acids, 4.3% of caffeine, 46.9% of water leachate. Suitable for green tea. Baked green tea, yellow appearance, soup color bright yellow, aroma fresh and strong lasting, taste mellow and fresh, leaf bottom young goose yellow and bright. The first growth cycle mu yield of spring tea buds and leaves 19 kg of fresh leaves, an increase of 33% over the control 'Baiye 1'; the second growth cycle mu yield 27 kg, an increase of 39% over the control 'Baiye 1'. Medium resistance to tea anthracnose, medium resistance to tea leafhopper; medium cold resistance, weak drought resistance, weak resistance to sunburn at young age. [Suitable for cultivation area and cultivation technology points] Suitable for cultivation in Zhejiang, Jiangsu, Jiangxi, Guizhou, Anhui and Hubei. It is recommended to choose the annual cumulative temperature (≥10C˚) 4500C˚ area of light less, good supply of fertilizer and water, acidic soil of the northeastern slopes, valleys, in the fall or spring and other relatively abundant rainfall time planting; young tea plantations are recommended to take to reduce the sun, control the degree of yellowing of the cultivation measures, the amount of light in summer and autumn control in the full sunshine of 30% -50%, and at the same time, there should be a good guarantee of fertilizer and water.
