Former Yunnan Non-major Crop Variety Registration Committee Registration No. Dian Registration Tea Tree 2014009. [Variety Source]: Selected and bred from 'Yunnan Big Leaf Variety' by Tea Research Institute of Yunnan Academy of Agricultural Sciences. [Characteristics]: Small tree type, medium leaf type, late-blooming species. The tree posture is semi-open, the growth potential is medium, the branching part is high, and the branching density is medium. The leaf blade is upwardly inserted, the leaf blade is lanceolate, the length of the leaf blade is 11.0 centimeters, the width is 4.0 centimeters; the leaf color is green; the apex of the leaf blade is sharp. In the Menghai area, the full bloom of one bud and two leaves is generally in the middle of March, and the exploitation period of one bud and three leaves is generally in the second half of March. The germination density is high and the velvet is medium. The length of one bud and three leaves is 8.8 centimeters, and the weight of one hundred buds is 82.0 grams. Blooming period is in late September every year, corolla diameter 4.2 cm x 3.5 cm, petals 5-7, ovary velvet hairy, style 3 split. The biochemical sample of one bud and two leaves of spring tea contains 30.3% of tea polyphenols, 2.3% of amino acids, 4.2% of caffeine, and 50.7% of water leachate. Suitable for green tea and black tea. Making green tea, the aroma is still high and refreshing, sweet, mellow flavor, still sweet and fresh; making black tea, the aroma is sweet, fresh and refreshing, floral obvious, the taste is still thick and mellow, more sweet and fresh, slightly astringent. The first growth cycle mu yield of fresh leaves 340 kg, 10% yield reduction than the control 'cloud resistance 10'; the second growth cycle mu yield of fresh leaves 390 kg, 4% yield reduction than the control 'cloud resistance 10'. It is resistant to tea cloudy leaf blight, susceptible to tea cake disease, moderately resistant to small green leafhopper, moderately resistant to tea yellow thrips, susceptible to coffee small clawed mite. Strong cold resistance and drought resistance in Yunnan tea area. [Suitable for planting area and cultivation technology] Suitable for planting in the southwest ecological zone of Yunnan Xishuangbanna, Pu'er, Lincang, Baoshan, Dali, Dehong, Wenshan, Honghe, Lijiang, Nujiang area in the summer time when there is enough rainfall. Before planting, sufficient bottom fertilizer is applied, and young tea gardens are strictly pruned 3 times for stereotypes. 'Purple Juan' new tips purple buds, purple leaves, purple stems, made of green tea, sun green tea soup color are purple, special aroma, with its specificity. The new shoots are poor in tenderness, so it is necessary to strengthen the management of fertilizer cultivation, reapply base fertilizer and timely fertilizer to ensure the yield.
