tractThe spring shoot growth dynamic was examined and studied with five cultivars in the west-Sichuan tea area. The result is that under the condition of and elevation of 1060 metres in west-Sichuan, every variety has significant difference in growth time and intensity of spring shoot. Fuding Dabai cha still has the early buddng, fast spreading and early plucking varietal characteristics. Famous tea begins to pluck 6 to 10 days earlier than the others. Statoblasts of these varieties need 19 to 26 days and accumulated temperature 150 to 220 degrees cntigrade, to form a bud with a leaf, while 37 to 53 days and 330 to 510 degrees centigrade to from a bud with 3 leaves. So famous tea in high elevations begins to pluck later commonly. Early budding and high efficient planting techniques should be taken to pluck famous tea materials more and earlier.
