Abstract: Based on the bamboo vinegar, different cold-resistance agents of tea plants were formulated. Through simulating the natural air cooling, the biochemical and physiological indexes related to the ability of cold-resistance were determined after spraying six kinds of cold-resistance agents on three tea cultivars (Wuniuzao, Anji white tea and Longjing 43). The results showed a remarkable correlation between the change of the electric conductivity, soluble protein content, proline content and the cold-resistance in three tea cultivars. Furthermore, the physiological indexes of tea plants in lab and field trial were measured. Formulation B2 could obviously increase the cold-resistance of the tea plants, and maintain the yield of tea plant under cold stress. The results revealed that bamboo vinegar cold-resistant agents could enhance the cold-resistance of tea plant in some extent, reduce the freezing injury of tea plant, and prevent the tea from the reduction of yield caused by spring cold.
