摘要: 以竹醋液为基液,配制了不同茶树抗寒剂,并进行了茶树生理抗寒指标的研究。在对3个茶树品种(乌牛早、安吉白茶和龙井43)喷施6种不同配方的抗寒剂后,经模拟田间自然降温,测定处理前后茶树中与抗寒能力相关的理化物质。结果显示,3个茶树品种间各处理的电导率、可溶性蛋白和脯氨酸含量的变化规律与茶树冻害情况具有显著相关性。通过测定室内茶树生理生化指标和田间试验结果分析表明,配方B2能显著提高茶树的抗寒性,并可稳定冷害胁迫下的茶叶产量。结果表明,竹醋基液抗寒剂可在一定程度上提高茶树的抗寒能力,有效降低茶树的冻害,从而保证茶叶生产免受冻害损失。

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.

Key words: bamboo vinegar, tea plant, cold-resistance, physiological indexes
