不同管理模式对茶树生物学指标和化学成分的影响
目的 研究不同管理模式对茶树生物学指标和化学成分的影响。方法 选取9个不同的茶树品种, 均为10龄茶树, 分别进行现代茶园修剪管理和自然生长处理, 对比分析不同处理下各品种的开采日期、测量树高和百芽重、检测茶多酚、氨基酸等化学成分。结果 不同品种现代茶园的开采日期比自然生长茶园提前6~16 d, 氨基酸含量平均比自然生长茶园高0.79%, 自然生长茶园的树高为现代茶园的4~7倍, 百芽重、茶多酚、水浸出物、咖啡碱等指标不同品种表现出不同的规律。结论 不同管理模式对茶树生物学指标和化学成分有一定影响, 两种管理模式下不同品种存在一定差异, 可根据需求对不同品种采用不同的管理模式, 同时为野生茶树的研究提供支持。
Objective To investigate the effects of different management modes on biological indexes and chemical components of tea plant. Methods Nine tea varieties of ten years dealt with modern tea garden pruning management and natural growth, then all varieties with different treatments were analyzed of picking date, tree height, one hundred bud weigh, and other chemical components such as tea polyphenols, amino acid and so on. Results Different varieties of modern tea garden had 6~16 d of picking date earlier than that of natural growth garden, amino acid content were 0.79% higher than that of natural growth garden, tea plant in natural growth garden had 4~7 times higher than that of modern tea garden, and different varieties showed different laws on one hundred bud weigh, tea polyphenols, water extract and caffeine content. Conclusion Different management modes can affect tea plant on physiological indexes and chemical components, different varieties have some differences under 2 management modes, so we can choose different management modes on demands, and it provides support for wild tea plant research.
