摘要
为探讨茶树间作巨菌草对秋冬季节茶叶生化成分含量的影响,本研究对茶与巨菌草复合栽培模式下茶叶生化成分含量进行对比测定。结果表明:间作巨菌草后,茶叶咖啡碱含量、茶多酚含量及游离氨基酸总量均低于对照,且差异达到显著水平,间作巨菌草在一定程度上降低了茶叶的苦涩味。
In order to explore the effects of tea-(Pennisetum giganteum)intercropping on the contents of biochemical components of tea in autumn and winter,it was detected that the content of biochemical components of tea under the tea-(Pennisetum giganteum)intercropping and single tea plantation.The results showed that the contents of caffeine,tea polyphenols,and total free amino acids in tea-(Pennisetum giganteum)intercropping were lower than those in control,and the differences reached a significant level.Intercropping(Pennisetum giganteum)neutralized the bitter and astringent taste of tea to a certain extent.
