摘要
通过近5年在茶园喷施催芽素的应用研究,结果表明:在茶树越冬芽萌动时,喷施0.5％的催芽素,叶片光合速率增强,叶绿素含量增加;越冬芽早发多发、春茶提早开采;春茶增值22.76％、全年增值12.03％;绿茶感官品质及与品质密切相关的有效成分茶多酚、氨基酸、糖总量、维生素C、咖啡碱等含量均高于对照;对人体健康有益的硒、锌、铁等微量元素含量也高于对照。催芽素值得在茶叶生产上推广应用。
Applied study on foliar fertilizer for tea plants - Accelerating Bud Sprouting Matter (ABSM) has been lasting for five years. The results showed that spraying 0. 5% ABSM solution when the over - wintering buds were sprouting promoted photosynthesis rate, the chlorophyll content and sprouting of overwintering buds, evidently moved the date of picking up, increased the output value of spring tea by 22. 76% and the total output value over year by 12. 03% , and obtained better economic benefit year in year out. By spraying ABSM, the quality of green tea and the content of effective compositions closely related to the quality such as tea polophenols, amino acids, total sugar, Vc, caffeine and so on were higher than the control. The content of some minor elements (Se, Zn, Fe etc. ) benefited health were also higher. ABSM is worth popularization and appling in tea production.
