茶树对光的利用率很低,其原因是在夏秋季节,光饱和点只有自然光照的1/2—1/5;此外,树冠覆盖度小,漏光损失大。在强光、高温、低温条件下,给茶芽生长带来不利的影响,故我国大部分茶区夏秋雨季采摘的鲜叶,纤维素含量多,叶质硬化;花青素,多酚类含量高,致使茶味苦涩,这对提高绿茶品质极为不利。为改善茶园的生态条件,如何按照茶树系统发育的特点,因地因树制宜,利用生物间
Tea tree light utilization rate is very low, the reason is that in summer and autumn, light saturation point only natural light 1 / 2-1 / 5; In addition, canopy coverage, loss of large light leakage. In the light, high temperature, low temperature conditions, to bring adverse effects on the growth of tea buds, so most of our tea picking summer and autumn rainy season leaves, cellulose content, leaf hardening; anthocyanins, polyphenols content , Resulting in tea taste bitter, which is extremely detrimental to improving the quality of green tea. In order to improve the ecological conditions of tea plantations, how to follow the characteristics of tea tree system development,
