1.茶树的光合作用,无论在生长时期或生长休止时期,无论在晴天或阴雨天,无论是测定茶树的年龄和品种不同,其日变化的基本趋势都呈双高峯变化,正午前后伴随有“午睡現象”,“午睡現象”持续时间的长短因外界环境条件而异,但其强度低减弱程度均未超过早晚的最低水平。 2.茶树光合作用的季节进程为一单峯曲线的变化趋势,在杭州地区气候条件一下,七月份年平均气温最高时期,茶树的光合强度也达到年周期內最高水平。 3.茶树的光合强度在不同品种之间,茶树不同生育年龄之間以及不同外界环境条件下表現有很大差异,其平均光合强度居一般植物光合效率的中间水平。
1. The photosynthesis of tea tree showed a double-peaked change trend both in the growth period and the rest period, both in the sunny and in the rainy days, no matter the age and variety of the tea tree were measured, Nap phenomenon, “the phenomenon of” nap phenomenon "duration varies with the external environmental conditions, but its intensity is not reduced more than the minimum level of morning and evening. The tea plant photosynthesis season process is a unimodal curve trend, in the climatic conditions in Hangzhou area, the highest annual average temperature in July, tea tree photosynthetic intensity also reached the highest level in the year cycle. The photosynthetic intensity of tea plantations varied greatly among different varieties and between different growth stages of tea trees and under different external environmental conditions. The average photosynthetic rate of tea plants was in the middle of photosynthetic efficiency of common plants.
