摘　　要：1993年在四川省农科院茶研所研究了茶树良种蜀永1号净光合速率与接侧多食附线螨Polyphagotarsnemus latus Banks雌成螨量水平、种群密度、叶片受害时间的关系.结果表明,茶树叶片净光合速率随接雌成螨量增加及受害时间推移均呈指数函数下降;随侧多食附线螨种群数量增加呈直线下降.因此,接雌成螨水平、叶片受害时间、害螨种群密度对茶树光合作用强度有显著的影响.另外,初始接雌成螨量大于8头/叶时,该螨种群消长受到抑制.A study on the relationship of net photosynthetic rate with inoculated amount of female adult mite,population density of mite and injured duration by mite was conducted in 1993. The results showed that the net photosynthetic rate declined in exponential function with both the increase of inoculated amount of female adult mite and injured duration,and declined in linear with the increase of population density of mite, so that the level of inoculated female adult mite, injred duration to tea leave and population density of mite all could be affected to the photosynthetic intensity of tea. Meanwhile,if the initially inoculated amount of female adult mite was more than 8 head per leaf,the increase or decrease of population density of mite would be inhibited.
