摘　　要： 研究了不同天气条件下猕猴桃冠幕的温度微气候、叶片光合速率及其日变化进程的差异.高温干旱天冠幕的叶果际温度对树体生长结实与系列生理代讲活动有严重的阻碍作用,高温干旱天与阴天叶片的光合速率大大降低,高温干旱条件改变了叶片光合速率的日变化进程. The canopy microclimate, leaf photosynthetic rate and diurnal variation pattern in kiwifruit under different weather conditions were studied comparatively in the paper. The results showed: the leaf and fruit temperature in canopy under high temperature and dry weather condition hindered vine growth, fruit development and physiological metabolism. Leaf photosynthetic rate under overcast, high temperature and dry weather conditions declined greatly. The diurnal variation pattern of photosynthetic rate differed under different weather conditions.
