以红提为试验材料，利用LI-6400便携式光合仪在露地和简易棚2种栽培条件下，测定葡萄叶片的净光合速率、胞间CO2浓度等参数。结果表明：避雨栽培降低了葡萄叶片的净光合速率、胞间CO2浓度和叶室内部光强，降幅分别为14.06%、7.46%和41.72%，与露地栽培相比，差异均达到了极显著水平。避雨栽培提高了葡萄叶片的蒸腾速率，升幅为0.50%；降低了葡萄叶面温度，降幅为0.71%，与露地栽培相比差异不显著。

The grape variety of Hongti was used to study the influence of rainproof cultivation on photosynthetic characteristics of grape leaves by using the LI-6400 portable photosynthesis system in this paper.The results showed that there were highly significant differences on the net photosynthetic rate,the intercellular CO2 concentration of grape leaves and the in-chamber quantum sensor under rainproof cultivation and at outdoor. The leaves infected percentage of net photosynthetic rate was reduced by 14.06%,the intercellular CO2 concentration was decreased by 7.46%,and the in-chamber quantum sensor was also reduced by 41.72%under rainproof cultivation.The transpiration rate of grape leaves and leaf temperature had no significant differences under two growing conditions ,which were only by 0.50%and 0.71%.
