为了对川贝母（Fritillaria cirrhosa D．Don）的规范化栽培提供试验数据支撑，以青藏高原高山草甸区川贝母树儿子和灯笼花期植株为材料，设置荫蔽度、棚高和遮阴网颜色3个因素，每个因素设置3个水平，以不遮阴为对照，研究不同遮阴条件对川贝母光合特性的影响。结果表明：遮阴导致川贝母树儿子期植株净光合速率降低，光量子效率和蒸腾速率提高，对其气孔导度、胞间二氧化碳浓度的影响不显著；遮阴显著降低了川贝母灯笼花期植株净光合速率、胞间二氧化碳浓度、蒸腾速率，显著增强了其植株的气孔导度和光量子效率。结论：遮阴不利于青藏高原地区栽培3年生及以上的川贝母植株净光合速率的提高及其物质的积累，不采用遮阴措施栽培川贝母更经济和环保。

F.cirrhosa plants without flowering and with flowering and fruit-bearing from alpine meadow of Tibet Plateau were cultivated under different shading condition to study the effect on photosynthetic characteristics of F.cirrhosa and to provide a reference for standardization cultivation of F. cirrhosa.The results showed that shading can decrease net photosynthetic rate, increase quantum efficiency and transpiration rate,and has no significant effects on stomatal conductance and intercellular CO2 concentration of F.cirrhosa plants without flowering,but shading decreases net photosynthetic rate, intercellular CO2 concentration and transpiration rate and increases stomatal conductance and quantum efficiency of F.cirrhosa plants with flowering and fruit-bearing significantly.In conclusion,shading is not conductive to increase net photosynthetic rate and dry matter accumulation of F.cirrhosa plants with 3-year and over 3-year old in Tibet Plateau.
