摘　　要：分别以磷酸二氢钾、生命素、翠筠B-2成长肥3种叶面肥的4种不同浓度喷施虎雪兰,分析3种叶面肥在不同浓度处理下,对虎雪兰光合生理特性的影响。结果表明:虎雪兰在翠筠B-2肥料500倍浓度喷施下,其净光合速率、气孔导度、蒸腾速率相对较大,胞间CO2浓度较小,光合效率高,有利于虎雪兰植株更快地生长。By taking Cymbidium huxueense as the research object, randomized block experiment was used, thechange of the photosynthetic physiological characteristics of Cymbidium huxueense by fertilized with 3 different foliarfertilizers （Potassium Dihydrogen Phosphate, Biogen and Cuijun B -2 ） were studied. The results showed thatwhen the concentration of Cuijun B - 2 was 500 times, photosynthetic physiology, net photosynthetic rate, stomatalconductance and transpiration rate of Cymbidium huxueense were higher, while the intercellular CO2 concentrationwas lower, which was beneficial to exuberant growth.
