摘要：

比较了3种栽培方式（露地、大棚、温室）对越橘‘蓝丰’净光合速率（Pn）、气孔导度（Gs）、胞间CO2浓度（Ci）等光合参数的影响。结果表明：‘蓝丰’Pn日进程曲线呈“双峰”型，3种栽培方式下‘蓝丰’均出现光合午休现象。露地栽培的‘蓝丰’Gs高峰值出现在8:00点和18:00点，大棚和温室的Gs高峰值则出现在10:00点和16:00点，但三者的Gs最低值都出现在14:00点。3种栽培方式的‘蓝丰’Ci均是从6:00点开始下降，在10:00点到16:00点之间保持较低水平，16:00点之后开始迅速上升。进一步分析表明，露地栽培的‘蓝丰’在10:00-14:00点时的Pn下降主要受气孔限制因素的影响,而其他时间的Pn下降则是受非气孔限制因素影响。在设施栽培方式下，越橘‘蓝丰’Pn的下降主要是非气孔限制因素引起的。

Abstract:

The influences of three culturing modes (open field, green house, plastic house) on photosynthetic parameters of blueberry 'Bluecrop' were compared , including net photosynthetic rate (Pn), stomatal conductivity (Gs), intercellular CO2 concentration (Ci), etc. The results showed that 'Bluecrop' Pn day curve was two-peak type, photosynthetic midday drop of 'Bluecrop' was presented under three cultivation patterns. The minimum values of Gs under three culturing patterns were appeared at 14 p.m. and the maximum values of those were at different times, open field's were at 8 a.m. and 6 p.m., green house and plastic house's were all at 10 a.m. and 4 p.m. Ci of three culturing patterns was decreased from 6 a.m. till 10 a.m. and kept at a low level from 10 a.m. to 4 p.m., and then Ci started to increase. From those we concluded that the decline of Pn from 10 a.m. to 2 p.m. was contributed by stomatal-limitation factor, while there were non-stomatal-limitation factors about Pn decline at other time.
