为探讨加气滴灌对蓝莓叶绿素荧光特性的影响，以日光温室内种植的 3 a 生蓝莓幼苗为试验材料，研究分析了不同滴灌模式下蓝莓叶片 PSⅡ反应中心叶绿素荧光参数的响应机制。结果表明，采用加气滴灌可以提高蓝莓叶片PSⅡ反应中心最大荧光产量(Fm)，且不同加气频率对叶片最大荧光 Fm值具有显著影响（P<0.05）；与常规滴灌相比较，在试验处理初期，加气滴灌对应的植株叶片 PSⅡ反应中心潜在光化学活性(Fv/F0)增幅较小，但随着时间的推移，其差异越来越明显；加气滴灌有利于提高蓝莓叶片 PSⅡ光能捕获效率(Fv′/Fm′)，同时提高了叶片实际光化学效率(Yield)和光化学猝灭系数(q P)，且加气频率不同，叶片 PSⅡ电子传递活性表现出较大的差异。加气处理对蓝莓叶片非光化学猝灭系数(NPQ)的影响较小，在整个试验期间均无显著差异。此外，根系活力分析结果表明，通过加气处理可以改善蓝莓根系生长环境，促进根系对养分的吸收。
In order to investigate the effect of aerated drip irrigation on the chlorophyll fluorescence characteristics of blueberry, the response mechanism of the PSⅡ reaction center chlorophyll fluorescence parameters under different drip irrigation patterns was studied using 3 a blueberry seedlings grown in solar greenhouse as test materials. The results showed that aeration drip irrigation could increase the maximum fluorescence yield (Fm) of PSⅡ reaction center of blueberry leaves, and different filling frequency had significant effects on the maximum fluorescence Fm of leaves (P <0.05). Compared with conventional drip irrigation, In the initial stage, the potential photochemical activity (Fv / F0) of PSⅡ reaction center of plant leaves corresponding to aerated drip irrigation increased slightly, but the difference became more and more obvious with the passage of time; aeration drip irrigation was beneficial to improve the PSⅡ light energy capture of blueberry leaves (Fv ’/ Fm’). Meanwhile, the actual photochemical efficiency (Yield) and photochemical quenching coefficient (q P) of leaves were increased. At different aeration frequencies, the electron transport activities of PSⅡ in leaves showed great differences. The effect of aeration treatment on the non-photochemical quenching coefficient (NPQ) of blueberry leaves was insignificant, and there was no significant difference during the whole experiment. In addition, the results of root vitality analysis showed that the rooting environment of blueberry can be improved and the nutrient absorption by roots can be improved by aeration treatment.
