图3 氮水平对间作绿豆叶绿素荧光参数的影响 处理同图2。柱上不同小写字母代表在同一间作模式下各施氮水平在0.05水平差异显著。Fv/Fm: 最大光化学效率; ΦPSII: 实际光化学效率; NPQ: 非光化学淬灭系数。

Fig. 3 Effects of nitrogen level on the chlorophyll fluorescence parameters in intercropping mung bean Treatments are the same as those given in Fig. 2. Values followed by different lowercase letters above the bars mean significant differences at the 0.05 probability level in the same cropping pattern. Fv/Fm: the maximal photochemical efficiency of photosystem II; ΦPSII: the actual PSII efficiency (ΦPSII); NPQ: non-photochemical quenching coefficient.
