With a view to knowing more about how NaHSO〓 increased Pn in higher plants, we studied the effects of NaHSO〓 on the cyclic electron flow around PSI in wheat (Jing 411) and rice (Shan-you 63). It was observed that the transient increase in chlorophyll fluorescence after the termination of actinic light was increased and the half-time of re-reduction of P700〓 was shortened in both rice and wheat leaves, indicating that cyclic electron flow around PSI was accelerated by NaHSO〓 treatment.

为探究NaHSO〓促进高等植物光合作用的机理，我们研究了NaHSO〓对小麦（京411）和水稻（汕优63）围绕PSI的循环电子传递影响，实验发现低浓度NaHSO〓可促进小麦和水稻叶片的叶绿素荧光在作用光关闭后的短时上升以及缩短叶片在远红光后P700〓再还原的半时间，表明NaHSO〓可以促进小麦和水稻的围绕PSI的循环电子传递。

In accord with the promotion in the photosynthetic oxygen evolution and ATP content, the transient increase in chlorophyll fluorescence after the termination of actinic light was increased; and meanwhile, the half-time of re-reduction of P700〓 in the presence of DCMU after a pulse light under background far-red light was shortened by approximately 30%, indicating that cyclic electron flow around PS1 was accelerated by the treatment.

与此同时，我们还发现经NaHSO〓处理后，蓝藻细胞的作用光关闭后叶绿素荧光瞬时上升的幅度增加，同时在远红光背景下和DCMU存在时，饱和闪光后蓝藻细胞P700〓再还原的半时间缩短约30％，表明低浓度NaHSO〓溶液处理能够促进蓝藻细胞围绕PSI的循环电子传递。

The contents of chlorophyll and the catalase activity of celery were increased 19.06%, 6.52% in the once top-dressing treatment with 300ml biogas slurry (A1I) than that applied chemical fertilizer (A1I).

其中一次施用300ml沼液的追肥处理(A1I)比化肥处理（B1I）对芹菜的叶绿素含量、过氧化氢酶活性分别提高了19.06%、6.52%；一次施用900ml沼液的追肥处理(A2I)比化肥处理（B2I）对芹菜的VC含量、还原糖含量分别提高了9.07%、51.31%，硝酸盐含量下降了31.65%；且施用沼液时一次施用与分次施用对芹菜的品质、产量无显著影响，化肥的分次施用与化肥的一次施用相比，芹菜的硝酸盐含量显著降低。
