Taking Lu cucumber No.3 as material, the effects of photosynthetic bacterial fertilizer on enzyme activity and microorganism biomass of substrate, plug-seedling growth and root morphology of cucumber were studied.The result showed that the quantity of micro-biomass, bacteria and actinomyce in substrate were significantly increased, but the quantity of fungi was opposite, after the photosynthetic bacterial fertilizer treatments.Activities of substrate enzymes(Invertase, Urease, Neutral phosphatase and Catalase) were significantly enhanced.Root activity and ability of root morphogenesis of cucumber seedlings were effectively improved by the photosynthetic bacterial fertilizer, also with root absorption area and root tips increased.So, all the photosynthetic bacterial fertilizer treatments could significantly enhance the quality of cucumber seedlings, and the best dilution multiple was 200 times (Treatment 2)for cucumber plug-seedlings.Correlation analysis showed that sound seedlings index(SSI) of cucumber plug-seedlings had a significant positive correlation with substrate micro-biomass(r=0.95*), and had an extremely significant positive correlation with substrate bacteria number(r=0.98**), but significant negative correlation of SSI and substrate fungi number(r=-0.89*).In summery, the increasing of bacteria and micro-biomass quantity of substrate should be valued at the premise of the substrate physicochemical property in optimum range, which could promote the quality of cucumber plug-seedlings.Application photosynthetic bacterial fertilizer could improve microbial structure and microbial diversity of cucumber plug-seedling substrate, promote the quantity of bacteria, actinomyce, micro-biomass and substrates enzyme activity, and reduce the quantity of fungi.It also could enhance the provision nutrition ability of substrate, promote root coordinational growth, increase root absorption area, accelerate the seedlings growth, and finally improve the quality of cucumber plug-seedlings.
