It is investigated with plot experiments on fertilizer efficiency and increase yield effect of new photosynthetic bacterial?fertilizer on crops. The result shows that this kind of bacterial fertilizers can not only raise the output of eggplants, hot peppers and tomatoes, but also can reduce the occurrence of bad fruit. The outputs of eggplants increased 43.21% and 39.03% compared with control, the outputs of hot peppers increased 17.33% and 27.86%, the outputs of tomatoes increased 11.06% and 15.34%.Moreover,this kind of fertilizer could improve the soil quality. For example, it could increase soil organic matter and available N and available P. To tomatoes,the contents of soil organic matter increased 70.15% compared with control, the contents of soil available N increased 12.51% compared with control ,the contents of soil available P increased 17.00% compared with control. To hot peppers, the contents of soil available N increased 17.00% compared with control. To eggplants, the contents of soil organic matter increased 23.86% compared with control, the contents of soil available N increased 39.41% compared with control, the contents of soil available P increased 25.13% compared with control. At the same time, this kind of bacterial fertilizer could improve the absorbency of Fe. Mn. Cu. Zn.
