The effect of application of photosynthetic bacteria of’Yannongguangpei No.1’to leaf age,plant height,numbers of plants,panicle stage and yield of was studied.The results indicated that there was no significant difference in leaf age and effective plant numbers among different disposal,whereas there were differences in plant height and panicle stage.This indicated that’Yannongguangpei No.1’could promote rice growth and made them ripen earlier.Yield of Treatments of 40 hm³/hm² pig feces and 100 L/hm² photosynthetic bacteria to subsoil was extremely higher than the control.The economic benefit increased 8381 yuan/hm² compared with the control.
