Abstract:: Taking broccoli as test materials，using the habit fertilizer application and different optimized fertilization treatments，screening for the optimized fertilization measure by potted planting experiment indoor were studied.The results showed that the optimized fertilization treatments improved the biological characters of broccoli，such as the plant height，stem diameter，dry and fresh weight；improved the content of soil available phosphorus and available potassium；increased the number of soil microorganisms；improved the nutrients absorption of nitrogen phosphorus and potassium，etc.Applying microbial fertilizer containing bacteria could significantly increase the content of soil bacteria.Compared with just applying inorganic fertilizers，applying inorganic fertilizer and also applying microbial fertilizer，reduced plant nitrogen content，improved potassium content.The effect of ‘fengmantun’ biological fertilizer was better than other microbial fertilizers.
