Effect of vermicompost and bacillus megaterium on nutrientcontent，yield，quality and soil physical and chemicalproperties of pakchoi were studied to provide a theoretical basis for improving leaf vegetable quality and scientificfertilization.Pakchoi was used as test materials，effects of different treatments on nutrient content，yield and quality(vitamin C，freeamino acid andnitrate)and soil physical and chemical properties in pakchoi were studied by cultivation experiment ingreenhouses，and the treatments were respectively that vermicompost replaced the amount ofurea(0，20%，40%，60%，80%，100%)and bacillus megateriumapplication(0，6 kg/hm²).The results showed that compared with the chemicalfertilizer，the application of vermicompost，vermicompost + bacillus megaterium significantly improved the yield and qualityofpakchoi，andyield，free aminoacid，vitamin C content was the highest and the content of nitrate was the lowest when40% urea was replaced byvermicompost.On thisbasis，the addition of bacillus megaterium could further increase the yieldand improve thequality.The application ofvermicompost，vermicompost + bacillus megaterium significantly increasedpH，availablenitrogen，available phosphorus and available potassium in soil，and the improvement was more prominent when vermicompost replaced 40% urea + 6 kg/hm²bacillusmegaterium.
