Abstract:
Taking Brassica chinensis as materials,the effect of chicken manure and cow manure under combined pollution of cadmium and nitrate on the yield and quality of Brassica chinensis-soil system and soil enzyme activity were studied by setting 7 different fertilization treatments.The results showed that the different treatments of chicken manure and cow dung could significantly increased the fresh weight of Brassica chinensis,soil protease activity and acid phosphatase activity;compared with the control,the application of chicken manure (50 g/5kg soil) and cow dung (50 g/5kg soil,100 g/5kg soil) significantly improved the content of Brassica chinensis vitamin C,increased by 4.98%,9.78% and 15.12% respectively.The application of chicken manure (20 g/5kg soil,50 g/5kg soil,100 g/5kg soil) and cow dung (100 g/5kg soil) significantly decreased the contents of Brassica chinensis Cd,decreased by 10.55%,7.67%,35.76%,18.79%.The application of chicken manure (20 g/5kg soil,100 g/5kg soil) and cow dung (20 g/5kg soil) significantly decreased the contents of Brassica chinensis nitrate,decreased by 11.07%,18.26%,29.09%.The application of chicken manure (50g/5kg soil) significantly increased urease activity and the application of cow manure (20 g/5kg soil,50 g/5kg soil,100 g/5kg soil) significantly increased soil invertase activity.
