Effect of the Biological Organic Fertilizer on the Growth and Quality of Coles

In this paper,biological organic fertilizer was used in Cole production using biological organic fertilizer with inorganic fertilizer and using inorganic fertilizer.The results indicated: compared with using inorganic fertilizer,leaf content of nitrate and nitrite declined 36.17% and 21.77% when using biological organic fertilizer;in the soil where grew Coles,the organic matter increased by 11.12%.In Cole production,using biological organic fertilizer were propitious to improve crop quality,soil fertilizer and organic matter content in the soil.There was no significant decrease in yield when using biological organic fertilizer with inorganic fertilizer.
