Effects of Earthworm Biological Organic Fertilizer on Growth and Quality of Pakchoi

In order to promote the application and popularization of earthworm biological organic fertilizer,the pakchoi variety Huawang was used as the test material,four treatments of different gradient earthworm biological organic fertilizer and common organic fertilizer were set up to determine the growth index and yield of pakchoi,and the quality indexes of pakchoi such as VC,carbohydrate,protein,dietary fiber and nitrite content were detected.The results showed that when the application rate of vermicompost was more than 500 kg·667 m-2,the content of VC and protein in pakchoi was increased,the yield of pakchoi was significantly increased,and the accumulation of nitrite in pakchoi was effectively reduced.
