Abstract: A experiment was conducted in field to test efficiency of vermicompost ,and two crops were produced.The results showed that:when the second crop was finished,compared with that of soil before test,contents of soil organic matter,total N , P increased respectively by 78.7%,47.9% ,40.8% in the treatment of only applying vermicompost ,which also increased respectively by 38.4%,21.9% ,28.2% in the treatment of applying vermicompost with inorganic fertilizer; total number of the three sorts of microorganisms increased respectively by 108.2%,51.8% in two treatments of only applying vermicompost and applying vermicompost with inorganic fertilizer.Employing vermicompost could increase available nutrients ,promote the growth of leaf area,accelerate accumulation of dry matter.when the first and second crops were finished,compared to the treatment of no fertilizer, only applying vermicompost increased yield by 45.5% and 77.5%, applying vermicompost with inorganic fertilizer increased yield by 76.1% and 103.9%,the differene was great significant. Employing vermicompost could improve the quality of cabbage,decrease nitrate content,and increse the content of Vc.
