摘要： 进行了两茬蚯蚓粪田间肥力试验。结果表明，第二茬结束时，与试前相比，土壤有机质与全N全P含量，单施蚯蚓粪分别增加78.7%、47.9%、40.8%，施蚯蚓粪+化肥分别增加38.4%、21.9%、28.2%；三大微生物总量，单施蚯蚓粪、施蚯蚓粪+化肥分别增加108.2%、51.8%。施用蚯蚓粪能增加土壤速效养分含量，促进叶面积增长与干物质积累。一、二茬结束时，与不施肥相比，单施蚯蚓粪增产45.5%、77.5%，施蚯蚓粪+无机肥增产76.1%、103.9%，均达极显著水平。施用蚯蚓粪可改善甘蓝品质，降低甘蓝硝酸盐含量，提高维生素C含量。

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.
