摘　　要：试验研究结果表明,在连作芹菜根际施用N、Y、D三种生物菌肥后,土壤根际3种酶的活性均高于未施用的酶活性。说明施用生物菌肥可以提高土壤对营养物质的代谢能力,从而促进芹菜的健康生长,解除连作障碍。Rhizosphere soil enzyme activity of continuous cultivating celery was obviously higher after being applied N, Y, and D bacterial manure, which showed that bacterial manure can improve metabolic capability of soil, maintain healthy growth of celery, and remove continuous cultivating problems.
