中文摘要： 人参产业是吉林省长白山区的重要支柱产业，但是人参生产每年因各种病害造成的经济损失巨大，老参地栽参和农田栽参时人参病害尤其严重。对人参病害采用生物防治是保证人参药材的安全性和实现人参可持续发展的必然选择，而且吉林省有十分丰富的人参内生菌资源，可利用植物内生菌及其次生代谢产物能促进植物生长，增强宿主植物的竞争力和抗逆性，抑制病原菌等的特性，来防治人参病害。本研究通过对吉林省六个人参主产地人参内生菌的多样性调查，初步掌握吉林省人参内生菌的种类、数量和种群结构，从中分离、筛选出人参主要病害致病菌的拮抗内生菌株，利用盆栽实验进行检验复筛，并对筛选出的内生菌进行大田试验，研究探讨其生防、促生效果及机理，为内生菌在人参病害防治中的应用提供理论和试验依据，也可为内生菌在老参地改良中的应用提供参考。项目预期将初步了解吉林省人参内生菌的多样性资源，并为人参病害的生物防治找到新资源。

英文摘要： Ginseng industry is the important pillar industry in Changbai Mountain district of Jilin Province. But because of various disease in producing ginseng, there is a hugh economic loss, especially for those in planted ginseng field and farmlands. Biological control on ginseng disease is an inevitable choice for ensuring the safety of ginseng medicine materials and realizing the sustainable development of ginseng. Jilin province has plenty of Ginseng endophyte resources, so that it can use characteristics of plant endophyte and its secondary metabolites which promote the growth of the plant, enhance the competitiveness and stress resistance of the host plants, and inhibit pathogenic bacteria, and etc to prevent the ginseng disease.Through diversity survey of the ginseng endophytes from six ginseng field in Jilin Province, this research initially grasps the types of ginseng endophytes, amount and population structure in Jilin province, then separates and selects antagonism endophytes that will cause ginseng disease, selects and tests repectively by doing pot experiments, tests the selected endophytes through field testing, studies and discusses the preventing and growth promoting effect and its machanism, and provides theory and experiment basis fot the application of endophytes in the prevention of the ginseng disea
