摘　　要：采用经典实验方法和分子鉴定技术进行了木霉菌株T11-W的鉴定及其对南方根结线虫分散卵的寄生性研究。结果表明,T11-W为哈茨木霉(Trichoderma harzianum),对南方根结线虫分散卵具有寄生作用,校正寄生率为73.46%,相对孵化抑制率为94.19%。本文丰富了木霉菌防治南方根结线虫的理论研究,对哈茨木霉作为新型、高效的微生物杀线剂的生产具有一定的指导意义。We employed classical experiment methods and molecular identification technology to identify T11-W and its parasitism to Meloidogyne incognita eggs to investigate the parasitism of strain Ttl-W to M. incognita eggs. Results show that strain T11-W is Trichoderma harzianum and it has parasitism to M. incognita nematode eggs. It has correction parasitism rate of 73.46% and relative hatch inhibition rate of 94.19%. Our research improves the theory of the prevention of Trichoderma harzianum to M. incognita. It has the prospect of acting as a new and highly efficient microbial nematicide.
