摘要
根结线虫Meloidogyne spp.和孢囊线虫Heterodera spp.是分布最广、危害最严重的两类植物病原线虫。它们寄生于植物根部,通过巨型细胞或合胞体获取营养,影响植物生长发育,对农作物造成严重的经济损失。木霉菌Trichoderma spp.是农业生产中重要的生防资源。近年来,随着环境保护意识的提升,木霉菌作为植物寄生线虫的生防资源越来越受到重视。本文主要从木霉菌对根结线虫和孢囊线虫的生防机制、作用方式、影响因素及存在的问题等方面进行综述,分析木霉菌在生物防治中存在的问题,并对其应用前景进行展望。
Root-knot nematode(Meloidogyne spp.)and cyst nematode(Heterodera spp.)are two kinds of plant-parasitic nematodes that are the most agriculturally damaging group of plant-parasitic nematodes worldwide.They infect roots the of the host plant,obtaining nutrition through giant cells or syncytia,affecting plant growth and development,and causing severe economic losses to crops.Trichoderma spp.is an important biocontrol resource in agricultural production.With the improvement of environmental protection awareness,Trichoderma spp.has recently attracted more and more attention as a biocontrol resource of plant-parasitic nematodes.Here we discussed the biocontrol mechanism,action mode,influencing factors,existing problems,and production application of Trichoderma against root-knot nematode and cyst nematode.Finally,we analyzed the issues of Trichoderma in biological control and provided insight into their application.
