摘要
大花蕙兰软腐病的发生发展与种植条件、气候条件有着重要的关系,高海拔地点比低海拔地点的发病轻,同一地点则4～10月发病较重,11月至次年3月发病较轻,发病率在0.2%～1.8%之间,病情指数最高可达到38.8。病原菌可以通过栽培基质、病株残体和昆虫介体进行传播,高温、高湿和大风则会促进该病的发生发展。
Our survey results showed that the occurrence and development of cymbidium sott rot had important relationship with planting and climatic conditions. The disease incidence rate at high - altitude locations was lighter than that at low - altitude locations. In the same place, it had serious disease during the period of April to October, but lighter incidence from November to March. The in- cidence rate was 0.2% ~ 1.8% with the highest disease index up to 38.8. Pathogens could be spread through culture medium, dis- eased plant debris, and insect vectors. High temperature, high humidity and great wind could promote the occurrence and development of this disease.
