我国目前栽培的室内观叶植物,大部分从国外热带地区引进,栽培历史尚短,而且又多作室内无土栽培,病虫为害的机会相对较少。但调查结果表明,由于环境条件变化较大和栽培经验不足而引起的生理性病害则较为严重。这里着重介绍几种常见的病害及其防治方法。 Most of the indoor foliage plants cultivated in our country are introduced from tropical regions in foreign countries and have a short history of cultivation. Moreover, they are mostly used for indoor soilless culture and their pests and diseases are relatively less likely to be harmed. However, the survey results showed that the physiological diseases caused by the great changes in environmental conditions and lack of cultivation experience are more serious. Here are some common diseases and prevention methods.
