摘要
针对药用植物长期栽培或连作中土壤环境恶化的特点,综述了土壤养分缺乏、土壤酸碱度变化、有害盐类含量增加、土壤有害微生物增加、土壤化感物质增加、土壤理化性质改变等种种土壤环境恶化的表现,指出药用植物土壤环境恶化的综合防治手段,包括:选育抗逆境中药品种、实施轮作等科学的栽培管理、科学补充土壤营养元素、选用合适的物理处理技术、开展营养液培养、接种VAM真菌栽培等。
This paper summarized the aspects of the soft deterioration due to continuous growth of medicinal plants, such as nutrition insufficient, pH variation, harmful salt accumulating, harmful microbe and alldopathic substance increasing, soil physics and chemistry properties variation. And the ways to prevent and rehabilitate the deteriorated soft was indicated, which included anti-adversity species selecting, scientific management such as whorl cropping, nutrient elements supplement, usage of physical methods, nutrient liquid cultivating and VAM inoculating etc.
