摘要: 旱地番茄因含糖量高、酸度低、沙瓤细腻、营养价值高等特点而受到人们广泛热爱,但连年种植,易引起连作障碍,给旱地番茄栽培带来严重危害。针对旱地番茄存在的连作障碍问题,文章从土壤功能的退化、真菌土传病害的发生和化感物质的影响3个方面阐述了连作障碍的原因,分析了土壤理化性质、酶活性和微生物种群结构变化对连作障碍机制的影响,探讨了土传病害的致病机理和化感物质的主要成分及来源,提出克服旱地番茄种植的连作障碍措施,并对旱地番茄连作障碍的研究进展进行了展望。

Abstract: Dryland tomato is widely loved because of their high sugar content,low acidity,fine sand,and having high nutritional value and so on,but the traditional method of crop planting adopts continuous cropping,and it brings great loss to dryland tomato. According to the continuous cropping obstacle on dryland tomato,the causes of continuous cropping obstacles were explained from three aspects in this paper,including of the deterioration of soil function,the occurrence of fungal soil-borne diseases,and the influence of allelochemicals. The effects of soil physical and chemical properties,the enzyme activities,and the microbial population structure changes on the mechanism of continuous cropping were analyzed. We also discussed the pathogenic mechanism of soil-borne diseases and the main components and sources of allelochemicals,and proposed measures of overcoming dryland tomato obstacle. The research progress on continuous dryland tomato production obstacle is in prospect.

Key words: Dryland tomato, Continuous cropping obstacle, Soil properties, Soil-borne diseases, Allelochemicals
