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
