Abstract:

To understand the continuous cropping obstacles of large-scale vegetable bases in Hangzhou, 20 representative vegetable bases were selected and the physical and chemical properties of topsoil from the bases were analyzed based on the investigation. The results showed that the average planting years of the base were 13.75 a, the phenomenon of continuous cropping was common, the obstacles of continuous cropping were prominent, the average crop yield reduced 15.0%, and the application amount of fertilizer was too large. Soil degradation was serious, and 55.0% of the samples was in pH≤5.5. Samples with salt content >0.2% accounted for 35.0%; the enrichment of available phosphorus and available potassium in soil was obvious, with average values of 93.8 mg/kg and 516 mg/kg, respectively. In view of the degradation problem, the corresponding prevention and control measures were put forward.

Key words: large-scale facility vegetable base, continuous cropping obstacle, soil acidification, secondary salinization, nutrient enrichment
