英文摘要	Lanzhou lily (Lilium davidii var. unicolor) is the only edible lily in China and it is a kind of narrow distribution endemic species and cultivated under monoculture and continuous system, which result in soil degradation and severe consecutive replant problems (CRPs). In this experiment, we investigated the soil physicchemical properties, microbial numbers, soil enzyme activities and yield in 20 sample fields with 0,3,6 and 9 years of replanting. The result showed that Continuous cropping significantly changed soil physiochemical properties and enzyme activities at the harvesting stage. By extending the period for replanting, the soil pH, salt content and organic matter increased significantly (p<0.05), while soil water content decreased significantly. The soil nutrient indexes such as Alkali-hydrolyzable nitrogen and available phosphorus also increased significantly while available potassium decreased. Moreover, the soil urease activities and phosphatase activities greatly improved, while hydrogen peroxidase and sucrase activities decreased with the continuous cropping. Generally, soil bacteria number decreased significantly, while soil fungi increased significantly, and the highest fungi/bacteria were recorded in the 9 year treatment. However, the highest actinomycetes numbers was recorded in 3-year and 9-year treatments. Continuous cropping also changed bulb yield and the yield components significantly, as well as deteriorated the bulb quality and storability. With prolonged replanting years, mother bulb weight and baby bulb numbers decreased, and the yield in 9-year treatment decreased significantly by 18.03% compared to 0-year treatment. These results demonstrated that soil transformation from a bacterial type to a fungal type, soil water-holding capacity decrease, soil salinization, especially excessive accumulation of available phosphorus played important role in soil degradation and yield decline under long-term continuous cropping. These results also suggest that some management practice such as soil disinfection, beneficial microorganism or bio-organic fertilizers usage, as well as decreasing phosphorus fertilizer input could help in maintain the soil quality and improve the yield and quality of Lanzhou lily in fields with more than 6 years of replanting.
