摘　　要：通过盆栽试验,研究了菇床废料对缓解设施栽培土壤次生盐渍化及小白菜盐胁迫的影响.结果表明:盐渍化土壤添加菇床废料(0～30g·kg-1)栽培60d后,土壤pH趋于中性,有机质和有效磷含量显著提高,水溶性盐总量的增加幅度小于不加菇床废料的对照土壤;当菇床废料添加量为10g·kg-1时,土壤盐分增加幅度最小,说明适量添加菇床废料可以减少设施栽培土壤的盐分积累.加入菇床废料后,小白菜的种子发芽率、株高、鲜质量、叶绿素SPAD值和维生素C含量均有所提高,脯氨酸含量显著下降,说明菇床废料能改善小白菜生长环境,有效缓解盐胁迫对小白菜的危害.A pot experiment was conducted to study the effect of spent mushroom compost（SMC） in alleviating greenhouse soil secondary salinization and cabbage salt stress.With the amendment of SMC,the salinized soil after 60 day cabbage cultivation had a pH value close to 7.0,its organic matter and available phosphorous contents increased significantly,and the increment of total water-soluble salt content reduced,compared with the control.When the amendment amount of SMC was 10 g·kg-1,the increment of soil water soluble salt content was the least,suggesting that appropriate amendment with SMC could reduce the salt accumulation in greenhouse soil.Amendment with SMC increased the cabbage seed germination rate,plant height,plant fresh mass,chlorophyll SPAD value,and vitamin C content,and decreased the proline content significantly.All the results indicated that SMC could improve the growth environment of greenhouse cabbage,and effectively alleviate the detrimental effect of salt stress.
