摘　　要：为研究外源硒不同添加方式对双孢蘑菇产量、营养品质和重金属富集的影响,分别在栽培料、覆土、栽培料+覆土中添加亚硒酸钠,测定了双孢蘑菇产量、营养品质、硒含量及重金属富集情况。结果表明,在生长初期,栽培料+覆土添加硒、覆土添加硒2个处理的双孢蘑菇硒含量高于栽培料添加硒处理,表现出显著的富集效果。栽培料添加硒处理和覆土添加硒处理下双孢蘑菇硒含量在整个生长周期稳定性较好。栽培料中添加硒能显著提高双孢蘑菇的产量,尤其在第二潮能获得更高产量。外源硒添加一定程度上能提升双孢蘑菇中蛋白质的含量,改善其子实体营养品质。综上,栽培料中添加硒可提高生产中双孢蘑菇子实体产量,改善其营养品质。This study investigated effects of different methods of exogenous selenium addition into the the cultivation material,soil cover,cultivation material and soil cover on the yield,nutritional quality,and heavy metal enrichment in Agaricus bisporus,using sodium selenite.The results indicated that in the early stages of growth,selenium content in A.bisporus from the cultivation material and soil cover and soil cover treatments was higher than in the cultivation material treatment alone,showing a significant enrichment effect.Selenium content in A.bisporus under the cultivation material,soil cover selenium addition treatments maintained good stability throughout the growth cycle.Adding selenium to the cultivation substrate significantly increased the yield of A.bisporus,especially during the second tide.Exogenous selenium addition also enhanced the protein content in A.bisporus,improving their fruiting body nutritional quality.In conclusion,adding selenium to the cultivation substrate can increase the yield of the fruiting bodies and improve the nutritional quality of A.bisporus in production.
