培养料及覆土中总Cd（2＋）浓度对蘑菇子实体的影响
Effects of the Total Cd_（2＋） Concentration in Culture Material and Covering Soil on Mushroom Fruitbodies
摘要
Abstract
The objective of this study was to investigate the source and the capacity to adsorbent of the Cd2＋ in fruitbodies of Agaricus bisporus, the enrichment law of Cd2＋ from first flush and second flush of fruitbodies of Agaricus bisporus 2796 was analysised through adding Cd2＋ion to culture material and covering soil to confirm the critical content value of Cd2＋ion concentration in the cultivation process. The results showed that the Agaricus bisporus didn’t have enrichment effect on Cd, and the average Cd absorption coefficient from culture material for the first flush of fruitbodies was 0.329. It was 21.1 times to 0.0156 from covering soil. And the similar data was 0.122 for second flush of fruitbodies to Cd from culture material, that was 9.5 times higher than that 0.0128 from covering soil. It also showed that it can inhibit the knot growth of the Agaricus bisporu’;s fruitbodies and make total crop failure when the concentration of Cd2 ＋ ion was higher than 40 mg/kg. It suggested that the detection of Cd＋ion of the culture material was very important in the cultivation process of Agaricus bisporus. When the Cd content of fruitbodies conforms to the no social effects of pollution standardization and the green foods standardizaton for mushroom in China, the value of the critical content of Cd from culture material and covering soil was 6.70 mg/kg, 1.45 mg/kg, 32.66mg/kg and 5.39mg/kg by regression model, respectivily.关键词
