摘　　要：非金属矿物质具有极强的吸附能力和离子交换作用,通过在香菇栽培基质中添加“矿质大菇料”的应用试验,结果表明,“矿质大菇料”对铅、镉、汞的吸附率分别为35.45%、9.38%、36.20%,对二氧化硫的吸附率为3.84%;同时可很好地提高菌棒的固型性,香菇菌棒平均杂菌污染率和烂筒发生率分别为6.95%和2.84%。由此证明,“矿质大菇料”具有吸附有害重金属离子和二氧化硫的作用,同时可减少菌棒杂菌的污染和烂筒的发生。According to the principle that nonmetallic mineral matters have absorption and ion exchange effect, sugar gypsum was added in cultivation substrates. The results showed that the absorption rate of sugar gypsum to lead, cadmium, mercury and sulfur dioxide was 35.45%, 9. 38%, 36. 20% and 3.84% respectively. The sugar gypsum could increase solidity of artificial log, and the rate of rotten and contamination bag was only 6. 95% and 2. 84% respectively. The results proved that the sugar gypsum could absorb harmful ion of heavy metals and sulfur dioxide at the same time, it could reduce the rate of rotten and contamination bag in Lentinula edodes cultivation.
