中文摘要：

开展利用微生物发酵床养猪垫料废料（不同添加比例）栽培毛木耳（Auricularia polytricha ）研究,分析其对毛木耳的产量、品质及重金属含量的影响。结果表明,垫料添加到30%时（垫料30%,木屑49%,棉籽壳11%,麸皮7%,1%石膏,1%石灰,1%轻质碳酸钙,含水量为63%）,产量最高,每袋达到269 g,比对照提高11.16%（P 〈0.01）,其子实体中磷、钾、钠、钙、镁、铁、锌及锰含量均比对照高,且子实体中铅、镉、砷和汞含量符合绿色食品标准。

英文摘要：

A mixture consisting of 50% rice chaff and 50% sawdust,supplemented with a live microbial preparation （Lingpaifang No.Ⅰ diluted 1000-fold to adjust the overall water concentration to 45%）,was fermented for 2-3 days at 70 ℃ and then used as bedding material in a pig house.After 18 months,the spent litter remaining was incorporated into ten growth substrate formulae used to cultivate Auricularia polytricha . One of these （Substrate A3 consisting of 49% sawdust,30% spent litter,11% cotton seed hulls,7% wheat bran,1% gypsum,1% lime,1% CaCO3 and 63% water）produced the highest fruit body yield of 269 g/bag, which was higher of 11.16% （P 〈0.01）compared to controls.P,K,Na,Ca,Mg,Fe and Zn levels in fruit bodies were higher than controls,and Pb,Cd,As and Hg levels in fruit bodies were lower than the safe thresholds defined for Green Food.
