引言 1983～84年,温哥华不列颠哥伦比亚研究中心,研究了如何用纸浆厂淤泥栽凤尾菇,且已达到商品生产阶段。由于是利用工业废弃物作栽培材料,菇农都担心凤尾菇会污染重金属。为此,对典型的漂白牛皮纸浆厂纤维质淤泥及用其栽培的凤尾菇进行了分析,以确定其矿物质及重金属含量。本文总结了分析数据并进行了比较。 Introduction In 1983-84, the British Columbia Research Center in Vancouver studied how to grow Pleurotus ostreatus with silt in pulp mills and reached the commercial production stage. Because it is the use of industrial waste for cultivation of materials, Mushroom farmers are worried about mushrooms will pollute heavy metals. To this end, the typical bleached kraft pulp mill sludge and its use of mushroom cultivation was analyzed to determine its mineral and heavy metal content. This article summarizes the analysis data and compares them.
