蘑菇废料在矿山排土场覆土层改良中的综合利用

摘要

Based on soil improvement in a large mine waste dump, combining successful experience of domestic mushroom waste utilization, a related field experiment was conducted. The results show that the mushroom cultivation waste played an important role in raising soil water content and water storage ability, improving organic matter content, microbial content, and optimizing soil particle size, pH value. Soybean planting test further proves the feasibility of using mushroom waste to improve soil fertility. Mushroom waste recycling and utilization not only provide a better environment for plants growth, but also achieve a "turning waste into treasure", avoid surroundings pollution.%以某矿山大型排土场覆土层改良为依据,参考国内蘑菇废料综合利用的成功经验,进行了试验田研究.结果表明:蘑菇废料对于提高覆土层土壤含水量、蓄水性,改善土壤颗粒粒级级配,提高土壤有机质含量,优化土壤pH值,提高微生物含量都具有重要作用；大豆种植试验也进一步证明了蘑菇废料改良土壤肥力的可行性.蘑菇废料的回收利用不仅为复垦植物提供良好的成长环境,而且也实现了变废为宝,避免其对周围环境造成污染,为该矿山排土场复垦、绿化提供了保障.
