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。
Based on the improvement of overburden soil in a large dump of a mine and referring to the successful experience of comprehensive utilization of domestic mushroom waste, the experimental field was studied. The results showed that the mushroom waste played an important role in improving soil water content and water storage in overburden soil, improving grain size and grading of soil particles, increasing soil organic matter content, optimizing soil pH value and increasing microbial content. Soybean planting test further proved Feasibility of mushroom waste improving soil fertility. The recovery and utilization of mushroom waste not only provides a good environment for the reclamation of plants, but also achieves turning waste into treasure, avoiding pollution to the surrounding environment and guaranteeing the reclamation and greening of the dump.
