凤眼莲的机械处理及其栽培草菇试验

Test on mechanical processing of exotic invasive plants-water hyacinth for straw mushroom cultivation

凤眼莲是外来入侵的有害物种,在我国南方水域常年爆发成灾,合理资源化利用是凤眼莲避害趋利的重要方向。介绍经新研制的专用脱水破碎设备每小时可以处理新鲜凤眼莲10吨以上。处理后的凤眼莲适合栽培草菇,以48%添加量配方栽培草菇的试验结果,其菌丝及子实体生长正常,生物转化率为16.4%,其产品的主要重金属含量均符合国家食品安全标准和农业绿色食用菌标准。

The southern area of China especially Guangdong province has been troubled with water hyacinth for many years, resource utilization of water hyacinth straw is one of the important direction of solving its outbreak. In this paper, mechanical processing of water hyacinth for straw mushroom cultivation was tested. The results showed that the crushing equipment can handle 10 tons（fresh water hyacinth）per hour, the straw mushroom grew well on the substrate with 48% of crushed water hyacinth, the biological efficiency was 16.4%.The main heavy metals（As、Pb、Hg） content in the mushroom are accord with national food safety standards.The water hyacinth can be used as a raw material for straw mushroom cultivation.
