Experiments were carried out to test the viability of growing Pleurotus geesteranus on media containing varying amounts of crushed water hyacinth slices, which were soaked in pig farm biogas fluid and dried. The water hyacinth material was utilized to substitute sawdust in the media for mushroom cultivation. Mushroom fruiting bodies harvested were evaluated for yield, amino acid and heavy metal contents. Among the eight treatment groups, the greatest yield and highest amino acid content in the mushrooms were obtained when the proportions of water hyacinth and sawdust in the medium were equal. The concentrations of heavy metals, Hg, Pb and Cd, in most of the present mushroom samples did not exceed the maximum allowed levels according to the limits set forth by the food hygienic and safety regulations for edible mushrooms in China. The proposed waste utilization of water hyacinth could conceivably benefit the environment in various aspects including conservation of forest by reducing the demand on natural woods for mushroom production.
进行了实验以测试在含有不同量粉碎的水葫芦片的培养基上生长 Pleurotus geesteranus 的可行性，这些水葫芦片浸泡在养猪场沼气液中并干燥。水葫芦材料被用于替代培养基中的木屑进行蘑菇栽培。收获的蘑菇子实体用于评估产量、氨基酸和重金属含量。在八个处理组中，当培养基中水葫芦和木屑的比例相同时，蘑菇的产量最大，氨基酸含量最高。根据中国食用菌卫生和安全法规规定的限量，大多数现有蘑菇样品中的重金属 Hg、Pb 和 Cd 浓度未超过允许的最高水平。水葫芦的这种废物利用方案可以在各个方面有益于环境，包括通过减少对天然木材的需求来保护森林，从而有利于蘑菇生产。
