Cultivation Technology of Edible Fungus by Reed Straw

Taking reed straw as cultivation substrate, cultivation experiment method was carried out.The effects of different reed straw contents（0%,20%,40% and 60%） and different treatment methods（fermented and unfermented） on the growth and yield of Pleurotus ostreatus and Pleurotus geesteranus were studied, in order to provide reference for the full utilization of straw resources and the exploration of new edible fungi cultivation substrate.The results showed that when the content of reed straw in the substrate was 20%,the covering time of Pleurotus ostreatus mycelia was（26.0±0.6）d, the mycelia were white and vigorous, and the mushroom was in good condition.At this time, the dry weight and crude protein content of oyster mushroom were（19.5±0.8）g and 1.4 g·（100g）^-1.The time of covering bags of Pleurotus geesteranus on sawdust culture substrate was the shortest（reed content was 0%）.When the content of reed was 20%,the mycelia grew white and dense, the mushroom emerged well, and the dry weight and crude protein content were the best（18.3±0.7）g and（1.7±0.001）g·（100g）^-1,respectively.In addition, Pleurotus ostreatus and Pleurotus pleurotus cultivated with fermented reed straw were superior to those cultivated with unfermented reed straw in all aspects.
