草菇生长快,周期短,是夏季生产的最好菇种。其不足之处是产量较低,生物效率只有20—40%,经济效益不高。为此,我们于1987—1988年进行了用种过平菇的棉籽壳废料(以下简称菌糠)再种草菇的试验,现将1988年试验情况报告如下:(一)原料处理和配方:原料有春栽平菇的菌糠、棉籽壳、麦秸和麸皮。菌糠去除污染部分后粉碎曝晒2天,以杀死平菇老菌丝;棉籽壳也曝晒2天,麦秸经滚压破碎,用5%石灰水浸1天再堆积发酵4天(中间倒翻一次),设四个配方:(1)菌糠12.2公斤,麸皮300 Straw mushroom grow fast, short cycle, is the best summer mushroom production. The disadvantage is the low yield, biological efficiency of only 20-40%, economic efficiency is not high. Therefore, in 1987-1988, we carried out the experiment of re-growing straw mushrooms with the waste of cottonseed shells planted with Pleurotus ostreatus (hereinafter referred to as the mushroom bran). The test results of 1988 are reported as follows: (I) Raw material handling and formulation: Raw materials are mushrooms mushroom fungus bran, cottonseed shells, wheat straw and bran. After the fungus bran was removed from the contaminated part, it was crushed and exposed for 2 days to kill the old mycelium of Pleurotus ostreatus. The cottonseed shell was also exposed for 2 days. The wheat straw was crushed by rolling and then fermented for 4 days with 5% Once), set four formula: (1) 12.2 kilograms bran bran, bran 300
