目前国内有不少单位,以棉纺厂的下脚料——废棉渣作原料,利用人防工事来栽培平菇。有关废棉渣栽培平菇的技术问题,虽有一些方面需要继续探索,但总的来说在逐步提高,日臻完善,各地已出现不少高产典型。如我省邵阳市汽车配件厂,废棉渣栽平菇的生物学效率,曾高达250％。然而也有不少单位产量甚低,甚至失败的。究其原因,主要是由于对废 At present, there are many units in China that take the waste of cotton mills as raw material and use cotton clinker as raw material to grow Mushrooms by means of air defense. Although some aspects need to be explored on the technical issues of waste cotton residue cultivation of Pleurotus ostreatus, generally speaking, it is gradually improving and improving. Many high-yield typicals have appeared in various places. Such as our province Shaoyang City Auto Parts Factory, waste cotton residue planted mushroom biological efficiency, once as high as 250%. However, there are also many units that produce very little or even fail. The reason is mainly due to waste
