浆渣是造纸工业的废料,主要含有造纸工艺中未被分解利用的粗纤维及化学残物。此料是造纸原料添加烧碱等物经高温蒸煮分解而来,杂菌含量少,用它来栽培平菇,可不添加多菌灵、生石灰等杀菌药剂。我们于1989年2—3月以石河子造纸厂浆渣作为培养料进行平菇栽培试验,1990年5—10月又进行扩大试验,获得了成功。 供试菌种为佛罗里达平菇(原种用棉籽壳制作并用来播种),培养料为浆渣和棉籽壳,用罐头瓶(10cm×10cm)栽培。
Sludge is the paper industry waste, mainly contains the papermaking process has not been decomposed crude fiber and chemical residues. This material is raw materials such as caustic soda added by the decomposition of high-temperature cooking decomposition, less content of bacteria, use it to grow mushrooms, do not add carbendazim, quicklime and other bactericidal agents. From February to March 1989, we used the pulp residue of Shihezi Paper Mill as the cultivation material for mushroom cultivation. From May to October 1990, we expanded the experiment and obtained the success. The test strain was Florida Pleurotus ostreatus (the original seed was made of cotton seed hulls and used for sowing). The culture material was pulp residue and cottonseed hulls, and was cultivated in a canned bottle (10 cm × 10 cm).
