摘要
本试验通过棉秆替代锯末、稻壳制作猪垫料发酵床,底物组合为棉秆65%、锯末7%、稻壳28%;采用4种培养基(PDA培养基(PDA)、萨氏培养基(S)、牛氏培养基(N)、羧甲基纤维素钠培养基(SK))从不同原料(腐烂棉杆、腐朽木、腐草、猪粪、猪场发酵床)中提取出5种菌株,分别为PDAs、Sf、Nf、Nb、SKm,利用微生物学技术,从底物组合、菌种配比和发酵床承载能力3部分内容进行研究。结果表明,5种菌株的配比为4∶2∶2∶1∶1,菌种添加量为10%,每头猪所占面积为1.2m2的制作方式,能使发酵床的使用效果达到最佳,为产棉地区利用棉秆制作发酵床垫料提供参考。
This study was to make fermentation bed by the cotton stalk instead of sawdust and rice husk, the combination of substrate included cotton stalk 65%, sawdust 7 %, rice husk 28 %, using 4 kinds of media （PDA medium （PDA）, sabouraud me- dium （S）,niushi medium （N）,carboxymethyl cellulose sodium medium（SK）） and extracted five kinds of strains from different materials （cotton stalk rot, decay wood, decaying vegetation, manure, pig fermentation bed）, the subject worked on of three ex- periments from the combination of substrate, the ratio of strain and the carrying capacity of fermentation bed using microbiology technology, The results showed that the ratio of PDAs ： Sf ： Nf ： Nb ： SKm was 4 ： 2 ： 2 ：1 = 1, adding strains was 10$, each pig＇s share of area was 1.2 m2 ,it was the best to use of the fermentation bed and paid a solid base for the production of fermentation bed with cotton stalk.
