【中文摘要】 本文研究了木屑培养基中米糠和麦麸两种辅料对香菇生长发育的影响。结果表明:米糠含量高的培养基,其绝对生物学效率、培养基失重、呼吸消耗、木质纤维素降解量均高于米糠含量低的培养基;麦麸更适合作栽培香菇的辅料,20%的麦麸具有30％米糠基本相同的生理功能;培养基的C/N在栽培过程中不断下降,适当增加氮源可降低培养基的C/N,具有提高香菇产量的作用。
【英文摘要】 Effect of two kinds of supplements-- rice bran and wheat bran in sawdustmedium on the physiology of L. edodes was investigated. The results showed that as far as the shiitake mushroom growing on the medium with high content of rice bran, the yield of fruitbodies, the amount of lignocellulose decomposed, the absolute biological efficiency, the weight reduction of dry medium and the consumption of respiration were all higher than those of the same shiitake mushroom growing on the medium with low content of rice bran; that wheat bran was more suitable to be used as supplements of L. edodes medium and sawdust medium supplemented with 20% wheat bran or 30% rice bran had almost the same effect on mycelial growth; and that C/N of the medium decreased progressively during the cultivation of L. edodes and the yield of fruitbodies could be increased when nitrogen was added to the medium for reducing C/N.
