【中文摘要】 本文研究了雜木屑培養(yǎng)基中麥麩和米糠兩種輔料對栽培香菇的影響。試驗結果表明:米糠含量高的培養(yǎng)基,其絕對生物學效率、培養(yǎng)基失重、呼吸消耗、木質(zhì)纖維素降解量均高于米糠含量低的培養(yǎng)基;麥麩更適合作栽培香菇的輔料,20%的麥麩具有30%米糠基本相同的生理功能;培養(yǎng)基的C/N在栽培過程中不斷下降,適當增加氮源可降低培養(yǎng)基的C/N,具有提高香菇產(chǎn)量的作用。

【英文摘要】 A research on the effect of wheat bran and rice bran in broad-leaf tree sawdust medium on the growth of L. edodes was conducted. The result showed that when medium was added with high content of rice bran, the absolute biological efficiency, medium weight reduction, respiration consumption and the lignocellulose reduction of the medium were higher than that added with low content of rice bran. And wheat bran was proved to be a kind of more suitable subsidiary. Medium with 20% wheat bran showed the same physiological function as that with 30% rice bran. While the ratio of C/N in medium decreased continuously during the cultivation of L. edodes, so appropriate increment of nitrogen source could reduce C/N in medium and improve the yield of L. edodes.
