木麻黄木屑栽培平菇的研究 总被引:1,自引:0,他引:1
以速生阔叶树种木麻黄作为原料 ,以其它相混杂的阔叶树种 (称之为杂木 )为对照 ,进行栽培平菇的研究。结果表明 :以木屑和棉籽壳各半为原料的配方适合于平菇的栽培。以木麻黄为主要原料栽培平菇的平均产量是每袋 1 3 65kg,比以杂木为主要原料栽培平菇的平均产量每袋 1 0 3 2kg高出 0 3 3 3kg,感染率也高出8 72 % ,而生物效率相差不多 ,分别是 1 0 6 0 61 %和 1 0 3 82 3 % ;用木麻黄木屑栽培出的平菇与用杂木木屑栽培出的平菇在蛋白质、糖类、脂肪、纤维素、氨基酸含量及氨基酸种类方面极为相近 ,这充分说明了木麻黄和其它阔叶树一样 ,可作为平菇等食用菌栽培的原料。以木麻黄为原料在沿海地区栽培平菇等食用菌取得成功 ,是利用沿海防护林速生树种木麻黄作为食用菌林上的一个创新。 相似文献

Sound absorption capability and mechanical properties of a composite rice hull and sawdust board 总被引:1,自引:0,他引:1
Chun-Won Kang Seung-Won Oh Tae-Bong Lee Wook Kang Junji Matsumura 《Journal of Wood Science》2012,58(3):273-278
Rice hull–sawdust composite boards were manufactured for sound-absorbing boards in construction. The manufacturing parameters were target density (400, 500, 600, and 700?kg/m3) and rice hull content as percent weight of rice hull/sawdust/phenol resin (10/80/10, 20/70/10, 30/60/10, and 40/50/10). Commercial gypsum board and fiberboard were also used as comparative sound-absorbing materials. The average modulus of rupture (MOR) of the board with a density of 700?kg/m3 and rice hull mixing ratio of 10% was 8.6?MPa, and that of the board with a 400?kg/m3 board density and a rice hull mixing ratio of 40% was 2.2?MPa. The MOR increased with increasing board density or decreasing rice hull mixing ratio. The sound absorption coefficients of some boards (400?kg/m3 and 10%, 500?kg/m3 and 30%, and 500?kg/m3 and 40%) were better than those of the commercial 11-mm-thick gypsum board. Thus, it is concluded that rice hull–sawdust composite boards may be implemented as sound-absorbing barriers in construction due to their high sound absorption coefficients. 相似文献

This study formed part of an effort to improve the quality of dried shiitake mushroom [Lentinula edodes (Berk.) Pegler], in accordance with consumer preferences, and deals with the search for substances that increase the odorous
component content. From analysis of sulfur and sulfur-containing substances in the culture substrate, rice bran was found
to be the main source of sulfur, and 75% of this was present as cysteine and methionine. The sulfur-containing substances
were added to a sawdust medium containing only rice bran and sawdust as a substrate; shiitake mushrooms were cultivated in
the medium, the fruiting bodies were dried, and the 1,2,4-trithiolane content in the fruiting bodies was measured as an indicator
of the odorous compounds. Of the sulfur-containing substances, those that increased odorous compounds the most were cysteine
and methionine. The efficiency of cysteine in this regard was higher than that of methionine. It was also noted that the amount
of glutamic acid increased the odorous compounds in combination with cysteine and methionine. Furthermore, the addition of
both amino acids and glutamic acid had no negative effect on the yield. These results showed that it is possible to produce
dried shiitake mushrooms with a smell suitable for particular consumer preferences. 相似文献
