摘  要：
将废筷子(作增氧辅料)分别捆扎成4.0%、6.0%、8.0%和10.0%的孔隙度较大的纺锤状芯,分装于以锯末为主料的栽培料中心以增大供氧量,使平菇菌丝体对主、辅料中营养物质的分解、吸收、利用与转化处于最佳代谢状态,达到快速、健壮生长的目的。结果表明:试验组比对照组发菌期缩短2.4～7.3d;鲜菇产量增加1.8～6.6kg/kg(干料);生物效率提高6.0%～21.1%。经方差分析,各处理组间的发菌期和生物效率均在0.05水平上有差异;与对照组相比,在0.01水平上有差异。

摘  要：
Volvaria belongs to aerobic and wood-rotten type of edible fungus. Disused chopsticks(as supplement materials to increase oxygen), were separately enlaced into spindle shapes according to different degree of porosities: 4.0 %, 6.0 % and 8.0 %, and then were packed in the core of planting materials mainly made of sawdust. At the same time, the oxygen supply amount was increased so that volvaria mycelium can be in best situation to decompose, absorb, utilize and transform the nutrition from main and supplemental materials. As a result, the growth of mycelium can be quicker and stronger. The experimental results showed: volvaria growing period of tested group was 2.4～7.3 days shorter than the normal group. At the same time, the output of fresh volvaria was increased by 60~211 g, and the biological efficiency was improved by 6.0 %~21.1 %. Variance analysis concluded that volvaria growing period and its biological efficiency had great differences. Compared with LSD, there was notably difference between tested group and normal group. Thus, the air permeability and oxygen supply amount of planting material were important factors affecting volvaria growth and its biological efficiency.
