摘要
为了充分利用蚕桑生产中废弃的桑枝资源以及扩展食用菌产业的原材料来源,笔者进行了利用桑枝栽培长根菇的试验,结果表明,长根菇在桑木屑比例为70%~97%范围内的菌丝生长较好,培养基配方中桑枝比例为75%~80%左右,生长速度较快,可达1.96~2.63 mm/d。产量测定表明,从2011年6月开始出菇,至9月结束,期间每隔2~3天既出产1潮次,表现出子实体生长发育较快,主要的生长季节在夏季,并且产量较高,生物学效率高,可达75%~84.4%,子实体高大挺拔,菌盖较大较厚。经济效益分析表明每种植100 kg原料可获得纯经济收入300元以上,而且随着种植规模的扩大呈现出较好的经济效益。因此,在中国蚕区利用桑枝资源栽培食用菌,特别夏季栽培长根菇具有良好的应用前景。
In order to fully utilize mulberry twigs resources in silk production and expand sources of raw materials in edible fungus production, the mushroom cultivation experiments for Oudemansiella radicata with different methods and proportions of mulberry branch powder was studied. The mulberry twigs powder proportion was from 75%-80% in the formula of mushroom growth medium, the mycelia growth rate was faster than other media, it might reach the 1.96-2.63 ram/date. Ouclemansiella radicata yield determination showed that, beginning from June of 2011 for the first yield fluctuation to September for the end, every 2 to 3 days harvests one time in the period. The fruit body growth and development was faster in the summer than other seasons, and higher yield and biological efficiency could reach 75%-84.4%, fruiting body was higher, thicker in pileus and larger and thicker for its caps. Economic analysis showed that 100 kg raw material could be obtain net economic income more than ~300 , and as to expand the planting scale showed better economic benefits. The experimental results showed that the mulberry branches as a kind of raw materials for mushroom production was a best way of comprehensive utilization in mulberry and mushroom production, it saved the cost of production and increased benefits, especially production of Oudemansiella radicata in the summer and had broad application prospects.
