文章对引进的 2 0个香菇菌种 ,从菌丝的发育、周期产量及质量等方面进行了木段栽培对比筛选试验。经小试到中试研究表明 ,5号和 10号菌株在营养生长、周期产量、商品化率和花菇率等指标上明显优于其他菌株 ,其中 5号菌株周期产干品香菇 2 0 .4kg/m3,花菇率 4 5% ;10号菌株周期产量达 19.8kg/m3,花菇率 55%。是适宜辽宁省东部山区木段栽培的优良菌株 Articles of the introduction of 20 mushroom strains, from the mycelium development, cycle yield and quality aspects of the wood section cultivation comparison screening test. The pilot-scale pilot study showed that the strains No. 5 and No. 10 were significantly better than other strains in the indicators of vegetative growth, periodical yield, commercialization rate and mushroom growth rate, among which No. 5 strain periodically produced dried mushrooms 20. 4kg / m3, Mushroom rate 45%; 10 strains of the cycle of production of 19.8kg / m3, mushroom rate of 55%. It is an excellent strain suitable for cultivation of wood blocks in the eastern mountainous area of ​​Liaoning Province
