适于吉林地区的6株榆黄蘑液体菌种品比试验

Comparison Experiment of Six Pleurotus citrinopileatus Varieties of Liquid Strain in Jilin

为了筛选出适合吉林地区栽培的榆黄蘑品种,对6株榆黄蘑(GZ1、HL1、HL2、LN1、JL1、HL3)液体菌种的发菌时间、满袋天数、菌盖直径、菌柄长度等指标进行了比较分析,结果表明,6株榆黄蘑液体菌种中,HL2发菌所需时间较短且菌盖直径较长;同时对各菌株在2种不同栽培种培养料配方下产量及生物转化率进行分析,结果表明,HL2的单袋产量和生物转化率显著高于其他菌株,且其在以玉米芯和木屑为主的配方二中产量(328.27 g·袋^-1)及生物转化效率(96.55%)均高于以玉米芯为主的配方一的产量(255.87 g·袋^-1)及生物转化效率(88.23%)。综上,来自于黑龙江农科院牡丹分院的HL2适合在吉林地区进行栽培,其相对较适培养基配方为64%玉米芯、20%木屑、15%麦麸、1%石灰。

To select the Pleurotus citrinopileatus varieties suitable for planting in Jilin,the indexes including mycelium growth time,pileus diameter and stalk length of 6 Pleurotus citrinopileatus varieties(GZ1,HL1,HL2,LN1,JL1,HL3)were compared and analyzed.The results showed that HL2 took the shorter time in mycelium growth and had the longer pileus diameter than the other five varieties.The yield and biological characters of six varieties were analyzed under two different culture medium formulations.The results showed that both the yield and biological conversion rate of HL2 variety were significantly higher than that of the other five varieties.The yield and biological conversion rate of HL2 variety in formula 2 basing on corn cob and sawdust were 328.27 g per bag and 96.55%,and the two values of fomula 1 basing on corn cob were 255.87 g per bag and 88.23%,indicating that the fomula 2 was better than the fomula 1.Consequently,HL2 which is from Heilongjiang academy of agricultural sciences peony branch is most suitable for cultivation in Jilin area,and the relative suitable medium is composed of 64%corn cob,20%sawdust,15%wheat bran and 1%lime.
