摘要
以金针菇航天诱变种(航金1号、航金2号)和亲本"江山白"为试验材料,通过不同条件栽培试验,对它们的耐高温性和早熟性进行了比较。结果表明:两个航天诱变种与亲本相比,表现出较好的耐高温和提早成熟的特性,其中又以航金1号最佳。同时研究发现,在30℃的高温下,航金1号和航金2号菌丝体仍可正常生长,而对照却出现老化现象;在18℃的相对高温下,航金1号和航金2号可正常出菇,而对照极少出菇。通过不同的栽培配方比较发现,以配方为棉籽壳34%,杂木屑34%,麦麸25%,玉米粉5%,石膏1%,蔗糖1%的混合培养料栽培出的金针菇产量较高。金针菇航金1号菌株具有重要的生产价值和意义。
In this experiment,the research materials were two space mutant strains of Flammulina velutipes（Fr.）Sing.（hangjin Ⅰ and hangjin Ⅱ） and the ground control check strain（Jiangshan bai）.Through different experiments,the thermostability and early-maturity of the three strains were compared,and it was found that the thermastability and early-maturity of hangjin Ⅰ and hangjin Ⅱ were better than those of jiangshan.Both of their mycelium could grow normally under the temperature of 30℃,and they are capable of fruting under the relatively high temperature of 18℃,and hangjin Ⅰ performed better than hangjin Ⅱ.Besides,all of the three fungus strains were cultivated in different mediums,and it turned out that they gave a good yield by using the mixed medium consisting of cotton seed hull（34%）,mixed wood scraps（34%）,wheat bran（25%）,cornmeal（5%）,gypsum（1%） and sucrose（1%）.Hangjin Ⅰ has important value in the production of Flammulina velutipes.
