灵芝培养基的筛选

目的]提高栽培灵芝的产量和品质,为进一步开发、利用灵芝奠定基础。方法]以日本红芝为材料,筛选灵芝的母种培养基、原种培养基和栽培料培养基,并对以棉籽壳为栽培主料的麦麸添加量进行筛选试验,确定灵芝生长的最佳培养基。结果]红芝在棉籽壳母种培养基上生长最快,与其他培养基差异均达极显著水平。原种在玉米粒培养基中生长速度快,菌丝浓密。红芝在棉籽壳加木屑培养基中产量最高,品质好。棉籽壳培养基中麦麸添加量为20%时红芝产量最高,但与麦麸添加量15%的产量无显著差异。结论]综合考虑,灵芝生长的最佳母种培养基是棉籽壳,最佳原种培养基是玉米粒,最佳栽培料培养基是棉籽壳加木屑,最佳麦麸添加量为15%。

Selection of Medium for Ganoderma lucidum

Objective] The research aimed to enhance the yield and quality of cultivated Ganoderma lucidum and lay a foundation for further researching and exploiting G.lucidum.Method] With Japanese G.lucidum as material,the mother culture,original seed and cultivation material media of G.lucidum were screened out,and the screening experiment was conducted on the addition amount of wheat bran in the medium with cottonseed shell as main material so as to confirm the optimum media for the growth of G.lucidum.Result] The growth velocity of G.lucidum on the mother culture medium of cottonseed shell was faster and its difference from that on the other media reached extremely significant level.The original seed grew fast on the corn grain medium and had thick hypha.G.lucidum cultured on the medium of cottonseed shell added sawdust had highest yield and good quality.The G.lucidum yield was highest when the addition amount of wheat bran was 20 % in cottonseed shell medium,but had no significant difference from the yield of adding 15 % wheat bran into cottonseed shell medium.Conclusion] Comprehensively considering,the optimum mother culture medium was cottonseed shell,the optimum original seed medium was corn grain,the optimum cultivation material medium was cottonseed shell added sawdust and the optimum addition amount of wheat bran was 15 % for the growth of G.lucidum.
