搔菌对北虫草生长的影响

摘要

Objective North Cordyceps is as valuable as the wild Cordyceps nensis on medicinal value, nutrients, and trace element contents, which attracts lots of re-searchers to explore the cultivation method. In order to master the best way to in-crease output, an experiment was conducted [Methods] To conclude the result, 100 boxes were chosen, of which 50 boxes were treated with fungi-scratching in the same condition, based on comparisons of color changing and fruit body. [Results] The stroma have consistent length in good order ,but there is 1 box of scratching happened infections after operating. [Conclusion] Scratching can promote mycelium turning color better, shorter the cycle of fruiting, and prevent the phenomenon of "aside grass" and "no grass" effectively,al of this can make the North Cordyceps grow more dense and neatly.%北虫草在药用价值、营养成分、微量元素含量等方面可与野生的冬虫夏草相媲美，因而吸引很多的科研工作者对栽培方法进行探究。本文就搔菌一环节对北虫草生长做了认真细致的试验，得出如下结论：搔菌可以更好的促进菌丝转色，缩短出草周期，并且可以有效的防止“边草”和“不出草”现象的发生，使虫草子实体生长的更加茂密、整齐。
