[Objective] North Cordyceps is as valuable as the wild Cordyceps nensis on medicinal value, nutrients, and trace element contents, which attracts lots of researchers to explore the cultivation method. In order to master the best way to increase output, an experiment was conducted [Methods] To conclude the result, 100 boxes were chosen, of which 50 boxes were treated with fungiscratching 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.
