采用单因素试验和主要因素正交试验，对经12C6+重离子辐照选育的北冬虫夏草高产菌株G5的人工栽培最佳条件进行研究。结果表明，北虫草高产菌株G5栽培的最佳培养基为大米80%+蚕蛹粉20%，培养基料水比为1 ∶ 1.5；菌丝和子实体生长的最佳温度分别为23 ℃和21 ℃；最佳散射光照强度为500 Lx。

The optimal conditions for artificial cultivation of high producing strain Cordyceps militaris G5 irradiated by heavy ion beams 12C6+ are studied by single factor experiments and orthogonal test on main factors. The result shows that the optimum condition for high producing strain C. militaris G5 cultivation is as follows: the best mediums are both the 80% rice and 20% silkworm chrysalis； material-water ration of the medium is 1 ∶ 1.5； the optimum temperature is 23 ℃ for proliferating mycelia and 21℃ for fruiting bodies growth； and the best lighting intensity is 500 Lx.
