: The Japanese larch ectomycorrhizal fungi single solid fungi improved to a variety of nutrients containing compound bacteria agents, studies have shown that the optimum amount of compound fungicide was 22.5g / m2, prompting sowing seedlings, transplanting seedlings The seedling height, root diameter, lateral root number and primary seedling rate increased by 26.0% and 40.1%, 37.1% and 40.0%, 41.0% and 35.7%, 12.5% and 12% .6%. The survival rate and preservation rate of afforestation were increased by 11.9% and 14.5% respectively compared with the control. The tree height of 1-4 year-old saplings was increased by 18.5% -2.33% and 13.9% -33.9% compared with the control. By 6a cultivation of mycorrhizal seedlings and afforestation, can benefit 32180000 yuan
