The experiment was conducted to study the effects of different treatments on the survival rate, growth rate, leaf traits, dry matter content of 5-year-old Pinus densiflora var. zhangwuensis, including compound microbial agent, ABT-3 rooting powder and a 1:1 mixture of the two treatments.[Results] When applying the ABT-3 rooting powder alone, the ground diameter, underground biomass, afforestation survival rate and afforestation cost were the best; when applying compound microbial agents alone, seedling height, ground diameter, annual average growth, dry matter quality on the ground, the total dry matter quality, needle thickness, needle area and chlorophyll content were the best of all; The measured indexes of the mixed treatment were lower than the single treatment, but higher than the control treatment.[Conclusion] In the afforestation of Pinus densiflora var. zhangwuensis in Beijing City, in addition to the conventional tending management, the use of compound microbial agents may not only improve the survival rate of afforestation, but also promote the growth and development of seedlings, accelerate the pace of forestation, and improve the stand quality, and ultimately achieve the goal of improving the environment of the Beijing City. %R 10.13961/j.cnki.stbctb.2019.05.013 %U http://stbctb.alljournal.com.cn/stbctb/home %1 JIS Version 3.0.0
