前言在苗圃和人工林地接种菌根真菌能促进辐射松(Pinus sadiata D.Don)的生长,这已经得到反复证明。但这种促进作用和天然菌根真菌的存在及引进这类菌根有关。当一个新苗圃建立时,尤其是如果这个新苗圃远离正在生长的人工林地或老圃地,或一个老圃地经过土壤薰蒸消毒处理后,就更应该想到用有效的菌根真菌进行土壤接种。用担子菌纲的菌根真菌在 Introduction The inoculation of mycorrhizal fungi in nurseries and plantations to promote Pinus sadiata D. Don has been repeatedly demonstrated. However, this facilitation is related to the presence of natural mycorrhizal fungi and the introduction of these mycorrhizae. When a new nursery is established, especially if the new nursery is far away from the growing plantation or nursery or fumigating the soil in a nursery, even more thought should be given to soil inoculation with effective mycorrhizal fungi .
