植物的生长环境除了物理环境和化学环境外,还包括生物环境,某些植物在长期的生物进化过程中与土壤中某些真菌形成了互惠互利的菌根共生体。菌根可分为外生菌根和内生菌根两类。
In addition to the physical environment and the chemical environment, the plant growth environment includes the biological environment. Some plants form a mutually beneficial mycorrhizal symbiont with some fungi in the soil during long-term biological evolution. Mycorrhizal can be divided into two types of ectomycorrhizas and endomycorrhiza.
