柑桔茂盛果园的土壤中都自然发生有益的菌根真菌,如果管理不善,将破坏或抑制这种微生物,能引起柑桔树营养不良和衰弱。很多事例证明:某一些菌根真菌对植物生长的刺激作用大大优越于其他菌根真菌,但这种优异的真菌只有在土壤能使其正常繁殖才是有益的;用特定菌根真菌品种接种到植株上,要在某些条件下才能有利。孢囊丛状菌根在实验条件下,作温室及大田土壤接种已 Beneficial mycorrhizal fungi naturally occur in the soil of citrus orchards, which, if poorly managed, can destroy or inhibit such microorganisms and can cause malnutrition and debilitating citrus trees. There are many examples that show that some mycorrhizal fungi are significantly superior to other mycorrhizal fungi in stimulating plant growth, but this excellent fungus is beneficial only when the soil allows it to reproduce normally; inoculation with specific mycorrhizal fungal species Plants, to be beneficial under certain conditions. Podocyst arbuscular mycorrhizal in laboratory conditions, for greenhouse and field soil inoculation has been
