为探讨树干茎流和土壤酸化对欧洲水青冈菌根的影响,土壤营养与菌根的关系,我们对土壤的pH、植物可利用态K、Ca、Mg、Mn、酸性树干茎流积累的Pb和溶解的Al以及土壤的全氮、全磷进行了测定,结果表明:土壤矿质营养与菌根之间没有紧密的相关关系;在土壤pH值高于4.0的情况下,酸性树干茎流沉积的Pb和释放的Al离子,对茎流入土区的菌根影响甚微。同时,在这一pH值范围内,土壤酸化对菌根的生长是有利的。
In order to investigate the effects of stem-stem flow and soil acidification on the mycorrhizae in Europe and the relationship between soil nutrition and mycorrhiza, we investigated the effects of soil pH, available K, Ca, Mg, Mn and Pb And dissolved Al and soil total nitrogen and total phosphorus were measured. The results showed that there was no close correlation between soil mineral nutrition and mycorrhiza. When soil pH was above 4.0, Pb and released Al ions have little effect on mycorrhizal flow into the soil where the stems flow into the soil. At the same time, soil acidification is beneficial to mycorrhizal growth within this pH range.
