在无施肥区,由于菌根的存在,生长量菌根多的试区比少的高1.5倍,吸收磷高3倍,钾高1.4倍,氮高1.3倍.另外,Kramer Harley等对松和几种树木的试验表明,有菌根的比无菌根的在根重乃至根系平均表面积方面对磷、钙、钠、其他无机盐类吸收总的都增加,据Hatch试验,有菌根的比无菌根的吸取氮多86%,钾75 %,磷234%.菌根吸收无机盐类过程,因测定困难,现在还不清楚,但Melim等用同位素对菌根吸收磷进行大量观察判定,菌根对无机盐类进入根部起到了很大的作用.菌根的代谢功能大,吸收盐类能力高
In the non-fertilization area, because of the presence of mycorrhizae, the test area with more mycorrhizal growth was 1.5 times higher than that with less, three times higher phosphorus was absorbed, 1.4 times higher potassium and 1.3 times higher nitrogen.In addition, Kramer Harley et al. Tests of several trees showed that the uptake of phosphorus, calcium, sodium and other inorganic salts in the root mass and even the root mean surface area of mycorrhizal than the mycorrhizal root increased in general, according to the Hatch test, the mycorrhizal ratio Mycorrhizal absorption of inorganic salts 86%, 75% potassium, 234% of phosphorus absorption of mycorrhizal inorganic salts, due to the determination of difficulties, it is unclear, but Melim and other isotopes of mycorrhizal phosphorus to be observed a large number of observations, Mycorrhizal inorganic salts into the root has played a significant role in the metabolism of mycorrhizal function, the ability to absorb salt high
