VA菌根对酸枣实生苗吸收土壤磷锌铁元素的影响

The effects of VA mycorrhizae on P, Zn, Fe absorption of wild jujube (Zizyphus spinosus Hu) seedlings

试验利用三室隔网盆栽方法 ,将土壤分为根系吸收区和菌丝吸收区 ,研究了VA菌根对酸枣实生苗生长、吸收土壤磷、锌、铁元素的影响。结果表明 ,VA菌根促进了植株对土壤磷、锌的吸收。菌丝吸磷量随外室施磷浓度增加而增加。

Pot experiments were carried out to study the effect of VAM on P, Zn, Fe absorption of wild jujube (Zizyphus spinosus Hu) seedlings. The pots had three compartments, a central compartment for root growth separated by 30μm mesh nets from two outer compartments for mycorrhizal hyphae growth. The results showed that VAM could improve P and Zn amount of plant. With the increase of P concentration in the outer compartments soil, hyphal uptake of P increased. But the effect of VAM colonization on Fe-concentration in plant was not definite.
