摘　　要：以大葱品种青叶1号为试材,探讨接种丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)对葱苗生长及矿质元素吸收的影响。结果表明,AMF与大葱根系形成了良好且稳定的共生关系,接种45 d后根段的侵染率达到83.3%。与未接种处理(CK)相比,接种AMF显著提高了葱苗的株高、假茎长、茎粗、地上部和地下部的干鲜质量、根系活力、根系表面积、光合色素含量,以及矿质营养元素N、P、K和Mn的含量,促进了健壮葱苗的培育。Taking the green onion variety‘Qingye No.1’as test material,the effects of inoculation with arbuscular mycorrhizal fungi(AMF)on the growth and mineral element absorption of green onion seedlings were studied.The results showed that AMF could form a good and stable symbiotic relationship with the onion root system,and the root mycorrhizal infection rate was 83.3%in 45 days seedlings.Compared with control(CK),inoculation with AMF significantly increased the plant height,pseudostem length,stem thickness,fresh and dry weight in both onion seedlings and roots,the root activity,root surface area,leaf photosynthetic pigment and nutrient mineral elements contents of N,P,K,and Mn in onion seedlings.These results suggest that inoculation with AMF is helpful in breeding robust green onion seedlings.
