摘要/Abstract

摘要： 采用红绒盖牛肝菌、劣味乳菇、紫金蜡蘑、美味牛肝菌和2株彩色豆马勃（分别编号Pt1、Pt2）接种895杨扦插苗，发现菌根真菌对895杨的矿质营养吸收有显著的影响。6种菌根真菌处理的895杨树体内铵态氮和硝态氮含量均有不同程度的增加，提高了杨树根系活力，其中红绒盖牛肝菌、劣味乳菇、美味牛肝菌和Pt 2处理的895杨体内硝酸还原酶含量、硝态氮含量以及氮、磷的吸收均显著高于对照；接种红绒盖牛肝菌、劣味乳菇、美味牛肝菌的895杨根系活力提高较为显著，其中接种美味牛肝菌的895杨，根系活力最强。接种紫金蜡蘑、Pt1处理的杨树对于磷的吸收显著高于对照；各处理下钾元素含量差异不显著；接种菌根真菌后895杨体内微量矿质元素含量都有不同程度的增加，铜、铁、锰、锌元素增加量最高，可见优良的外生菌根真菌可以提高宿主对矿质元素吸收的能力。

Abstract: Inoculating ramets of poplar clone 895 with Xerocomus chrysenteron, Lactarius insulsus, Laccaria aemthystea, Boletus edulis, Pisolithus tinctorius 1 and Pisolithus tinctorius 2 indicated that ectomycorrhizal fungi significantly affected the mineral nutrient absorption of poplar clone 895 cutting seedlings. NH+4N, NO-3N content and root activity of poplar clone 895 treated with 6 kinds of ectomycorrhizal fungi were increased variously. Nitrate reductase, NO-3N content and N, P absorption of poplar clone 895 treated with X. chrysenteron, Lactarius insulsus, B. edulis and P. tinctorius 2 were observably higher than control. Root activity of poplar clone 895 treated with X. chrysenteron, Lactarius insulsus and B. edulis were enhanced. B. edulis was the most effective. P absorption of poplar clone 895 treated with Laccaria aemthystea and P. tinctorius 1 was higher than control. After being treated with 6 kinds of ectomycorrhizal fungi, K concentration of poplar 895 changed slightly, but Cu, Fe, Mn, and Zn concentration were highly increased. The results showed that ectomycorrhizal fungi could enhance trace mineral elements absorption of the host.
