以从兰科植物分离出的内生真菌与大花蕙兰接种，均能形成菌根，其中ＧＣ９４１和ＧＣ９４５两种菌只侵染根的表皮细胞，在细胞内呈菌丝结结构，而ＧＣ９４３菌在侵染前期同前两种真菌，后期菌丝可部分侵染皮层细胞，并呈疏松的分枝状结构。３种内生真菌可使幼苗茎叶干重比增施矿质营养但不接种真菌的处理（ＣＫ２）提高１７３．２％～２５０．１％，并对植株吸收Ｎ、Ｐ、Ｋ养分有促进作用，其中ＧＣ９４５菌使幼苗吸收Ｎ和Ｋ的量比ＣＫ２处理分别提高了１７５．７％和９７．５％；ＧＣ９４３菌使植株对Ｐ的吸收量比ＣＫ２处理提高了７倍。此结果可为研制兰花专用基质提供参考。
Inoculation with endophytic fungi isolated from orchid plants and Cymbidium, can form mycorrhiza, GC941 and GC945 two kinds of bacteria invade the root epidermal cells in the cell mycelium structure, and GC943 The bacteria in the pre-infection with the former two kinds of fungi, late hyphae can partially invade cortical cells, and showed a loose branched structure. The three kinds of endophytic fungi could increase the dry weight of stems and leaves of seedlings by 173.2% ~ 250.1% compared with the treatments of increasing mineral nutrition but not inoculation fungi (CK2), and promoted the absorption of N, P and K nutrients , In which GC945 bacteria increased the amount of N and K absorbed by seedlings by 175.7% and 97.5%, respectively, compared with CK2 treatment. GC943 increased the P uptake by plants by 7 times than CK2 treatment. This result can provide a reference for the development of orchid matrix.
