目的
2
探究接种不同丛枝菌根(arbuscular mycorrhiza,AM)真菌组合对云南重楼(
Paris polyphylla
var.
yunnanensis
)根际土壤环境的影响。
方法
2
在室温盆载条件下,对种植于灭菌土壤中的云南重楼实生幼苗分别接种12种AM真菌的不同组合,观察不同AM真菌组合的侵染能力及其对云南重楼根系活力、根际土壤环境中养分含量、酶活性及土壤微生物群落结构的影响。
结果
2
接种外源AM真菌对云南重楼根际土壤中AM真菌孢子密度、根系AM真菌侵染率具有调控作用,提高了云南重楼根系活力;外源AM真菌可调节云南重楼根际土壤中的养分含量,提高了根际土壤中总球囊霉素及易提取球囊霉素含量,提高了云南重楼对土壤中速效氮、磷、钾的吸收能力,提高了根际土壤中酶活性,同时改变了土壤微生物的群落结构,提高了细菌/真菌、细菌/放线菌数量比及降低了真菌/放线菌数量比,改善了云南重楼根际土壤环境。
结论
2
不同AM真菌处理组合对云南重楼幼苗根际土壤的理化性质及微生物群落结构存在一定的影响,该研究结果为人工栽培云南重楼提供了技术基础。
Objective
2
To investigate the effect of different arbuscular mycorrhizal (AM) fungi combinations on the rhizospheric environment of
Paris polyphylla
var.
yunnanensis
.
Method
2
The different combinations of 12 arbuscular mycorrhizal (AM) fungi species were inoculated to the seedlings
P. polyphylla
var.
yunnanensis
planted in the sterilized soil under the condition of room temperature to investigate their infection abilities and effects on the root activity,soil nutrient contents,enzyme activities and microbial community structure of
P. polyphylla
var.
yunnanensis
rhizospheric environment.
Result
2
The inoculation of exogenous AM fungi can regulate the spore densities and infection rate of
P. polyphylla
var.
yunnanensis
rhizosphere AM to improve the root activity, the exogenous AM fungi can also regulate the nutrient contents in the rhizosphere soil,increase the contents of total glomalin and easily extracted glomalin,increase the abilities of
P. polyphylla
var.
yunnanensis
to absorb the available N,P and K,and increase the enzyme activities in the rhizosphere soil, improve the microbial community structure, and improve the rhizospheric environment of
P. polyphylla
var.
yunnanensis
by increasing the bacteria/fungi and bacteria/actinomycetes quantity ratios and reducing the fungi/actinomycetes quantity ratio.
Conclusion
2
Different AM fungal treatment groups had certain effects on the physicochemical properties and microbial community structure of the rhizosphere soil of
P.polyphylla
var.
yunnanensis
,which provided a technical basis for the cultivation of
P. polyphylla
var.
yunnanensis
