Effect of Arbuscular Mycorrhizal Fungi Inoculation on Physical and Chemical Properties of Rhizosphere Soil of Paris polyphylla var. yunnanensis
at different periods,the changes of mineral nutrients in rhizosphere soil and the correlation among the factors under different arbuscular mycorrhizal (AM) fungi conditions.
Method
2
28 kinds of AM fungi were inoculated into the seedlings of
P. polyphylla
var.
yunnanensis
by single factor pot experiment. The samples were collected in August (fruit ripening period) and November (senescence period) to analyze the infection rate and the physical and chemical properties of rhizosphere soil.
Result
2
The mycorrhizal infection rate of each treatment group was 75%-100% in the fruit ripening period and senescence period. The contents of easily extracted
glomalin
and total
glomalin
in rhizosphere soil increased to different degrees in these two periods as compared with CK group, the pH of rhizosphere soil in the two treatment groups showed an increasing trend, the content of organic matter in rhizosphere soil decreased significantly in the fruit ripening period in all the treatment groups,and the organic matter in rhizosphere soil in the senescence period showed no significant differences. The total N and K contents in rhizosphere soil decreased in both periods, and the other physical and chemical properties of rhizosphere soil increased or decreased without significant change regularity. Correlation analysis showed that the infection rate was correlated with the physical and chemical properties of rhizosphere soil to a certain degree.
Conclusion
2
Inoculation of AM fungi can affect the physical and chemical properties of rhizosphere soil of
P. polyphylla
var.
yunnanensis
to some extent,and provide reference value for the application of AM fungi in the cultivation of traditional Chinese medicine.
