- Abstract:
-
In order to understand the soil fungal structure and diversity characteristics of Medicago sativa in Yellow River diversion irrigation area, change mechanism of planting years were studied, and the scientific basis for artificial grassland management was provided. The 18SrDNA high—throughput sequencing method was used to analyze the community composition and abundance, Alpha diversity, Beta diversity and the structure of the bacterial community of Medicago sativa(1~6 a)planted in the Yellow River irrigation area for different years. The composition of the fungal community was correlated with the soil physical and chemical factors relevant analysis. The results showed that the dominant genere of fungi detected were Chaetomium, Fusarium, Gibberella, Lectera, Monograph Ella at the genus level. The results of diversity analysis showed that the abundance and diversity of soil fungal flora reached the highest when the planting time was 5 years, and the similarity of species diversity composition reached the highest when the planting time was 2 years and 3 years. With the change of planting years, the changes of soil fungal communities showed a trend of first decreasing and then increasing, and had a significant correlation with soil physical and chemical properties. The pH value, available nitrogen, and organic carbon are the main factors affecting the composition of Medicago sativa fungal community.
