大蒜、青菜等蔬菜作物对根际微生物的影响
Effects of different cultivated crops of garlic and green vegetable on rhizosphere microorganisms
摘要
Abstract
Garlic and green vegetable are important horticultural crops with different effects on soil microbial communi-ties.In this study,Illumina MiSeq sequencing technology was used to further investigate the effects of different cultivated crops,such as garlic and cabbage,on rhizosphere microorganisms.Results showed that the Q(green vegetable were colo-nized at 0.1 m×0.3 m)treatment increases the diversity and abundence of soil microbial communities,S(garlic were col-onized at 0.1 m×0.3 m)and SC(garlic were colonized at 0.2 m×0.3 m)tended to reduce soil bacteria community diver-sity;The effect of S and SC treatment on bacteria β-diversity is higher than Q;Gemmatimonas and Bacillus were the dominant genera shared by S and SC,and their relative abundance was significantly higher than that of Q and CK.Gem-mat imonas and Saccharibacteria,Ramlibacter bacteria were positively correlated,and Steroidobacter,JTB255 species showed a negative correlation,and had important effects on bacterial community composition.Reducing the garlic plant-ing density can reduce the relative abundance of bacterium,reasonable garlic planting density can play a role in improving bacterial community structure.To further explore the effects of plant root microbial community,regulation and control mechanism and the soil borne disease activity and the relationship between the continuous cropping obstacle has the vital significance.关键词
