摘要
以辣椒品种鸡爪×吉林为材料,采用穴施方法,研究微生物菌剂对连作地块辣椒生长和微生物群落的影响。结果表明,微生物菌剂在一定程度上促进了辣椒生长,株高、茎粗、果长、果宽和产量等指标均显著高于不施用微生物菌剂的对照,其中产量增加幅度最大,较对照显著提高了14.76%。施用微生物菌剂提高了土壤中真菌和细菌相对物种数量和OTU数量;通过KEGG代谢途径分析,发现代谢通道是差异功能最显著富集的通路,相对丰度近80%。综上,微生物菌剂能够改善土壤真菌和细菌群落结构,促进辣椒植株生长,提高辣椒产量。
Using the chili variety Chicken Claw x Jilin as the material,the effect of microbial agents on the growth and microbial community of chili pepper in continuous cropping plots was studied through hole application method.The results indicate that the microbial agent(SW)promotes the growth of pepper to a certain extent.The plant height,stem diameter,fruit length,fruit width and yield of the plant are significantly higher than those of the control(CK).Notably,the yield is the largest,with an increase of 14.76%compared to the control.The application of microbial agent increases the relative species number and OTU number of fungi and bacteria in the soil.Through KEGG metabolic pathway analysis,it is found that metabolism is the pathway with the most significant enrichment of differential functions,with relative abundance of nearly 80%.Comprehensive analysis shows that microbial agent can improve the community structure of soil fungi and bacteria,promote the growth of pepper plant,and increase pepper yield.
