整合微生物组菌剂对番茄植株生长及根际细菌群落多样性的影响
Effects of Integrated Microbiome Agent on Tomato Plant Growth and Rhizosphere Bacterial Community Diversity
摘要
Abstract
To study the effect of integrated microbiome agent(IMA)on tomato plant growth,using greenhouse substrate cultivation method,3 treatments were set including old substrate(TA),old substrate+10%IMA and new substrate(TC).The growth of tomato and rhizosphere bacterial community diversity under different treatments were determined.The results showed that,compared with TA treatment,TB treatment significantly promoted the growth of tomato plant,but had little effect on the nutritional status of old substrate.Therefore,IMA should be used in conjunction with other(biological)organic fertilizers to improve the microbial population structure and nutritional composition of the substrate.A total of 40 phyla,121 classes,291 orders,438 families and 748 genera were detected by 16S rRNA high-throughput sequencing technology,and Proteobacteria was the most abundant phyla with relative abundance 35.24%-38.25%,Actinomycetes(13.20%～20.60%)followed.TB treatment significantly increased the relative abundance of Actinomycetes,and decreased the abundance of Firmicutes,but had little effect on the diversity and richness of bacterial community in substrate.Actinomyces and Proteobacteria were positively correlated with total potassium,total nitrogen and organic matter contents,but negatively correlated with total phosphorus content and pH.Firmicutes,Chloromyces and Acidobacteria were positively correlated with the total phosphorus content and pH,and negatively correlated with the contents of total potassium,total nitrogen and organic matter.Among the substrate physical and chemical factors,the pH,total nitrogen,total phosphorus and total potassium contents had significant effects on the bacterial community,and total nitrogen was the most important environmental factor.Therefore,during the repeated use of tomato substrate,the application of IMA should be combined with the appropriate nitrogen fertilizer,which should beneficial to increase the nutrient contents of substrate and improve the substrate microbial community structure,so as to ensure the good development of tomato substrate ecosystem.关键词
