不同微生物对高羊茅生长调节特性的影响
Different Microorganisms on Growth Regulation Characteristics of Festuca arundinacea
摘要
Abstract
Microbial communities have important effects on plant growth and development,however,the effects of different microbial dominant communities on root structure and soil microbial community diversity have not been fully investigated.Our experiment explores the effects of four different microbial dominant communities on the growth of Festuca arundinacea,root system structure,rhizosphere soil microbial diversity and screens for excellent strains that promote the growth of Festuca arundinacea.A pot experiment was conducted to study the effects of Bacillus subtilis(K),Bacillus amyloliquefaciens(JD),Aspergillus niger(H),and Trichoderma harzianum(HC)on the growth of Festuca arundinacea,root system configuration and anatomy,soil microbial community structure.The results showed that under microbial-Festuca arundinacea interactions system,Trichoderma harzianum and Bacillus subtilis not only effectively promoted the growth of Festuca arundinacea but also significantly enhanced its roots ability to absorb and transport water and nutrients.In addition,the compositions of different microbial communities vary significantly,with the main dominant bacterial groups being beneficial for improving the micro-ecological environment of poor soils.In the comprehensive analysis,bacillus subtilis and trichoderma harzianum had a strong promotion effect on Festuca arundinacea,which provides a reference for the application of Festuca arundinacea in production and ecological construction and the understanding of microbial-plant interactions.关键词
