Sensitivity Analysis of Soil Bacterial Community in the Tea Garden of Zheng'an County,Guizhou Province
In this study,soil and tea tree samples from two tea gardens in Zheng'an County were examined to investigate the reasons affecting the elemental content of tea.The 16S rRNA gene high-throughput sequencing technology was utilized to analyze the structure of soil bacterial community in the tea plantations,and combined with the physical and chemical properties of the soil to investigate the main environmental factors affecting the soil bacterial community in the tea plantations.The results were as follows:1.SO42-was the main factor affecting the soil bacterial community in the tea plantation.Redundancy analysis of soil bacterial commu-nity structure and SO42-content in tea plantations showed that SO42--had a significant effect on the composi-tion of soil bacterial communities in tea plantations(p＜0.05).2.Heavy metal content within tea leaves was in-fluenced by bacterial taxa.Young tea leaves were more susceptible to soil bacteria,Pseudomonas spp,Ther-moacidophilus spp,Subgroup_2,Rowan Island Bacillus spp(Chujaibacter)and Bacillus spp.had a significant effect on the heavy metal content of young leaves.It provides a new judgment basis for tea quality testing and a new research idea to reduce the content of heavy metal elements in tea leaves by adjusting the structure of soil bacterial community in tea plantations through SO42-.
