Abstract:

In this study, the soil of continuous planting of Curcuma wenyujin Y. H. Chen et C. Ling was used as the research object. By using the high-throughput sequencing technology, the impact of various fertilizers on the rhizosphere microbial community structure of Curcuma wenyujin was explored. The results showed that the application of bio-organic fertilizer could improve the α-diversity of soil microorganisms, increase the abundance of beneficial and functional bacteria such as Burkholderia-Caballeronia-Paraburkholderia and Acidibacter, yet decrease the abundance of pathogenic fungi such as Fusarium and Phoma. The results indicated that the application of bio-organic fertilizer could improve the soil microbial community structure by increasing the abundance of probiotics and inhibiting the proliferation of pathogenic bacteria, thereby providing favorable conditions for plant growth, and ultimately aiding to mitigate the challenges associated with continuous cropping.

Key words: Curcuma wenyujin, bio-organic fertilizer, rhizosphere microorganism, high-throughput sequencing
