摘要: 该研究以连续种植温郁金(Curcuma wenyujin Y. H. Chen et C. Ling)的土壤为研究对象,通过高通量测序技术,研究施用不同肥料对温郁金根际微生物群落结构的影响。结果显示:施用生物有机肥能够改善土壤微生物的α多样性,增加Burkholderia-Caballeronia-Paraburkholderia、不动杆菌属(Acidibacter)等有益菌、功能菌的丰度,降低镰刀菌属(Fusarium)、茎点霉属(Phoma)等病原真菌的丰度。结果表明,生物有机肥可以通过提高土壤有益菌丰度、抑制病原菌富集、改善土壤微生物群落结构,为植物生长提供有利条件,从而减缓连作障碍的发生。

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
