Fenlong-Ridging Promotes Microbial Activity in Sugarcane: A Soil and Root Metabarcoding Survey

Fenlong-ridging (FL) is a recently proposed conservation tillage technology which has dramatic differences to traditional ones. Previous studies have demonstrated in many crops that FL yield-increasing effects without additional inputs. However, little known about the role microbes play mediating growth-promoting of FL, restricts its further application and improvement. Here, we characterized variation soil root microbial diversity sugarcane (GT44) under turn-over plough (CK) by conducting 16S rRNA ITS metabarcoding surveys. We also measured several phenotypic traits determine yields analyzed chemical properties soil. found that: (i) plant height (PH) total biomass weight (TW) plants were 9.1% 21.7% greater than those CK, indicating\increased yield operation; (ii) contents organic matter, nitrogen, available phosphorus, potassium lower indicates utilization nutrients was soil; (iii) promoted activity endophytic roots, these diverse taxa might an effect on properties; (iv) Sphingomonas, Rhizobium, Paraburkholderia Talaromyces, Didymella, Fusarium top three most abundant genera bacteria fungi, respectively, samples. In addition, strains from Rhizobium Talaromyces isolated verify results survey. Overall, our study provides new insights into FL. These findings could be used improve applications this novel technology.
