| 摘 要： | 【目的】咖啡豆残渣作为农业废弃物具有一定的资源化利用价值，为研究咖啡豆残渣有机肥在雪茄烟叶生产中的应用效果。【方法】以咖啡豆残渣有机肥为主设计3种配方有机肥、作基肥穴施，分析各处理对雪茄烟株生长、植烟土壤肥力及根际土壤真菌群落结构的影响。【结果】（1）3种配方有机肥处理下雪茄烟的株高、叶长和叶宽均有显著提升，其中“菜籽粕+酒糟+咖啡豆残渣”的配方有机肥处理（T2）效果最好。（2）各处理下的土壤有机质、富里酸、全氮、有效磷和速效钾含量较对照均增加。团棵期土壤的有效磷、速效钾、全氮、有机质、胡敏酸和富里酸含量，以及成熟期的土壤速效钾和碱解氮含量都显著影响根际真菌群落结构。（3）3种配方有机肥均可改变雪茄烟根际真菌的优势种群，降低α多样性，且各处理下团棵期α多样性均大于成熟期。T2处理可显著降低根际土壤中明梭孢属和镰刀菌属的相对丰度，显著提高圆酵母属、曲霉属和被孢霉属的相对丰度。LEfSe分析表明，在门水平下处理间差异物种为子囊菌门和被孢霉门；在属水平下处理间差异物种为镰刀菌属、曲霉属、明梭孢属和被孢霉属。【结论】咖啡豆残渣有机肥可提高雪茄植烟土壤肥力、影响根际土壤真菌群落和促进雪茄生长。本...

| Abstract: | Purpose Coffee bean residue as agricultural waste has certain resource utilization value, but the application effect of coffee bean residual organic fertilizers in the production of cigar leaves remains to be studied. Methods Based on the organic fertilizers of coffee bean residues, three formulas of organic fertilizers were designed and applied as base fertilizers. The effects of each treatment on cigar plant growth, tobacco planting soil fertility and rhizosphere soil fungal community structure were analyzed. Results (1) The plant height, leaf length and leaf width of cigars were significantly increased under the three organic fertilizer treatments, and the formulated organic fertilizer treatment (T2) of "rapeseed meal + distiller's grains + coffee bean residue" exhibited the best performance. Under these treatments, the contents of soil organic matter, fulvic acid, total nitrogen, available phosphorus and available potassium were all increased compared with the control. (2) The contents of available phosphorus, available potassium, total nitrogen, organic matter, humic acid and fulvic acid in the soil at the Cluster stage, as well as the contents of available potassium and alkali-hydrolyzed nitrogen in the soil at the Harvest stage significantly affected the structure of the rhizosphere fungal community. (3) All the three treatments could change the dominant population of fungi in cigar rhizosphere fungi reduce the α-diversity, and the α-diversity at the Cluster stage was greater than that at the Harvest stage under each treatment. T2 treatment significantly decreased the relative abundances of Monographella and Fusarium in the rhizosphere soil, and significantly increased the relative abundances of Torula, Aspergillus and Mortierella. LEfSe analysis showed that the different species between treatments were Ascomycota and Mortierella at the phylum level, and the different species among treatments were Fusarium, Aspergillus, Monographella and Mortierella at the genus level. Conclusion Coffee bean residue organic fertilizers can improve the soil fertility of cigar tobacco planting, affect the fungal community in rhizosphere soil, and promote the growth of cigar plants. This study provides a reference for the resource utilization of coffee bean residue organic fertilizers in cigar production. |
