摘要: 为进一步明确行间生草对改善果园土壤生态环境的影响,本研究以柑橘园为研究对象,比较不同绿肥管理模式对柑橘园土壤理化特性和细菌群落的影响。结果表明,种植白三叶草后土壤碱解氮、全氮、无机磷、有机质含量分别显著(p<0.05)提高61.09%、52.85%、43.08%、60.72%;种植苕子后土壤碱解氮、有机质含量分别显著提高15.88%、55.85%;种植鼠茅后土壤有机质含量显著提升31.70%;在大棚内种植鼠茅后土壤碱解氮、全氮、有机质含量分别显著提升48.52%、18.03%、60.87%。对土壤细菌16S rRNA基因的V3~V4区进行高通量测序和分析,在Silva数据库上对应注释至43门620属微生物。种植白三叶草和在大棚内种植鼠茅后,鉴定到的土壤运算分类单元(OTU)数量分别显著增加17.17%、23.98%,且土壤微生物的α多样性增加。种植白三叶草、苕子、黑麦草、鼠茅和大棚内种植鼠茅前后,土壤细菌群落在属水平上分别有56、26、20、15、47个属的相对丰度差异显著。综上所述,在柑橘园种植白三叶草对提高土壤肥力和微生物多样性效果最佳,辅以大棚设施对生草管理具有明显的加成作用。

Abstract:

To further clarify the effects of inter-row sod culture on improving the soil ecological environment of orchards, this study took citrus orchards as the research object and compared the impacts of different green manure management modes on soil physicochemical properties and bacterial communities. The results showed that the contents of alkali-hydrolyzable nitrogen, total nitrogen, inorganic phosphorus and soil organic matter were significantly (p<0.05) increased by 61.09%, 52.85%, 43.08% and 60.72%, respectively, after planting Trifolium repens. For Vicia dasycarpa cultivation, the contents of soil alkali-hydrolyzable nitrogen and organic matter rose significantly by 15.88% and 55.85%, respectively. Planting Vulpia myuros significantly increased soil organic matter content by 31.70%. When Vulpia myuros was planted in greenhouse, the contents of soil alkali-hydrolyzable nitrogen, total nitrogen and organic matter were significantly elevated by 48.52%, 18.03% and 60.87%, respectively. High-throughput sequencing was performed on the V3-V4 region of the 16S rRNA gene of soil bacteria, and sequence annotation against the Silva database identified a total of 43 phyla and 620 genera of microorganisms. The number of soil operational taxonomic units (OTUs) increased significantly by 17.17% and 23.98% in the treatments with Trifolium repens and Vulpia myuros cultivated in greenhouse, respectively, accompanied by an increase in soil microbial α-diversity. At the genus level, there were significant differences in the relative abundances of 56, 26, 20, 15 and 47 bacterial genera with the plantation of Trifolium repens, Vicia dasycarpa, Lolium perenne, Vulpia myuros, and Vulpia myuros in greenhouse, respectively. In conclusion, planting Trifolium repens in citrus orchards achieves the optimal effects in improving soil fertility and microbial diversity, and the combination with greenhouse facilities can further enhance the performance of sod culture management.
