摘要:
以猕猴桃开花坐果期为观测窗口,对比分析生草覆盖(SC)、园艺地布覆盖(LS)与清耕(CK)对果园土壤微生物群落结构、酶活性及养分含量的影响。结果显示:SC和LS处理显著优化了土壤微生物多样性及功能类群。真菌OTU数目在SC(504)和LS(676)中较CK(448)分别增加12.5%和50.89%,且LS独有真菌OTU占比达51.63%。α多样性分析显示,SC和LS处理显著提高真菌群落丰富度(ACE、Chao1指数较CK提升23.53%~68.22%)和多样性(Shannon指数提高11.14%~11.94%),细菌群落的分布均匀度亦显著改善。群落结构上,SC和LS处理显著提升子囊菌门(相对丰度达55.32%和47.86%)、酸杆菌门等有益菌群丰度,同时降低油壶菌门、生赤壳属等潜在病原菌比例。土壤养分方面,SC和LS处理显著提高有机质(增幅31.38%、65.76%)、全氮(21.79%、15.48%)及速效钾(6826%、34.15%)含量,LS增强脲酶活性(LS较CK提升63.53%),SC提高蔗糖酶(21.97%)及纤维素酶活性(2346%)。综上,果园生草(SC)与地布覆盖(LS)通过调控土壤微生物群落结构与功能,差异化驱动养分循环。综合土壤养分提升、酶活性优化及微生物功能多样性,SC处理在速效养分活化、碳周转及土壤健康调控方面更具优势,在开花期结合刈割深翻,可成为改善猕猴桃果园土壤生态功能的更优覆盖模式。
