摘　　要：为优化大棚连作青椒的栽培模式,选取连续种植3 a(6茬)的大棚青椒作为研究对象,通过田间试验,对比分析了6种不同的种植模式对青椒产量、品质及土壤细菌多样性的影响,并初步探讨了这三者之间的相关性。研究结果显示,在施基肥+翻耕+原点定植(T4)的种植模式下,青椒的单株鲜质量、单株干质量及产量均达到最高,分别为337.53 g、78.77 g、3 506.65 kg·667 m^(-2),相较于施基肥+翻耕+非原点定植(对照组T3)分别提高了22.71%、20.24%和28.91%;其次是不施基肥+免耕+原点定植模式(T6),其他处理组的鲜质量、干质量及产量均低于对照组5.06%~27.26%、13.10%~21.45%和7.55%~19.33%。在土壤细菌的OTUs、ACE、Shannon指数方面,T6与T4处理组普遍高于其他处理组,相较于对照组,增幅为1.14%~4.11%。在品质方面,不施基肥+免耕+非原点定植模式(T5)下的青椒品质最优。不同种植模式下优势菌群基本相似,主要包括变形菌门、放线菌门、厚壁菌门、拟杆菌门、酸杆菌门。通过Pearson相关性分析表明,Alpha多样性指数与辣椒产量呈正相关,与品质指标呈负相关。综合考量多种因素,施用基肥、翻耕及原点定植(T4)或不施用基肥、免耕及原点定植(T6)是推荐的两种种植模式。In order to optimize the cultivation model for continuous cropping of greenhouse green pepper,a green pepper greenhouse with 3 years of continuous planting(6 stubble)was selected as the research object.Through field experiments,the influence of 6 different planting modes on the yield,quality and soil bacterial diversity of green pepper was relatively analyzed,and the correlation between these three factors was preliminarily explored.The results showed that under the planting mode of applying base fertilizer+tillage+origin planting(T4),the total fresh mass,total dry mass,and yield of green pepper reached the highest,which were 337.53 g,78.77 g and 3506.65 kg·667 m^(-2),respectively.Compared to the control group(base fertilizer+tillage+non-origin planting)(control T3),these increased by 22.71%,20.24%and 28.91%,respectively.Secondly by the no-base fertilizer+no-tillage+origin colonization mode(T6),the fresh mass,dry mass and yield of other treatment groups were 5.06%-27.26%,13.10%-21.45%and 7.55%-19.33%lower than those of the control group.In terms of OTUs,ACE and Shannon index of soil bacteria,the T6 and T4 treatment groups were gener-ally higher than those of other treatment groups,with an increase of 1.14%to 4.11%compared to the control group.In terms of quality,the quality of green pepper under no base fertilizer+no-tillage+non-origin planting mode(T5)is optimal.The dominant microbial communities were basically similar in different planting patterns,including Proteobacte-ria,Actinobacteria,Firmicutes,Firmicutes,Bacteroidetes,andAciobacterium.Pearson correlation analysis showed thatAlpha diversity index was positively correlated with pepper yield and negatively associated with quality index.Considering vari-ous factors comprehensively,the application of base fertilizer,tillage and origin the application of base fertilizer,tillage and origin planting with or without base fertilizer,no tillage and origin planting are the two recommended planting modes.
