摘要 明确光伏板下种植的滇黄精上节肢动物群落组成结构及多样性,为光伏板下滇黄精害虫的综合治理及光伏农业发展提供技术支撑。2023年,采用目测调查和蓝板诱集调查相结合的方法,对光伏板下和露天种植的滇黄精上节肢动物种类和数量进行调查,采用群落多样性指数对节肢动物群落多样性进行评估,并对主要害虫的种群动态进行分析。结果表明,光伏板下种植的滇黄精上节肢动物有2纲10目25科27属27种,露天种植滇黄精上有2纲10目28科30属30种。整个调查期间,随着时间的推移,2种种植模式滇黄精节肢动物群落的多样性指数和均匀度指数整体上表现为光伏板下种植高于露天种植,且均呈“降低-升高”变化,优势度指数呈“上升-降低”变化。光伏板下种植的滇黄精上节肢动物群落丰富度指数呈“升高-降低-升高”的动态变化,而露天种植处理丰富度指数呈“升高-降低-保持”的变化。2种种植模式下滇黄精节肢动物群落相似度较高,达0.84,优势种均为神泽氏叶螨(Tetranychus kanzawai),其种群数量呈单峰型变化,但光伏板下的神泽氏叶螨种群数量显著低于露天种植,光伏板下5月达数量高峰(6.77头/株),而露天种植于7月达数量高峰(14.75头/株)。综上,光伏板下种植的滇黄精上节肢动物群落多样性高于露天种植,且有利于控制优势害虫神泽氏叶螨的种群数量。 To clarify the structure and diversity of the arthropod community on Polygonatum kiugiauum planted under photovoltaic panels,and provide technical support for the integrated pest management on P.kiugiauum under photovoltaic panels and the development of photovoltaic agriculture,a systematic investigation on the species was conducted using the visual survey and blue sticky card trapping in P.kiugiauum planting areas under photovoltaic panels and open‑field planting in 2023,the community diversity of arthropods was evaluated using the community diversity index and population dynamics of major pests was analyzed.The results showed that there were 27 species of arthropods belonged to 27 genera,25 families,10 orders and 2 classes on P.kiugiauum under the photovoltaic panels.Additionally,there were 30 species of arthropods in 30 genera,28 families,10 orders and 2 classes under open‑field planting of P.kiugiauum.During the whole investigation period,the diversity index and evenness index of arthropod community on P.kiugiauum planted under photovoltaic panels were higher than those planted in the open‑field and followed a dynamics of decrease‑increase,and the dominance index followed an increase‑decrease dynamics.The richness index of arthropod community on P.kiugiauum under photovoltaic planting followed a dynamics of increase‑decrease‑increase,while open‑field planting followed a dynamics of increase‑decrease‑constancy.The similarity of arthropod communities on P.kiugiauum was high with a value of 0.84 under the two planting modes.The dominant species of arthropods was Tetranychus kanzawai,whose population showed a single‑peak pattern.However,the population under the photovoltaic panels was significantly lower than that in open‑field planting,with a peak of 6.77 in May under the photovoltaic panels,and a peak of 14.75 in July under open‑field planting,respectively.In conclusion,the diversity of arthropod communities on P.kiugiauum planted under photovoltaic panels was higher than that under open‑field planting,and it was favourable for the control of the dominant pest T.kanzawai.
