| 为探究低镉水稻品种对稻田节肢动物群落的影响，进一步评价低镉水稻安全性，于2022-2023连续两年在湖南省株洲市攸县通过扫网法和盆拍法调查了低镉稻田和常规稻田节肢动物群落动态规律，并分析节肢动物群落丰富度、群落优势度指数和香农指数等群落特征参数。通过调查，共获得节肢动物个体7 032头，分属10目46科65种，大多数为植食性害虫与捕食性天敌，寄生性天敌少。结果表明，低镉稻田的节肢动物物种组成、物种丰富度、香农指数、均匀度指数和优势集中度及其时间动态与常规稻田基本一致，采集的节肢动物优势科与优势种也基本相同，说明低镉水稻品种对稻田节肢动物群落基本无负面的影响。 |

| In order to further evaluate the safety of low-cadmium rice by exploring the effects of low-cadmium rice varieties on arthropod communities in paddy fields, we investigated the dynamics of arthropod communities in low-cadmium paddy fields and conventional paddy fields in Youxian County, Zhuzhou City, Hunan Province for two consecutive years from 2022 to 2023 by sweep net method and basin-beating method, and analyzed the community characteristic parameters such as arthropod community richness, community dominance index and Shannon index. Through investigation, a total of 7 032 individuals of arthropods were obtained, belonging to 10 orders, 46 families and 65 species. Most of them were phytophagous pests and predatory natural enemies, and there were few parasitic natural enemies and neutral insects. The results showed that the species composition, species richness, Shannon index, evenness index, dominant concentration and time dynamics of arthropods in low-cadmium paddy fields were basically the same as those in conventional paddy fields. The dominant families and dominant species of arthropods were also basically the same, indicating that low-cadmium rice varieties had no negative effect on the arthropod community in paddy fields. |
