Abstract: In order to investigate the effects of different fertilization methods on the community structure of Collembola in black soil farmland, and promote the research on Collembola diversity and black soil protection in black soil farmland, a long-term fertilizer positioning experiment was carried out in black soil farmland of Harbin City, Heilongjiang Province from 2012 to 2021. Four different fertilization treatments of organic fertilizer (OM), semi-organic fertilizer (OM+NPK), inorganic fertilizer (NPK) and no fertilizer (CK) were set up respectively, and the community structure of the order was investigated under different fertilization treatments. The results showed that a total of 2 045 Collembola were obtained, belonging to 9 families. Under different fertilization treatments, the number of Collembola individuals was in the order of OM+NPK(537)> OM(536)> CK(523)>NPK(449). The number of individuals and groups of Collembola in the OM and OM+NPK treatment increased significantly, among which Isotomidae increased the most. However, the number of individuals and groups of Collembola decreased in the NPK treatment group, and the increase in Isotomidae was the smallest compared with the other fertilization treatments. Compared with the CK treatment, the diversity index and richness index of Collembola were decreased in the three different fertilization treatments, and the diversity index of the OM+NPK treatment was the lowest. Redundancy analysis(RDA) showed that different environmental factors mainly affected the dominant groups and common groups of Collembola, which were significantly correlated with soil organic matter content and total potassium content. The indicator species analysis showed that Cyphoderidae was the indicator species for OM+NPK treatment, Neanuridae was the indicator species for NPK treatment, Hypogastruridae, Sminthuridae and Entomobryidae were the indicator species for CK treatment.
