- Abstract
As one of the intensive land use and management methods, agroforestry is beneficial to the restoration of soil biodiversity in rocky desertification areas. In July 2019, a total of 1 524 soil mites belonging to 3 orders, 41 families, 64 genera were captured from three kinds of agroforestry modes, namely, rose (Rosa rugosa Thunb) + soybean [ Glycin max (Linn) Merr J-rose +apple ( Malus pumila Mill) + soybean, rose +corn (Zea mays Linn), with single cropping of rose mode as the control, in Longchang Village, Salaxi Town, Bijie City, Guizhou Province. The relsults showed that Tectocepheus and Parholaspulus were the dominant genus of soil mites in this area. Among all the four modes, rose+ corn had a richer quantity of mite genera, while rose had a higher individual quantity. Soil mites were manifested as surface aggregation under four models. Rose+ soybean and rose+ corn had a higher diversity index and richness index. The similarity of soil mite communities among four models was relatively low, which belonged to medium unsimilarity. Predatory mites ( Gamasina) were r-selected under three agroforestry modes, while it was K-selected under single cropping of rose mode. The structure of Oribatid mite community was P type under rose mode, and was 0 type under rose +soybean mode, and was G type under the other modes. In general, the implementation of rose-based agroforestry management increased the quantity and diversity of soil mites. Rose-based agroforestry with apple, soybean or corn was beneficial for the improvement of soil mite diversity, and the rose + soybean mode was more effective.
