| 摘 要： | 混农林业作为集约型土地利用和经营方式之一,运用于石漠化地区有利于土壤生物多样性的修复。2019年7月,对贵州省毕节市撒拉溪镇龙场村的玫瑰+大豆、玫瑰+苹果+大豆和玫瑰+玉米3种混农林模式样地中的土壤螨类进行了调查,以玫瑰单作为对照,共捕获土壤螨类1 524头,隶属3目41科64属,以盖头甲螨属(Tectocepheus)和派伦螨属(Parholaspulus)为优势属。其中,玫瑰+玉米样地中具有较丰富的螨类属数,而玫瑰样地中具有较高的个体数量。土壤螨类在4种模式的样地中均呈明显的表聚性。多样性指数和丰富度指数在玫瑰+大豆和玫瑰+玉米样地上较高。4种模式下土壤螨类的群落相似性较低,表现为中等不相似。3种混农林模式样地中捕食性革螨均为r选择型,而玫瑰样地中捕食性革螨为K选择型。甲螨群落结构在玫瑰样地上为P型,在玫瑰+大豆样地上为O型,在其余样地上为G型。总的来说,实施玫瑰混农林治理模式可使土壤螨类数量和多样性增加,以玫瑰为主,与苹果、大豆或玉米混合种植的模式有利于提高土壤螨类多样性,其中,玫瑰+大豆的模式效果较好。 |

| 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], 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 results 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 O 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. |
