| 摘 要： | 为探讨玉米秸秆生物质炭不同施用量对土壤节肢动物群落结构的影响，于2019年5—10月分别对0、5、10、20和50 t/hm2生物质炭处理下的贵州石灰性旱地农田土壤小型土壤节肢动物群落进行调查，并探讨土壤节肢动物群落与土壤温度、湿度、pH、电导率和有机碳等环境因子的关系。本研究共捕获土壤节肢动物14 133头，隶属于6纲21类群。研究表明：适量生物质炭添加（10 t/hm2）有助于提高土壤节肢动物个体数和类群数，高量施用（50 t/hm2）则不利于土壤节肢动物生存；典范对应分析结果显示，生物质炭施用导致环境因子的变化显著影响了土壤节肢动物群落结构（共解释了24.81%的物种变异，P<0.01），其中温度的影响最大，单独解释了物种变异的16.1%。总体上，施用生物质炭影响土壤微环境，进而影响土壤节肢动物群落组成和多样性，施用适量生物质炭（10 t/hm2）有益于农田土壤节肢动物的生存，但这一结论还需要在其他土壤类型和生物质炭中进行验证。

| Abstract: | In order to explore the influence of biochar application on the community structure of soil arthropods and their association with soil parameters, including soil temperature, humidity, pH, electrical conductivity and soil organic carbon, biochar produced from maize straw was applied at the rates of 0, 5, 10, 20 and 50 t/hm2 in an alkaline soil farmland in Guizhou. A total number of 14 133 individuals of soil arthropods were captured, belonging to 6 classes, 21 groups. An appropriate amount of biochar application, e.g. 10 t/hm2, increased the individuals and group numbers of soil arthropods. Negative effect of biochar on soil arthropods was observed with excessive biochar application, e.g. 50 t/hm2. Canonical correspondence analysis showed that soil arthropods community was significantly correlated with the measured environmental factors (adjusted R2=24.81%, P<0.01), and most affected by soil temperature, which explained 16.1% of the variance. In general, the application of biochar changed soil microenvironment, affecting the community structure of soil arthropods. An appropriate amount of biochar application, e.g. 10 t/hm2 was beneficial to farmland soil arthropods community. Further studies were needed to focus on different types of soils and biochars. |
