为了对齐齐哈尔市主城区绿地土壤质量进行评价,为城市绿地土壤管理提供参考,试验选取6种类型的绿地分别采样,采用多种物理和化学方法,测定了齐齐哈尔市主城区绿地土壤的理化性质。结果表明:齐齐哈尔市主城区绿地土壤质量一般,局部地区土壤质量较差,主要表现在土壤容重偏大,孔隙度和自然含水量较小,有机质、全量养分含量偏低;过氧化氢酶活性比较适中,上下层差异不大,不会由于过氧化氢积累产生毒害作用。
In order to evaluate the quality of the greenbelt in the main urban areas of Qiqihar, this study provides a reference for the management of urban greenbelt soils. Six types of greenbelt were selected for sampling and the physical and chemical properties of the greenbelt in the main urban area of Qiqihar were determined by various physical and chemical methods. The results showed that the quality of the greenbelt in the main urban area of Qiqihar was normal and the soil quality was poor in some areas. The main contents were soil bulk density, low porosity and natural water content, low content of organic matter and total nutrients, and catalase activity Moderate, the difference between the upper and lower, not due to the accumulation of hydrogen peroxide poisoning effect.
