通过常规的物理化学实验方法分析了驻马店市高新开发区园林绿地土壤质量现状。结果表明:有机质含量处于中等水平,速效磷含量处于中等偏上水平,土壤速效氮含量较低、部分园林绿地土壤速效氮含量极低,土壤速效钾含量处于中等偏下水平,仅有个别绿地土壤缺乏速效钾;土壤以中壤土、重壤土和轻黏土较多,土壤质地较好;然而土壤紧实度偏高(平均为49.13 kg.cm-2)、土壤鲜土含水量偏低(平均为9.2%),故驻马店市高新开发区园林绿地土壤质量处于中等水平。
Through routine physical and chemical experiments, the status quo of the soil quality in the high-tech development zone of Zhumadian City was analyzed. The results showed that the content of organic matter was moderate, the content of available phosphorus was above mid level, the content of available nitrogen in soil was low, the content of available nitrogen in garden green was extremely low, and the content of available potassium in soil was at the lower middle level. Lack of available potassium. The soil is rich in medium loam, heavy loam and light clay, while the soil texture is good. However, soil compaction is high (49.13 kg.cm-2 on average) and soil fresh water content is low (average, 9.2%). Therefore, the soil quality of the highland development zone of Zhumadian City is at medium level.
