深圳围岭公园土壤资源及其合理开发利用
Soil Resources and Their Reasonable Utilization of Weiling Park in Shenzhen City,Guangdong Province
【摘要】 对深圳围岭公园土壤的成土条件、土壤类型、理化性质进行了分析,对N、P等土壤养分含量水平进行了评价,并提出了土壤利用的建议。围岭土壤主要为砂岩赤红壤,土壤石砾含量较高,土壤质地为中壤土或重壤土;土壤呈酸性至强酸性反应;有机质平均含量为19 9g·kg-1,全氮含量为0 59g·kg-1,速效氮、磷含量分别为74 92mg·kg-1和0 88mg·kg-1,均属于中下水平。
【Abstract】 In this paper,the types of the soils in Weiling Park and their development conditions was analyzed the basic properties of the soil samples, evaluated the soil fertility, especially N and P contents etc\^, basing on the survey and physicochemical analysis,authous put forward some proposals about soil conservation and utilization. Results showed that the major soil type in Weiling Park of Shenzhen is lateritic red earth derived from sandstone, whose texture is largely gravelly loam. The soil is acidic or strongly acidic. Contents of organic matter, total nitrogen, alkali-soluble nitrogen and available phosphorus are all low or very low, with the mean contents being 19.89 g.kg-1, 0.59 g.kg-1, 74.92 mg.kg-1 and 0.88 mg.kg-1, respectively. As far as the soil conditions are concerned, we suggest that organic compound fertilizer with high phosphorus content be applied, suitable tree species be selected for the plantation reconstruction and multiple-storey forest stands be established in the park.
