摘要:

为研究火山岩地区土壤中营养元素的浓度水平及其空间分布特征,选取黑龙江五大连池卧虎山农场为研究区,系统采集41件表层土壤样品,测试分析氮、磷、钾等植物营养元素以及有机质、pH值等15项指标,绘制元素地球化学图,掌握了该区营养元素含量的空间分布特征。根据相关标准,评价土壤中营养元素的丰缺水平。结果表明:(1)研究区为酸性土壤,土壤营养元素含量总体丰足,只有硼含量稍缺或缺乏;(2)土壤营养元素具有明显的空间分布规律,以卧虎山北部含量较高、跃进水库附近较低为特征;(3)研究区为温暖湿润条件下的中等化学风化,伴随着成土作用营养元素持续从岩石释放到土壤中,且有机质对土壤营养元素具有良好的吸附性。本研究为当地农业生产中养分的合理利用和农业种植规划提供了第一手数据资料。

Abstract:

In order to investigate the concentration and spatial distribution, as well as geochemical characteristics of nutrition elements in the volcanic rock area of the Wohushan farm in Wudalianchi, Heilongjiang pro-vince, a total of 41 topsoil samples were collected and the concentration of essential nutrient elements and physic-chemical indexes, such as nitrogen, phosphorus, potassium,organic matter as well as pH were measured. The abundance and deficiency level of nutrient elements in soils were evaluated according to the relevant standards. The results show that: (1) the type of soil in the study area belongs to acidic soil, and the soil nutrient elements of the study area are of high quality, except that boron element content is slightly deficient or lacking; (2) the spatial distribution of soil nutrient elements, is characterized by a higher value in the north of the Wohushan farm and a lower level near the Yuejin reservoir; (3) the soil within the study area were deve-loped under the moderate chemical weathering and warm humid conditions. The nutrients were released continuously into the soils in the process of soil forming, and organic matters had good adsorption capacity for soil nutrients. This study provides first-hand data for the rational use of nutrients in the local agricultural production and the planning of agricultural planting.
