贵州省安顺市耕地表层土壤养分元素分布特征

本文依据安顺市表层土壤样品地球化学调查数据,从有机质、碱解氮、速效磷及速效钾四个方面分析,表明安顺市近90%以上的耕地表层土壤有机质、碱解氮及速效钾含量均处于中等以上水平,速效磷的含量有90%以上的耕地处在中等以下水平。依据本次的研究结果,可以为安顺市农业科学施肥提供更好的指导,以便通过人为的手段来调节土壤养分含量,为农作物提供更好的生长环境,从而达到增产、增质、增效的目的,更好的服务于农村、农业、农民。

Distribution Characteristics of Nutrient Elements in Surface Soil of Cultivated Land in Anshun City, Guizhou Province

In this paper, based on the test data of surface soil samples in Anshun city, it makes a brief analysis from four aspects of organic matter, alkali hydrolyzed nitrogen, available phosphorus and available potassium. The results show that more than 90% of the cultivated land in Anshun city has the content of organic matter, alkali hydrolyzed nitrogen and available potassium above the middle level, and more than 90% of the cultivated land has the content of available phosphorus below the middle level. With the results of this study, it can provide better guidance for agricultural fertilization in Anshun city, so as to regulate the content of soil nutrient elements through human means, provide better growth environment for crops, and better serve rural areas, agriculture and farmers.
