摘要
文章以北仑区土壤为研究对象,对城市和周边郊区进行了详细调查,通过采集表层土壤样品中的养分指标进行测试,结果表明研究区耕地表层土壤养分总体以较丰富和中等为主,分别占耕地面积的46.49%、27.16%;丰富级占比18.19%。同时发现区内分布有大面积的富硒土壤,共计0.45×10^(4) hm^(2),依托北仑区传统优势农产品,对富硒农产品的开发利用给出了建议。
In this paper,taking the soil of Beilun District as the research object,a detailed investigation was carried out in the city and surrounding suburbs,and the nutrient indicators in the surface soil samples were collected and tested.It accounts for 46.49%and 27.16%of the cultivated land area;the rich level accounts for 18.19%.At the same time,it is found that there is a large area of selenium-enriched soil in the area,with a total of 0.45×10^(4) hm^(2).Relying on the traditional advantageous agricultural products in Beilun District,suggestions are given for the development and utilization of selenium-enriched agricultural products.
