北京上庄水稻土的理化性质的初步研究

A Preliminary Study on the Physical-Chemical Property of Paddy Soil in Shangzhuang of Beijing

上庄镇位于北京市海淀区,由于靠近上庄水库,平均海拔50 m,土质及地下水质优良,是京西有名的鱼米之乡.因此,本文旨在以上庄镇水稻田土壤为研究对象,根据水稻田周边的不同环境,选取四个典型区域的水稻田块,分别分析其土壤PH值,有机质含量,土壤N,P,K含量等理化性质及造成其理化性质差别的原因.本研究通过实验,对上庄镇水稻田的土壤理化性质进行了测定,并与我国土壤肥力分级标准进行对比.综合评价结果认为,北京上庄镇水稻田土壤肥力质量良好,适合作为农产品基地.

Shangzhuang town is located in Haidian district of Beijing. The quality of its soil and groundwater is excellent, because it is close to the reservoir and its average altitude is 50 meters-above sea level. It＇ s well known as a land of abundance of western Beijing. Therefore, this paper takes paddy soil of Shangzhuang as the research object. According to the different environment around the paddy fields, the study selected four typical regions of the paddy fields to analysis the physicochemical properties of soil, for example, pH value, organic matter content, N, P, K content and so on. The study also analyzed the cause of the physicochemical properties in different soils. The physicochemical properties of paddy soil in Shangzhuang of Beijing are measured in experiment in accordarce with the soil fertility classification standard in our country. The comprehensive evaluation results indicate that Beijing Shangzhuang town paddy soil fertility is in good quality. Therefore, Beijing Shangzhuang town is suitable as an agricultural products base.
