耕地土壤质量由土壤肥力状况、土壤安全状况直接构成,并且通过产出农产品的产量与品质间接反映。通州区是北京市重要的农副产品生产基地,其耕地质量的优劣,直接影响着全区种植业的发展水平和北京市农产品的数量与质量。2007-2008年采用取样、实地调查和化验、统计的方法得出:2007年北京市通州区耕地资源总面积为35800hm2,土壤质地以壤土为主,类型为潮土,全区土壤养分土壤有机质、全氮、有效磷、有效钾平均含量分别为15.64g/kg、1.07g/kg、46.15mg/kg和139.32mg/kg,总体处于中等水平。目前耕地质量依然存在许多问题,只有采取综合措施,才能提升耕地质量,保证通州区农业的可持续发展。
The soil quality of arable land is directly constituted by soil fertility status and soil safety status, and is indirectly reflected by the yield and quality of output agricultural products. Tongzhou District is an important production base of agricultural and sideline products in Beijing. The quality of cultivated land has a direct impact on the development level of the planting industry and the quantity and quality of agricultural products in Beijing. From 2007 to 2008, sampling, field survey, laboratory analysis and statistics were used to draw the conclusion that in 2007, the total area of arable land in Tongzhou District of Beijing was 35800hm2. The soil texture was dominated by loamy soil and the type was alluvial soil. Soil organic matter, The average contents of total nitrogen, available phosphorus and available potassium were 15.64g / kg, 1.07g / kg, 46.15mg / kg and 139.32mg / kg, respectively. At present, there are still many problems with the quality of cultivated land. Only by adopting comprehensive measures can we improve the quality of cultivated land and ensure the sustainable development of agriculture in Tongzhou District.
