基于对10年来扬州市162个长期定位耕地质量监测点数据分析,研究结果表明:10年来扬州市耕地层土壤养分有机质、有效磷、有效硼含量呈稳定上升趋势,速效钾、有效锌含量呈稳定趋势;耕地质量指数呈稳定上升趋势,2012年比2003年提高了0.57,平均达1.92,属于中等水平;与近几年大力推广测土配方施肥、土壤有机质提升技术有密切关系。10年来稻麦基础地力产量呈明显上升趋势,除了作物品种、栽培方式等更新外,与耕地质量不断提升有着密切关系。
基于對10年來颺州市162箇長期定位耕地質量鑑測點數據分析,研究結果錶明:10年來颺州市耕地層土壤養分有機質、有效燐、有效硼含量呈穩定上升趨勢,速效鉀、有效鋅含量呈穩定趨勢;耕地質量指數呈穩定上升趨勢,2012年比2003年提高瞭0.57,平均達1.92,屬于中等水平;與近幾年大力推廣測土配方施肥、土壤有機質提升技術有密切關繫。10年來稻麥基礎地力產量呈明顯上升趨勢,除瞭作物品種、栽培方式等更新外,與耕地質量不斷提升有著密切關繫。

The data from 162 long-term and located points of monitoring cultivated land quality in Yangzhou city in recent 10 years were analyzed.The results showed that:over the past 10 years, the contents of organic matter, available P and available B in the cultivated land of Yangzhou city revealed a steady rising trend, and the contents of rapidly-available K and available Zn were stable.The index of cultivated land quality increased steadily, and averagely reached 1.92 (an intermediate level) in 2012, being 0.57 higher than that in 2003, which had a close relation with the energetic popularization of soil testing and formulated fertilization, and soil organic matter promoting technique in recent years.During last 10 years, the basal land-capability yield of rice and wheat increased obviously, which was closely related with the update of crop varieties and cultivation modes, and the continuous promotion of cultivated land quality.
