研究结果表明,盐城地区内不同自然、农业区(土壤类型)之间土壤平均有效硼含量存在显著的差异。据此,全地区可分为徐淮黄河冲积物黄潮土油菜缺硼区,里下河泻湖相沉积物水稻土油菜缺硼区及沿海冲积海积灰潮土棉花潜在缺硼区等三个区。区以下又可分为14个亚区。
The results show that there is a significant difference in the average effective boron content of soil between different natural and agricultural areas (soil types) in Yancheng area. Accordingly, the whole region can be divided into three areas, namely, the lack of boron in the yellow soil of Xuhuai Yellow River alluvial sediment, the boron deficient area of rapeseed in the Lixiahe lacustrine sediment and the potential boron deficient area of the cotton in the alluvial marine alluvial soil. Sub-district can be divided into 14 sub-regions.
