对安徽省土壤有效硼含量进行测定的结果表明:安徽省土壤有效硼含量平均为0.37±0.01ppm,有78.2%土壤缺有效硼(<0.50ppm),30.2%土壤极缺(<0.25ppm)。地区分布为:皖西山地<沿江平原<皖南山丘<江淮丘岗<淮北平原。主要土类的含量是砂姜黑土>潮土>棕壤>粗骨土>石灰岩土>黄棕壤、黄褐土>水稻土>紫色土、红壤。不同母质土壤有效硼含量是黄泛冲积物、黄土性古河湖相沉积物>碳酸盐岩风化物、湖积物>长江冲积物>下蜀黄土、河流冲积物>泥质页岩风化物>紫色岩风化物>第四纪红土、酸性岩风化物。耕作层土壤有效硼含量一般比心土层和底土层土壤高0.1—0.2ppm以上;土壤有效硼含量与pH多数呈正相关。
The results showed that the available boron content of soil in Anhui Province was 0.37 ± 0.01ppm on average, 78.2% of the soil had available boron (<0.50ppm) and 30.2% of the soil was scarce (<0.25ppm). The distribution is as follows: Wanxi Mountain tidal soil> brown soil> coarse bark> limestone soil> yellow brown soil, yellow cinnamon soil> paddy soil> purple soil, red soil. The available boron content of different parent materials is yellow pan-alluvial, loess-type Furukawa-lacustrine sediments> carbonate weathering products and sediments> Changjiang alluvial sediments> Xiashu loess and river sediments> shale shale weathering materials> Purple rock weathering> Quaternary laterite, acidic rock weathering material. Soil available boron content in tillage soil is generally more than 0.1-0.2ppm above the soil in the soil layer and the bottom soil layer; soil available boron content is positively correlated with the pH value.
