| 摘 要： | 通过土壤农化样品及剖面样品的养分含量分析、实验室吸附试验及幼苗法盆栽试验 ,初步明确 :江苏沿海轻质脱盐土因洗盐等作用 ,造成作物根系分布层土壤水溶性镁含量极低、交换性镁含量相对不足 ,速效性钾含量处于缺乏临界水平。因此 ,在这类脱盐土上提倡镁、钾配合施用更有利于作物生长 |

| Abstract: | Analysis of the soil samples from both plowed layer and profile, laboratory adsorption experiment and plumelet potted experiment were conducted. The results showed that the soluble Mg content of root distributed soil layer was extremely low, the exchangeable Mg relatively was deficient, and quick available K was at critical level because of the salt washing action of the light desaline soil of inshore areas of Jiangsu. Therefore, coordinated application of Mg and K benefits plant growth. |
| Keywords: | desaline soil Mg K |
