| 耕地质量调查是科学反映耕地质量状况的有效途径，惠水县耕地质量地球化学调查评价是贵州省耕地质量地球化学调查评价项目的子项目之一，涟江大坝是其中的重点工作区域。通过对表层土壤的采样与检测分析，发现涟江大坝耕地土壤酸碱度主要表现为中性和酸性，养分元素有“富N，贫P、K”特征，养分综合为中等至丰富等级的耕地占比超过九成，环境综合质量等级基本全部为安全利用及优先保护类，耕地土壤质量综合几乎均为中等至优质等级，可安全利用富硒耕地占比超过98%。涟江大坝耕地土壤的以上各种指标均明显优于全县耕地，具有极高的开发利用价值。结合涟江大坝的耕地质量现状，提出了发展富硒农产品、优质高附加值农产品的农业产业方向，并建议控制施用氮肥、针对性补充施用磷肥、广泛增施钾肥。 |

| The cultivated land quality survey is a effective way to reflect the cultivated land condition scientifically, the cultivated land geochemical survey of Huishui is a subproject of Guizhou cultivated land geochemical survey, Lianjiang intermountain basin is the important working area. By sampling and detection analysis of surface soil, it’s found that the pH value of cultivated land in Lianjiang intermountain basin mainly is neutral and acid, the nutrient element has the characteristics of rich N and poor P and K, the cultivated land with middle to high class nutrient is more than 90 %, the environmental quality comprehensive degree almost is security utilization and priority protection, the cultivated land quality is almost middle to high quality, the available safe Se-rich cultivated land is more than 98%. the above index of Lianjiang intermountain basin is better than the cultivated land of the county obviously, so it has high value of utilization. According to the cultivated land quality condition of Lianjiang intermountain basin, the agricultural development direction of Se-rich agricultural product and high quality and high value added agricultural product are suggested, it’s also suggested to control the nitrogen fertilizing, fertilize pHospHate targeted and add potash fertilizing widely. |
