摘要:

本研究旨在综合评价滇中南华地区的土壤养分、土壤环境、土壤质量和绿色富硒富锗产地土壤环境质量。通过分析在滇中南华地区开展的1:250000土地质量地球化学调查工作获得的630份表层土壤样本数据,依据国家和行业相关标准对上述指标进行评价。结果显示,研究区土壤养分总体为中等—较丰富水平,一等、二等养分充足的土壤占37.19%,三等土壤占42.35%;土壤环境整体较好,一等土壤(无风险)占比达到80.19%,二等土壤(风险可控)占比为19.41%,三等土壤(风险较高)占比仅为0.40%;土壤质量综合等级总体为优质—良好水平,一等(优质)和二等(良好)土壤占比达到60.26%;达到AA级绿色富硒产地标准的土壤占比为2.78%,面积为63 km2;达到AA级绿色富锗产地标准的土壤占比为28.5%,面积为646 km2;达到AA级绿色富硒富锗产地标准的土壤占比为2.78%,面积为63 km2。研究区土壤养分较为充足,土壤环境总体较好,具有发展绿色富硒富锗食品的广阔前景。本研究对在滇中地区建立绿色富硒富锗种植、养殖实验基地以及开发绿色富硒富锗农畜产品提供了科学依据,助力了南华地区生态农业建设、地方经济发展和乡村振兴事业,对滇中地区发展绿色农业和土地利用规划有一定的参考作用。

Abstract:

The study aimed to master the soil nutrients, soil environment, soil quality and soil environmental quality of green selenium-rich and germanium-rich production areas in Nanhua of central Yunnan. Based on the 630 surface soil samples data obtained from the 1:250000 land quality geochemical survey in Nanhua of central Yunnan, the soil nutrients, soil environment, soil quality and soil environmental quality of green selenium-rich and germanium-rich production areas in Nanhua County were evaluated according to relevant national or industry standards. The results showed that soil nutrient content in the study area was medium-highly rich, with 37.19% of the soil having sufficient nutrients of the first and second grades, and 42.35% of the soil having sufficient nutrients of the third grade. The overall soil environment was good, with first-grade soil (risk-free) accounting for 80.19%, second-grade soil (risk-controllable) accounting for 19.41%, and third-grade soil (higher risk) accounting for only 0.40%. The comprehensive grade of soil quality was generally high-quality and good, and the proportion of first-grade (high-quality) and second-grade (good) soil reached 60.26%. The proportion of soil that meets the AA grade green selenium-rich production area standard was 2.78%, and the area was 63 km2. The proportion of soil that meets the AA grade green germanium-rich production area standard was 28.5%, and the area was 646 km2. The proportion of soil that meets the AA grade green selenium-rich germanium production area standard was 2.78%, and the area was 63 km2. The soil nutrients in the study area were relatively sufficient, the soil environment was generally good, and it had broad prospects for the development of green selenium-rich and germanium-rich foods. This study provided a scientific basis for the establishment of a green selenium-rich and germanium-rich planting and breeding experimental base and the development of green selenium-rich and germanium-rich agricultural and livestock products in central Yunnan, and contributed to the construction of ecological agriculture, local economic development and rural revitalization in Nanhua area, it also had a certain reference effect on the development of green agriculture and the land use planning in central Yunnan.
