| 摘 要： | 通过对三原—阎良地区土壤与农作物采样分析研究,发现该地区土壤环境总体清洁,足硒—富硒土壤占调查区总面积的94.62%,富硒土壤分布广,具备了开发富硒农产品的基本土壤条件;大宗粮食作物均达富硒水平,其中油菜富硒率100%,小麦富硒率99.4%,玉米富硒率88.1%,大部分蔬菜也都达到了富硒蔬菜的标准,适合种植富硒大宗粮食作物和蔬菜;农作物硒与土壤硒整体相关性较好,玉米硒含量与根系土硒含量相关系数为0.788,小麦硒含量与根系土硒含量相关系数为0.612,富硒产业发展前景好。三原—阎良地区是陕西省关中地区重要的粮食、蔬菜产地,建议选择示范点开展富硒农产品种植试点,为关中地区富硒资源开发利用提供科学依据,在此基础上打造建设一批富硒粮食、蔬菜产业基地,更好地支撑服务乡村振兴战略和精准脱贫攻坚战。

| Abstract: | Through the sampling and analysis of soil and crops in Sanyuan-Yanliang area,it is found that the soil environment in the study area is generally clean.The medium-rich selenium soil accounts for 94.62%of the total survey area,selenium-rich soil is widely distributed and has the basic soil conditions for the development of selenium-rich crop.It has the basic soil conditions for developing selenium-enriched foods.For the analysis of crop products,it can be seen that the bulk crops are selenium-rich crops,and the selenium-enriched level is relatively stable.Some vegetables have also reached the standard of selenium-enriched vegetables.The selenium in crops has a good correlation with soil selenium.The correlation coefficient between the selenium content of corn and that of root soil is 0.788,and the correlation coefficient between the selenium content of wheat and that of root soil is 0.612.Hence the study area has a future for the development of selenium-enriched industries.Guanzhon is suitable for vigorously promoting the cultivation of selenium-enriched crops and vegetables as an important food and vegetable.The production area has great potential for the development of selenium-enriched crops.It is recommended to select demonstration sites to carry out selenium-enriched planting work,and to focus on building a group of selenium-rich grain and vegetable industry bases so as to provide a scientific basis for the development and utilization of selenium-rich resources in Guanzhong,Shaanxi Province,thus supporting the rural revitalization strategy and the precise poverty alleviation battle. |
