本研究在黄土高原的陕西省彬县大骨节病和克山病重病区，进行小麦、蔬菜的叶面喷Ｓｅ和主食加Ｓｅ防治地方病的示范研究。结果显示，喷Ｓｅ小麦含Ｓｅ量达０．０８１μｇ／ｇ，明显高于未喷Ｓｅ的小麦（０．００９μｇ／ｇ）；示范点膳食含Ｓｅ达０．０７６μｇ／ｇ，显著高于对照点（０．０１４μｇ／ｇ）；示范点人均日摄Ｓｅ量由１３．４０μｇ／ｇ提高到６０．３９μｇ／ｇ；大骨节病Ｘ线阳性检出率由４３．３３％下降到６．４５％，达到国家控制标准。
In this study, a pilot study was conducted on the prevention and control of endemic diseases in wheat and vegetable foliar spray Se and staple food with Septoria nodosum and Keshan disease in Binxian County of Shaanxi Province in the Loess Plateau. The results showed that the Se content in Se wheat was 0.081 μg / g, which was significantly higher than that of wheat without Se spraying (0.009 μg / g). The content of Se in Se wheat was 0.076 μg / g, which was significantly higher than that of the control 0.014μg / g). The average daily dose of Se was increased from 13.40μg / g to 60.39μg / g in the demonstration area. The positive rate of X-ray in Kashin-Beck disease decreased from 43.33% to 6.45% National control standards.
