近年来,地学、医学等部门通过大量调研证实:大骨节病发生于低硒环境。为了寻求简便、底毒、活性强、利于机体代谢,采用农作物喷硒提高粮食硒含量的方法,颇为可取。现将三年(1981·5—1984·5)的试验X 线效果观察分述于后.实验观察方法一、概况选活跃重病点千阳县水沟乡孟家咀村,在流行病学调查及测定土壤硒(77—94ppb)粮
In recent years, geosciences, medicine and other departments through a large number of research confirmed: Kashin-Beck disease occurs in low selenium environment. In order to seek simple, the end of poison, strong activity, which is conducive to the body metabolism, the use of crop spraying selenium content of grain to increase the method, is quite desirable. Now three years (1981 · 5-1984 · 5) the experimental X-ray effects were observed in the post-observation methods of an overview of the active and active disease survey elected Qiangyang County Shuigou Township Village Meng, in the epidemiological survey And determination of soil selenium (77-94ppb) grain
