土壤施硒肥增加粮食硒含量防治大骨节病效果的研究

Effect of applying selenium fertilizer to improve soil and increase selenium level of food on prevention and treatment of Kashin-Beck's disease

本文介绍了一种防治大骨节病的新方法,即:对土壤施硒肥可使小麦硒含量提高到非病区水平,并增加麦粒中多种人体必需氨基酸的含量,同时使病区居民的膳食硒日摄入量由6.7微克增加到21.2微克,从而在短期内即可收到良好的防治效果。

It has been proved by much research work in the last decade that the Kashin-Beck's disease is prevalent among residents are at low Se nutrient metabolic levelin the low selenium environment area。In this paper authors introduce a new me- asure for preventing and curing the disease by applying sodium selenite to farmland and increase the Se content in the staple food from 13 ppb up to 42 ppb inthe disease.The results of this study indicated that increase Se intake by residen-ts has a good curing effect on the metaphyseal part changes and preventive effecton developing new patients of K.B.disease.
