稀土农用研究是一项开拓性课题,1982年正式列入“六五”期间国家重点科技攻关项目内容.多年试验证明,合理施用稀土确能使水稻、小麦、大豆……等多种农作物增产增收;对一些作物有一定的改进品质的作用;适量施用稀土,可加强植物体的某些生理机能:卫生学初步鉴定表明,稀土属低毒物质,在“三致”(致癌、致畸、致突变)试验中,未见阳性反应,对土壤、粮食进行的比放射性测定可见,使用稀土后与其自然本底未见差异.总之,从稀土农用的全国性多学科综合研究所取得的一系列进展和成果来看,稀土农用的前景是广阔的.
Rare earth agricultural research is a pioneering topic, formally included in the national key scientific and technological project during the “Six Five” period in 1982. Years of experimentation has proved that rational use of rare earth can make a variety of crops such as rice, wheat, soybeans and other crops increase production ; Some crops have a certain quality improvement effect; Appropriate amount of rare earth, can enhance some physiological functions of plants: Preliminary identification of hygiene shows that rare earth is a low toxic substances, in the “three” (carcinogenic, teratogenic, induced Mutation) test, there was no positive reaction, and the specific radioactivity of soil and grain could be seen, but no difference was found between the use of rare earth and its natural background. In conclusion, a series of progress made from the national multidisciplinary comprehensive research of rare earth agriculture And the results, the prospects for rare earth agriculture is vast.
