农作物产量进入中、高产阶段以后,微量元素的增产作用越来越显著,稀土就是其中的重要一环。1987年以来,我们对农作物施用稀土技术进行了探讨研究,收到了显著的增产效果。一、增产效果几年来我县农作物施用稀土面积达到18.75万亩,总共主副产品新增经济效益3050万元,其中小麦累计施用稀土面积13.25万亩,增产小麦640.7万
After the crop yield enters the middle-high yield stage, the increasing effect of trace elements becomes more and more significant. Rare earth is one of the most important elements. Since 1987, we have conducted research on the application of rare earth technology to crops and have received significant stimulation effects. First, the effect of increased production Over the past few years I County County crop area reached 187500 acres of rare earth, a total of 30.5 million yuan of primary and secondary products added economic benefits, including the cumulative use of wheat 13300 acres of rare earth area, an increase of 640.7 million tons of wheat
