摘要
１９９１年，利用冀东地区已有１：２０万区域化探资料，进行了在农业中的开发应用研究，在此基础上，选择区内微量营养元素和有益元素缺乏区，开展了增施微量元素Ｚｎ、Ｍｎ、Ｍｏ、Ｂ和Ｃｏ肥料提高水稻、玉米、花生和苹果产量的应用研究。试验结果表明，增施微肥后，水稻、玉米、花生产量提高，平均增产１０％以上，亩增收入平均４０元以上，苹果增产３０％以上，亩增收入大于１０００元，增产效果和经济效益是明显的。这项成果如在整个冀东地区推广，其经济效益将是巨大的。
In 1991, a study was conducted in eastern Hebei area concerning the application of available 1:200000 regional geochemical data to agricultoral development. On such a basis, afurther test was mado on applying additional fertilizer with more Zn, Mn, Mo, B and Co to an area deficient in trace nutritive elements and aseful element for the purpose of raising the yield of rice, maize, peanut and apple. The result of the test shows that after the application of additional trace element fertilizer, the yield of rice, maize and peanut was raised averagely by 10%, with the income increasing more than 40 yuan per ma, and the yield of apgle was raisedover 30% with the increase of incone higher than 1000 yuan per mu, suggesting obvious yield growth effects and economic benefits. This item of achievement, if spread in whole eastern Hebei area, would surely produce great economic benefits.
