随着粮食产量的提高和氮磷钾化肥施用量的大幅度增加,一些土壤中微量元素就呈现出缺乏,已成为高产不可缺少的重要元素。我省从1964年开始进行钼肥试验示范和近几年来开展硼肥和锌肥试验示范工作,取得了一定的成效。各地试验示范表明,一般施用钼、硼、锌等微量元素肥料,能促进作物生长发育,早熟,有着比较明显的增产
With the increase of grain yield and the significant increase of NPK fertilizer application, trace elements in some soils are lacking and have become indispensable and important elements of high yield. In 1964, our province began to carry out experimental demonstration of molybdenum fertilizer and pilot and demonstration work of boron and zinc fertilizer in recent years, and achieved some success. Tests and demonstrations show that the general application of trace elements such as molybdenum, boron, zinc and other fertilizers, can promote crop growth and development, early maturity, with a more obvious increase
