去年我所在早、晚两季水稻上,作了叶面喷施硼、钼、锌等微量元素肥料的试验,取得明显的增产效果。试验结果说明,用硼、锌、钼等微量元素配成一定浓度的溶液,在水稻适当的生育期,喷施于叶面,其增产率分别达到19.7％、17.1％、13.2％, Last year, I was on the rice in the early and late seasons, and the experiment of spraying the trace element fertilizers such as boron, molybdenum and zinc on the foliage was made and the yield was obviously increased. The results showed that the yield was 19.7%, 17.1% and 13.2%, respectively, when the solution was sprayed on the foliage at the proper growing stage of rice with the concentration of trace elements such as boron, zinc and molybdenum.
