土壤普查土样化验结果表明,我县水田缺钾面积占总面积67.1％,缺磷面积占水田总面积91.6％。这说明以往我县在施肥问题上,存在着“重化肥,轻农家肥”、“重氮肥,轻磷钾肥”的倾向。一九八一年各级领导重视土普成果应用,积极开展因土施肥的试验示范和推广工作,已收到良好的增产效果。据不完全统计,一九八一年我县共推广钾肥、复合肥20080担,施用面积,占水田总面积64.9％,较合理地调整了土壤中氮、磷、钾的比例。在其它措施的配合下,一九八一年全县单季稻总产比一九八○年增产23.4％,单产提高103斤。
The result of soil sample survey showed that the area of potassium deficiency in paddy field of our county accounted for 67.1% of total area, and the area of phosphorus deficiency accounted for 91.6% of the total paddy field. This shows that in the past, my county fertilizer problems, there is a “heavy chemical fertilizer, light agricultural fertilizer”, “heavy nitrogen fertilizer, phosphorus and potassium” tendency. In 1981, leaders at all levels attached great importance to the application of Tu Pu achievements and actively carried out pilot demonstration and popularization work on soil fertilization. They have received good stimulation results. According to incomplete statistics, in 1981, our county promoted a total of 20080 dan of potash fertilizer and compound fertilizer and applied area accounting for 64.9% of the total paddy field area. The proportion of nitrogen, phosphorus and potassium in soil was reasonably adjusted. With the cooperation of other measures, the total output of single-season rice in the whole county in 1981 increased by 23.4% over that in 1980, with a yield increase of 103 kg.
