为了探讨团粒法和熔体塔式造粒工艺生产的相同养分组成的硫基复合肥对作物产量和肥料利用效率的差异,以小白菜为研究对象,开展了盆栽试验。试验结果表明:2种工艺生产的硫基复合肥对根冠比、叶绿素积累及叶菜生长发育差别不大,但高塔熔体塔式造粒工艺生产的硫基复合肥在促进氮素吸收和根系生长,提高鲜重、地下部干物质利用效率和产量方面具有一定优势。
A pot experiment on pakchoi has been carried out to compare the crop yield and fertilizer efficiency of sulphur-based compound fertilizers with the same nutrient contents produced by the agglomeration process and the melt prilling process. The result showed that there was no significant difference in the root-shoot ratio, the chlorophyll accumulation and the leaf vegetables growth between fertilizers produced by two processes, whereas sulphur-based compound fertilizer produced by the melt prilling process was more efficient in promoting the nitrogen uptake and the root growth, increasing the fresh weight, the utilization rate of the dry matter below-ground part and the crop yield.
