| 摘 要： | 在与过磷酸钙生产类似的亚艺条件下，在磷矿粉中加入一定比例的添加剂，研制出3种改性磷肥。化学分析结果表明，在改性磷肥有效磷中，水溶性磷比例下降。盆栽试验结果显示，在等质量施肥条件下，3种改性磷肥均有较大幅度的增产，且植株吸磷量和磷含量有显著的增加。

| Abstract: | In the process similar to the production of superphosphate, different proportional additives were added to ground phosphate rock to produce three modified phosphorus fertilizers. The chedrical analysis shows that the proportion of water-soluble phosphorus in available phosphorus in the modified phosphorus fertilizers has been decreased. Meanwhile the pot experiment shows that three modified phosphorus fertilizers have more positive effect on increasing biomass than that of ordinarily superphophate under the condition of equivalent mass. Moreovef, phosphorus uptake by plant and phosphorus content of plant also increases remarkably. |
