| 摘 要： | 在研究雷州半岛土壤特殊的强固磷机理基础上，以改性的工农业废弃物作为活化剂，活化磷矿粉制得高效磷肥，不仅利用了废弃物资源，变废为宝，而且节省了硫酸资源，降低了肥料成本。在雷州半岛不同地区，以西瓜、甘蔗、辣椒、水稻为供试作物，以过磷酸钙为对照，在等质量(低成本)条件下进行了大量的田间试验，结果表明，除水稻产量持平外，其他作物均表现出明显的增产效果，增产幅度在3％-22％之间，且产品品质改善。因此，高效磷肥在雷州半岛地区有广阔的应用前景。 |

| Abstract: | Based on the studies of the mechanisms of specially strong fixation of P in the soils in Leizhou Peninsula, high efficient phosphoric fertilizers were made by using the modified industrial and agricultural wastes as activated agents to activate ground phosphate rock. These new fertilizers not only utilized the wastes from industry and agriculture, and converted them into resources, but also saved the resources of sulfuric acid and decreased the cost of fertilizers. By using watermelon, sugarcane, capsicum and rice as the tested crops, superphosphate as the control fertilizer, several field experiments of high efficient phosphoric fertilizers were carried out in Leizhou Peninsula. The results showed that the high efficient phosphoric fertilizers had obvious effects on yields and the quality of products was improved, and the yields was increased from 3% to 22% except rice that had almost the same yield as that of the control. Therefore, high efficient phosphoric fertilizers had wide prospects of application in Leizhou Peninsula. |
