| 摘 要： | 应用腐植酸的活化功能,开发磷的高效利用技术,是当前磷肥科技创新中的重要内容。通过室内模拟和玉米盆栽试验,研究了腐植酸类活化剂对磷铵、钙镁磷肥的促释增效作用。结果表明,高效磷铵有较高的抗土壤固定能力,而活化钙镁磷肥的磷释放量明显提高。在等重的情况下,高效磷铵的肥效与普通磷铵的相当,而活化钙镁磷肥的肥效则优于普通钙镁磷肥。

| Abstract: | Using humic acid substance as activator, exploiting technology of enhancing Puse efficiency is one of the important part of innovation of science and technology of phosphate fertilizers. In this paper, the effects of humic acid activator on promoting-release and enhancing efficiency of ammonium phosphate and fused calcium magnesium phosphate (FCMP) were studied by simulation experiment and pot experiment of corn. The results showed that, compared with common ammonium phosphate, high-efficiency ammonium phos... |
