| 摘 要： | 用超微细处理、分析测定和温室土培的试验方法研究了两种磷矿粉经不同时间的超微细处理和不同活化剂活化后磷矿粉有效磷含量的变化,以及超微细磷矿粉对小油菜生长指标和吸收氮、磷、钾的影响。结果表明:与未经超微细的低品位磷矿粉相比较,超微细磷矿粉的有效磷释放量显著升高,相同超微细条件下经腐殖酸和沸石活化后有效磷含量显著升高;超微细磷矿粉能够显著促进小油菜的生长和氮、磷、钾的吸收,其中,超微细胶磷矿粉经腐殖酸和沸石活化与过磷酸钙效果相差最小;同一种磷矿粉,超微细处理5h的磷矿粉效果好于超微细处理2h的磷矿粉,相同超微细处理条件下胶磷矿磷矿粉的有效磷释出增加量和生物学效果高于磷块岩磷矿粉。

| Abstract: | The effective phosphorus content and biology effect of superfine phosphorite powder were studied by superfine processing,chemical analysis and greeshouse pot experiment.The results showed that the effective phosphorus content of superfine phosphorite powder is higher than the not superfine phosphorite powder.And the effective phosphorus content of the same phosphorite powder after 5h superfine processing is higher than that after 2h superfine processing.Under the same condition,the collophane effective phos... |
