摘要
对磷尾矿进行综合开发与合理利用是当前我国磷矿产业亟须解决的问题.在复合肥中添加磷尾矿替代磷石膏作填充料,从复合肥的物理性质和田间肥效等方面分析,探索磷尾矿在复合肥中的应用效果.结果表明,15-5-5配方复合肥中添加磷尾矿后颗粒崩解性提高,养分释放速率较快,玉米苗期植株对磷、钙、镁吸收量升高,但钾元素在土壤中流失,导致植株钾吸收量减少;13-5-7配方复合肥中添加磷尾矿,与添加磷石膏相比,复合肥崩解性略有提高,植物对钾吸收量增加.
Abstract
The comprehensive development and rational utilization of phosphorus tailings has always been a prominent problem that urgently needs to be solved in China's phosphate rock industry.By adding phosphorus tailings to compound fertilizers instead of phosphogypsum,the application effect of compound fertilizers is explored through analysis of the physical properties and field fertilization efficiency.The results show that the particle disintegration of the 15-5-5 compound fertilizer is increased when added phosphorus tailings,the nutrient release rate is faster,and the uptake of phosphorus,calcium,and magnesium by corn seedling plants increases,however,potassium is lost in the soil,leading to a decrease in plant uptake.Compared to adding phosphogypsum,the disintegration of the 13-5-7 compound fertilizer added phosphorus tailings is improved slightly,and the uptake of potassium by plants is increased.
