摘要
介绍了部分酸化磷矿一步法制复合肥的肥效及水溶磷在土壤中的退化机理。说明控制化肥中适当的水溶磷比例 ,可以减少土壤对磷的固定 ,提高施肥效果。
The effect of partially acidulated phosphate rock compound fertilizer and the degeneration mechanism of water soluble phosphate in soil were introduced.It was shown that if the proportion of water soluble phosphate was controlled properly,the fixation of phosphate in soil would be decreased,and the effect of fertilization would be improved.
