摘要
砂基栽培中的磷素淋溶损失不仅造成肥料利用率降低、农业生产成本上升,还能引起地下和地表水体富营养化。在综合中外有关文献的基础上,阐述了砂基栽培磷素淋溶问题的提出、影响磷素淋溶的因子、防治方法,并对砂基栽培磷素淋溶及其防治作了展望。
The loss of phosphorus（P） leaching from substrate soilless culture systems will not only lead to a decrease in the utilization ratio of fertilizers and an increase cost of horticultural production, but also give rise to the eutrophication of surface water and ground water bodies. Based on integrated relevant literature, this paper elaborates the outset of the problems, the affecting factors of P-leaching and the prevention and cure method. Practical and innovative measures will be employed for the control of horticultural P-leaching to water.
