摘要

通过研究施用坡缕石后对氮、磷在红芪田土壤中的形态转化和迁移规律的影响

以期为坡缕石在中药材栽培中的应用提供理论依据。结果表明:0-20 cm土层

1 500 kg/hm2和2 250 kg/hm2用量的坡缕石和氮磷钾肥配施后会在9月份分别较单施氮磷钾肥处理提高30.50%和20.23%的NH4+-N含量。2 250 kg/hm2用量的坡缕石和氮磷钾肥配施后会在7、8、9月份分别较单施氮磷钾肥处理提高24.62%

14.01%

20.37%的NO3--N含量。2 250 kg/hm2用量和750 kg/hm2用量的坡缕石与氮磷钾肥配施后会在8月份分别较单施氮磷钾肥处理提高20.30%和20.50%的速效磷含量。坡缕石和氮磷钾肥配合施用后会对0-20 cm土层的速效氮、磷养分起到保肥的作用。
