【摘要】：以小麦为研究对象,通过田间小区试验对生育期内水肥耦合条件下小麦根系层(0~100 cm)总磷浓度迁移过程的监测,系统分析了不同灌水量(高水7.6 mm、低水6.1 mm)及不同施肥量下(高肥125 kg/hm~2、低肥75 kg/hm~2)总磷在根系层的迁移转化规律。
[Abstract]:A field plot experiment was conducted to monitor the transport of total phosphorus in wheat root layer (0 ~ 100 cm) under the condition of water and fertilizer coupling during the growing period. Different irrigation amounts (high water content 7.6 mm,) were systematically analyzed. Migration and transformation of total phosphorus in root layer under low water 6.1 mm and different fertilization rates (high fertilizer 125 kg/hm~2, and low fertilizer 75 kg/hm~2).
