【摘要】：以小麥為研究對象,通過田間小區(qū)試驗對生育期內(nèi)水肥耦合條件下小麥根系層(0~100 cm)總磷濃度遷移過程的監(jiān)測,系統(tǒng)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)總磷在根系層的遷移轉(zhuǎn)化規(guī)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).
