测定不同时期氮、磷、钾的含量 ,宁杂 1号整个生育期内无论植株还是各个器官的吸收积累量均大于常规油菜。其植株对氮、磷、钾的吸收高峰期长 ,营养在各个时期的分配利用及叶片、角果的光合作用交替与常规油菜相比更为协调 ;氮、磷、钾转化率相对较高 ,单位产品需肥量较少 The contents of nitrogen, phosphorus and potassium in different periods were determined. The accumulation of plant or organ in Ningza 1 was higher than that of conventional canola during the whole growing period. The plant had a long period of peak absorption of nitrogen, phosphorus and potassium, and the utilization of nutrients in different periods and the photosynthesis of leaves and pods were more coordinated than that of conventional rape. The conversion rate of nitrogen, phosphorus and potassium was relatively high, Unit product needs less fat
