摘  要:
在冀中南地区小麦/玉米轮作制度自然生产条件下,对2 m土体磷素周年循环及盈亏变化进行了研究,并提出了磷素高效利用的施用方法。结果表明:小麦/玉米轮作土体磷素含量周年变化呈"M"型;磷素纵向移动性差,多累积于耕层,周年变化幅度随土层的加深而变小;当前生产条件下,小麦/玉米轮作磷素循环呈盈余状态,磷肥施用应以减为主,在施用上以全部或重施于小麦效果较好。

摘  要:
Under the natural production conditions of wheat and maize rotation system in central-south of Hebei Province,the annual cycle and loss changes of phosphorus in 2 m soil were studied and the phosphorus application methods for efficient utilization was put forward. The results showed that the annual variation of phosphorus content showed M type in wheat and maize rotation system,phosphorus longitudinal movement was poor,which mostly accumulated in the topsoil,and the annual variation amplitude was smaller with the deepening of the soil. Under current production conditions, phosphorus cycle showed a surplus state in wheat and maize rotation system, phosphate fertilizer should be reduced based on application or re-applied to the whole wheat.
