摘  要：
在大田条件下,以小麦品种济麦22号和花生品种花育25号为材料,设置4种不同追施氮肥的方式,分别为:(A)拔节期施纯氮160kg/hm~2、(B)拔节期施纯氮80kg/hm~2+开花期施纯氮80kg/hm~2、(C)孕穗期施纯氮160kg/hm~2、(D)开花期施纯氮160kg/hm~2;施肥方法均为开沟追施。研究了小麦季4种不同追施氮肥方式对下茬花生各生育时期叶片叶绿素含量、光合速率、成熟期各器官氮素和干物质积累与分配及周年氮素利用效率的影响。结果表明:C处理的氮肥运筹方式提高了叶片叶绿素含量和光合速率;荚果中氮素和干物质积累量及其分配比例均较高;小麦籽粒产量最高、花生荚果产量较高;氮素内部利用效率和氮肥偏生产力均最高。本试验条件下,综合考虑周年作物产量和氮素利用效率,前茬小麦基施纯氮105kg/hm~2、孕穗期追施纯氮160kg/hm~2和花针期追施25kg/hm~2(C处理)是小麦套种花生种植模式下最佳的氮肥运筹方式。

摘  要：
Field experiment was conducted to examine the effects of nitrogen fertilizer regulation in preceding wheat(Jimai22)on nitrogen and dry matter accumulation and N utilization of peanuts(Huayu25)relay-cropping with wheat.The four nitrogen fertilizer regulations such as topdressing of nitrogen fertilizer 160kg/ha at wheat jointing stage(A),topdressing of nitrogen fertilizer 80kg/ha at wheat jointing and 80kg/ha at wheat anthesis stage(B),topdressing of nitrogen fertilizer 160kg/ha at wheat booting stage(C),topdressing of nitrogen fertilizer 160kg/ha at wheat anthesis stage(D).The results showed that chlorophyll content and net photosynthetic of peanut leaf of treatment C were higher than other treatments.Both dry matter and nitrogen accumulation,and transportation and peanut yield of treatment C were all higher than other treatments.The yield of wheat,N internal efficiency and N partial factor productivity of treatment C were the highest in the experiment.In conclusion,under the condition of the experiment as far as the yield of wheat and peanut and N utilization,the most application productive and effective regime was treatment C(N 105kg/ha basal fertilizer before growing wheat+ N 160kg/ha topdressing fertilizer at wheat booting stage+ N 25kg/ha topdressing fertilizer at pod bearing stage).
