| 摘 要： | 采用大田试验,在小麦季N 250kg /hm2和玉米季N 200kg /hm2氮肥供应条件下,连续2年度（2007～2009）观测了不同施氮模式对冬小麦/夏玉米产量及氮素利用的影响。结果表明,与对照相比,常规施肥、有机无机复合肥、控释复合肥、控失复合肥以及改变氮肥基追配比处理均显著提高冬小麦/夏玉米子粒产量和干物质积累量,小麦季各处理产量大小依次为:控释复合肥控失复合肥有机无机复合肥改变氮肥基追配比常规施肥,提高幅度在107.5%～147.4%;玉米季各处理产量大小依次为:控释复合肥控失复合肥有机无机复合肥常规施肥改变氮肥基追配比,提高幅度在28.5%～56.1%。与常规施肥处理比较,控释复合肥、控失复合肥和有机无机复合肥处理冬小麦氮肥偏生产力和氮肥农学效率提高2.2～5.1 kg/kg,夏玉米提高3.6～7.6 kg/kg;但改变基追配比处理在小麦季高于常规处理,在玉米季则低于当地常规施肥处理。从产量和氮肥利用率方面综合分析,有机无机复合肥、控释复合肥、控失复合肥均可作为适宜研究区域推广的肥料品种,而改变基追配比处理相对较适宜冬小麦季。

| Abstract: | Under the field experiment condition,effects of different nitrogen application patterns on yields of wheat and maize and nitrogen use efficiency were studied during 2007-2009.There were six treatments including no fertilizer(CK),convention fertilizer(CON),organic complex fertilizer(OMF),controlled release fertilizer(CRF),controlled loss fertilizer(CLF) and changing basic fertilizer and topdressing regimes(CBT).There were the same amounts of nitrogen(N) application with 250 kg/ha in wheat season and 200 kg/h... |
