    摘要:

    为确定东北地区中部黑土秸秆还田条件下玉米适宜氮肥用量,于2017-2020年在吉林省公主岭市连续4 a设置定位试验,分析秸秆还田下不同氮肥用量(0、70、140、210、280和350 kg/hm2)对玉米产量、氮肥利用效率和土壤氮素平衡的影响,探讨秸秆还田下氮肥用量与玉米产量及氮素盈余率之间的关系。结果显示,秸秆还田下玉米产量随施氮量的增加呈先增加后降低的趋势,但获得最高产量的施氮量随着试验的开展呈降低趋势,降幅达到了15.8%。玉米累积氮素农学效率、回收率和偏生产力均随着氮肥用量的增加而降低。土壤氮素平衡结果显示,当施氮量超过210 kg/hm2时,显著增加了土壤矿质氮素累积量,与播前土壤相比,在高施氮量下(280和350 kg/hm2),其矿质氮素累积量分别增加了13.0%和33.6%,与此同时,其氮素累积表观损失达到了578和833 kg/hm2。氮素表观盈余率与氮肥用量、籽粒产量、累积氮素回收率和氮素损失量相关性分析结果显示,当盈余率为0时,氮肥用量为188.9 kg/hm2,产量为11 850 kg/hm2,氮素回收率为40.1%,氮素损失量为65.7 kg/hm2。结果表明:秸秆还田下配施适宜氮肥可显著提高玉米产量以及氮素利用率,并能降低土壤氮素表观损失。综合考虑作物产量、理论盈余率及土壤氮素表观平衡等因素,所研究区域长期秸秆还田下适宜氮肥用量为179.5~198.4 kg/hm2

    Abstract:

    In order to determine the appropriate nitrogen (N) fertilizer application rate for maize under straw returning in the black soil of central Northeast China, a site?specific field experiment from 2017 to 2020 was conducted in Gongzhuling County of Jilin Province. The experiment had set 6 different N fertilizer rates (0, 70, 140, 210, 280 and 350 kg/hm2)to analyze the effects of N on maize yield, N fertilizer utilization efficiency and soil N balance under straw returning, and to explore the relationship among N fertilizer rate, maize yield and N surplus rate under straw return. The results showed that the maize yield first increased and then decreased with the increase of N fertilizer application rate under straw returning condition, but the amount of N application to obtain the highest yield was decreasing with the extension of experiment, reduced by 15.8%. The cumulative agronomic efficiency, the recovery efficiency and the partial factor productivity of N application in maize all decreased with increasing rate of N fertilizer application. In additin, soil N residues were significantly increased by 13.0% and 33.6% at high N application rates (280 and 350 kg/hm2) compared with the soil before planting, respectively, while their cumulative apparent N losses reached 578 and 833 kg/hm2. The correlation analysis showed that the N fertilizer rate was 188.9 kg/hm2, yield was 11 850 kg/hm2, N recovery efficiency was 40.1% and N loss was 65.7 kg/hm2 when the surplus rate was 0. The results indicated that the appropriate N fertilizer rate under straw returning conditions could significantly improve maize yield and N use efficiency, and reduce the apparent N loss. Considering the crop yield, theoretical surplus rate and apparent soil N balance, to apply 179.5-198.4 kg/hm2 N fertilizer was the appreciate range under long?term straw incorporation in the experiment region.
