| 摘 要： | 通过探究秸秆还田与生物炭配施对麦-玉轮作体系产量和氮素利用率的影响,为黄褐土粮食生产科学施肥提供指导。本研究选取不施肥(CK)、单施生物炭(B)、单施化肥(NPK)、化肥配施秸秆(NPKS)、化肥配施生物炭(NPKB)和化肥配施生物炭和秸秆处理(NPKBS),分析不同处理对作物产量、养分含量和氮肥利用率的影响。结果表明：秸秆与生物炭配施化肥均可显著提高作物穗粒数、产量、土壤全氮、碱解氮、植株籽粒氮积累量;秸秆与生物炭配施化肥均可以显著提高氮素利用率,且小麦利用率高于玉米,真实利用率较当季利用率提高了17.72%~37.43%,其中化肥配施生物炭和秸秆效果最好。综上,化肥配施生物炭和秸秆可以显著提高作物产量,提高氮素真实利用率。

| Abstract: | To provide guidance for fertilization and grain production on yellow cinnamon soil, straw returning combined with biochar applying was employed to exam the effect on grain yield and nitrogen utilization efficiency in winter wheat-summer maize rotation system. The experiments were conducted with CK (no fertilization), B (only biochar), NPK (nitrogen fertilizer, phosphate fertilizer, potassium fertilizer), NPKS (NPK + straw returning), NPKB (NPK + biochar) and NPKBS (NPKS + biochar), to analyze the effects of different treatments on crop yield, nutrient content and nitrogen utilization efficiency. The results showed that straw and biochar combined with chemical fertilizer could significantly increase grain number per spike, yield, soil available nitrogen and total nitrogen contents, and the nitrogen accumulation in the plant and the grain, and improve the nitrogen use efficiency significantly; the effect of the fertilization on winter wheat was better than that on summer maize, the nitrogen utilization in reality was 17.72%-37.43% higher than of current season, and the NPKBS showed the best effects on the nitrogen efficiency. To sum up, chemical fertilizer combined with biochar and straw could significantly improve crop yield and nitrogen use efficiency. |
