| 摘 要： | 依托在黄土高原半干旱旱农区建立的不同培肥措施的田间定位试验,以不施肥(NA)为对照,研究4个等氮量的不同培肥措施单施化肥(CF)、单施商品有机肥(SM)、商品有机肥+化肥(SC)和单施玉米秸秆(MS)对旱作玉米水氮利用效率及经济效益的影响。结果表明,单施化肥和有机无机配施显著提高了玉米产量及水氮利用效率,与不施肥相比,单施化肥和商品有机肥+化肥配施处理子粒产量、生物产量和水分利用效率分别增加了148.8%、136.5%、70.8%和105.7%、70.8%、81.6%。与单施化肥相比,商品有机肥+化肥、单施商品有机肥、单施玉米秸秆处理氮肥农学利用效率和氮肥偏生产力分别降低了20.37%、83.97%、12.19%和50.18%、73.78%、44.14%。单施化肥处理和施商品有机肥+化肥处理均可提高玉米产量、生长期耗水量、水分利用效率、氮肥农学利用效率和氮肥偏生产力,施商品有机肥+化肥产投比低于单施化肥。

| Abstract: | This study was carried out based on a long-term soil amendment experiment located in semiarid Loess Plateau. The objective was to determine the effects of different amendments on water and nitrogen use efficiency and economic benefits of maize in semiarid Loess Plateau. The treatments included no amendment(NA) and four amendment treatments with same nitrogen and phosphate input:chemical fertilizer(CF) and commercial organic fertilizer(SM), commercial organic fertilizer plus chemical fertilizer(SC) and maize straw(MS). The results showed that:chemical fertilizer(CF) and commercial organic fertilizer plus chemical fertilizer(SC) treatments significantly increased maize yield and water and nitrogen use efficiency. Compared to no amendment treatment, chemical fertilizer(CF) and commercial organic fertilizer plus chemical fertilizer(SC) treatments increased grain yield, biomass and water use efficiency by 148.8%, 136.5%, 70.8% and 105.7%, 70.8%, 81.6%, respectively. Agronomic N use efficiency and nitrogen partial factor productivity under the commercial organic fertilizer plus chemical fertilizer(SC), commercial organic fertilizer(SM), and maize straw(MS) treatments were significantly decreased by 20.37%, 83.97%, 12.19% and 50.18%, 73.78% and 44.14%, respectively. Both chemical fertilizer(CF) and commercial organic fertilizer plus chemical fertilizer(SC) treatments,have similar effects on yield, water consumption, water use efficiency, agronomic N utilization efficiency and nitrogen partial factor productivity of maize. But the output and input ratio under commercial organic fertilizer plus chemical fertilizer treatment was lower than under single application fertilizer. |
