| 摘 要： | 为比较石灰性土壤氮锌配施对不同小麦品种生长及锌营养的影响,选10种本地主要种植小麦品种,进行连续两年的田间试验,测定小麦产量及锌含量。结果表明,在石灰性土壤上单施锌肥和氮锌配施对小麦产量、籽粒锌含量的影响因品种而异。单施锌肥及氮锌配施处理可显著增加土壤有效锌含量,但单施锌肥处理仅增加"西杂1号"、"武农148"、"郑麦9023"籽粒锌含量;氮锌配施增加除"小偃22"外其余9种供试小麦品种籽粒锌含量,增幅为7.3%～54.7%。单施锌肥对小麦锌累积量增加的效果不明显;氮锌配施可显著增加小麦地上部锌累积量,两季分别增加6.5%、29.8%。单施氮肥可显著增加小麦锌吸收,但其主要累积在小麦茎叶部。在石灰性土壤上,单施锌肥虽显著增加了土壤有效锌含量,但对小麦产量及籽粒Zn含量增加有限,氮锌肥配施可取得较好效果。 |

| Abstract: | A two-year experiment was conducted to investigate the effects of combination use of Zn and N fertilizers on growth and Zn content in 10 varieties of winter wheat in calcareous soils.Results show that the effects of sole application of Zn fertilizer and combination use of Zn and N fertilizers on yield and grain Zn content are significantly different among various varieties of winter wheat.Soil content of DTPA-Zn significantly increases in Zn or Zn and N fertilizers treatments.Zn significantly increases grai... |
| Keywords: | Wheat Combination use of Zn and N fertilizers Zn content Zn uptake Zn translocation ratio Calcareous soil |
