| 摘 要： | 小麦田对氮肥需求和施肥时间的要求非常严格。在种植中,常见叶片短、窄,茎部叶片先发黄;植株瘦小、直立,分蘖少,穗粒少而小。合理的施氮时间是影响小麦产量的最主要因素。氮肥是小麦生长所必需的大量元素。因此,合理施用氮肥对小麦生长至关重要。

| Abstract: | Fields of the demand for nitrogen fertilizer and fertilization time requirement is very strict. Leaf is short, narrow, and stem leaves yellowing first. Plant slender, erect, less tillers, grain is little and little. Appropriate nitrogen application time is the most important factor for influencing wheat yield. Nitrogen is essential for wheat growth. So, rational nitrogen application is significant for wheat growth. |
