摘  要：
[目的]研究陕南小麦氮肥追施最佳时间和最佳用量,为陕南地区小麦生产中氮肥的合理施用提供理论依据。[方法]以汉麦6号为供试品种,分别在冬灌期、拔节期进行1次或2次追施氮肥,通过产量及其构成要素和经济系数等指标,研究不同施用时间和不同纯氮施用量对小麦产量的影响。[结果]同等纯氮施用量下,1次追肥,以拔节期追肥效果最好,其中,追施纯氮69.00 kg/hm2时,产量最高,达8 751.90 kg/hm2,其次为追施纯氮103.50 kg/hm2时,产量为8 623.20 kg/hm2;当纯氮施用量高于69.00 kg/hm2时,拔节期1次追肥效果优于冬灌拔节2次追肥。追施纯氮34.50 kg/hm2时,2次追施的小麦产量高于拔节期1次追施。[结论]拔节期1次追施纯氮69.00 kg/hm2时,小麦产量最高,效益最好。

摘  要：
[Objective] The aim was to study the optimal time and dosage of nitrogen fertilizer topdressing on wheat in southern Shaanxi,to provide theoretical basis for reasonable fertilization of nitrogen in wheat production. [Method] With Hanmai 6 as tested varieties,1 time or 2times nitrogen fertilizer topdressing was conducted in winter irrigation period and shooting stage respectively,effects of different applying time and pure nitrogen application amount on wheat were studied through indicators such as yield,components and economic coefficients. [Result]Under the same amount of pure nitrogen,69. 00 kg / hm2 in jointing stage topdressing one time was the best,with the yield of 8 751. 90 kg / hm2,the amount of pure nitrogen at 103. 50 kg/hm2 Followed,with the yield of 8 623. 20 kg / hm2; when the fertilization amount of pure nitrogen was above 69. 00 kg / hm2,1 time topdressing in jointing stage was better than 2 times topdressing in winter irrigation. When topdressing pure nitrogen was 34. 50 kg / hm2,wheat yield by 2 times topdressing was higher than 1 time topdressing in jointing stage. [Conclusion]The amount of pure nitrogen at 69. 00 kg / hm2 in jointing stage topdressing 1 time is the best.
