摘　　要：为了明确优质强筋小麦品种的氮肥运筹,以陕禾192和陕禾1028为材料,开展了不同施氮量对2个小麦品种产量及其构成因素的影响试验。结果表明,2020年陕禾192在施氮量为180 kg/hm^(2)时产量最高,2个年度陕禾1028均在施氮量为120 kg/hm^(2)时产量最高。2个品种在年际间表现出较高的施氮量能提高有效成穗数,但会显著降低千粒重,由此导致减产;2个品种的穗粒数在高施氮量、倒春寒条件下极显著降低。In order to clarify the nitrogen application of high-quality and strong gluten wheat varieties,Shanhe 192 and Shanhe 1028 were used as materials to conduct the test of effects of different nitrogen application rates on yield and its yield components of the two wheat varieties.The results showed that the yield of Shanhe 192 was the highest when the nitrogen application rate was 180 kg/hm^(2) in 2020,and the yield of Shanhe 1028 was the highest when the nitrogen application rate was 120 kg/hm^(2) in two years.The two varieties showed that the higher nitrogen application rate could increase the number of effective ears,but significantly reduce the 1000-grain weight,resulting in a reduction in yield;the grains per panicle of the two varieties decreased significantly under the conditions of high nitrogen application rate and cold spring.
