摘　　要：为提升东北春麦区优质强筋小麦品种龙麦35的原粮“量质兼用”利用价值,本研究以强筋小麦品种龙麦35为试验材料,调查施氮量和种植密度对龙麦35产量和湿面筋含量、稳定时间、能量及最大抗延阻力等品质性状的影响。结果表明:龙麦35产量在年度间存在显著差异,且两年间均表现为施氮量75 kg·hm^(-2)处理大于施氮量90 kg·hm^(-2)处理。产量随着种植密度增加有减小的趋势,650株·m^(-2)处理龙麦35的产量最高。龙麦35品质性状表现为施氮量75 kg·hm^(-2)处理略低于90 kg·hm^(-2)处理,但两个施氮量处理间无显著性差异,3种种植密度对龙麦35品质的影响不显著。说明施氮量75 kg·hm^(-2)和种植密度650株·m^(-2)是龙麦35保质增产关键栽培技术中较为适宜的施氮量和种植密度。In order to improve the utilization value of“quantity and quality”of wheat Longmai 35 grain in northeast spring wheat area,in this study,taking Longmai 35 as experimental material,the effects of key cultivation technologies(such as nitrogen application rate and planting density)on the yield and quality of Longmai 35 were studied.The results showed that,there were significant differences in the yield of Longmai 35 between years,and the nitrogen application rate of 75 kg·ha^(-1) were greater than that of 90 kg·ha^(-1) in both years.The yield of different density treatments decreased with the increase of planting density,and the yield of 650 plant·m^(-2) treatment was the highest.The quality characters of Longmai 35 showed that the nitrogen application rate of 75 kg·ha^(-1) treatment was slightly lower than that of 90 kg·ha^(-1) treatment,but there was no significant difference between the two nitrogen application rates.And the three planting densities had no significant effect on the quality of Longmai 35.In conclusion,nitrogen application rate of 75 kg·ha^(-1) and planting density of 650 plant·m^(-2) are the key cultivation technologies of Longmai 35 with high yield and quality.
