摘　　要：为探讨施氮量对当地酿造糯高粱产量的影响,设置9个施氮梯度,研究了淮北酿造糯高粱4个杂交种的最佳施氮量。结果表明:随着施氮量的增加,酿造糯高粱产量呈先升后降的抛物线变化趋势,施氮量240 kg/hm^(2)左右经济效益最佳;晋杂23产量偏低不建议种植,晋杂36、汾粱30和晋杂22产量高但易招致螟虫危害,种植时扬花前要注意防治高粱螟。In order to discuss the effect of nitrogen application rate on the yield of local brewing glutinous sorghum,9 nitrogen appli‐cation gradients were set up to study the optimal nitrogen application rate of 4 hybrids of brewing glutinous sorghum in Huaibei area.The results showed that with the increase of nitrogen application,the yield of brewing glutinous sorghum showed a parabolic trend of first rising and then decreasing,and the best economic benefit was about 240 kg/hm^(2).Jinza 23 had low yield,is not recommended to plant,Jinza 36 Fenliang 30 and Jinza 22 had high yield but easy to cause the harm of borers,planting before flowering should pay at‐tention to control sorghum borer.
