摘　　要：通过分析气象因子与高粱单株产量形成之间的关系,找出影响高粱单株产量的主要气象因子。选用齐杂107、风杂103、齐杂104、吉杂159、齐杂5、齐杂772、齐杂33等多个高粱品种,在科右前旗居力很镇红心村绿色智慧农业科技示范园区种植,并记载生育时期、逐日气象因子及成熟后单株产量。结果表明,对高粱单株产量影响最大的气象因子为最低温度,影响最小的气象因子为最高温度,不同品种在全生育期内气象因子与单株产量间的回归方程模型为:y=169.82+0.106x_(1)+0.819x_(2)+0.264x_(3)+0.394x_(4)-0.104x_(5)-0.116x_(6)-0.517x_(7)。By analyzing the relationship between meteorological factors and the formation of the yield per plant of sorghumt,the main meteorological factors affecting the yield per plant of sorghum were found out.Several sorghum varieties such as Qiza 107,Fengza 103,Qiza 104,Jiza 159,Qiza 5,Qiza 772,Qiza 33 were selected and planted in Hongxin Village green smart agricultural science and technology demonstration park,Julihen Town,Horqin Right Front Bannerband,and the fertility period,daily meteorological factors and yield per plant after maturity were recorded.The results showed that the meteorological factor that had the greatest effect on the yield per plant of sorghum was the lowest temperature,and the meteorological factor that had the least effect was the highest temperature.The regression equation model between the meteorological factor and the yield per plant of different varieties during the whole fertility period was as follows:y=169.82+0.106x_(1)+0.819x_(2)+0.264x_(3)+0.394x_(4)-0.104x_(5)-0.116x_(6)-0.517x_(7).
