摘　　要：在同株距条件下,选用陇糜11号和晋黍9号为试验材料,设置等行距与4种宽窄行距配置共5种种植方式,研究其对晋中地区种植糜子农艺性状及产量的影响。结果表明,5种种植方式无论在品种内还是品种间表现都各不相同;陇糜11号和晋黍9号都是在T2处理(宽行40 cm、窄行30 cm)时产量最高,分别为4056.99,5766.69 kg/hm^2;影响产量的主要农艺性状单穗质量、单穗粒质量、有效穗数也都是在T2处理时最大;2个品种的千粒质量虽不是在T2处理时最大,但都与各自的最大千粒质量相近,各处理之间无差异。因此,适宜的宽窄行种植较等行距种植可有效协调作物群体结构与植株个体功能间的关系,通过改善作物通风透光性,提高整体光能利用率,增加光合产物积累,使作物获得高产。从整体来看,晋黍9号比陇糜11号产量高,说明在晋中地区更适合种植晋黍9号。Under the condition of uniform plant spacing,Longmei 11 and Jinshu 9 were selected as the material with equal row spacing and 4 wide and narrow row spacing,and their effects on agronomic characters and yield of millet planted in central Shanxi were studied.The results showed that the performance of the five different planting methods was different within and among varieties.For single yield traits,the yield of Longmei 11 and Jinshu 9 were the highest in T2(wide behavior 40 cm,narrow behavior 30 cm),the highest yields were 4056.99,5766.69 kg/hm^2,respectively.The values of several major agronomic traits that affected yield,such as single ear quality,single ear grain quality and effective ear number,were also the largest at T2.Although the 1000-grains quality of the two varieties was not the largest at T2,they were all similar to the maximum quality of the respective 1000-grains quality,and there were no difference between the treatments.Therefore,suitable wide and narrow row planting can effectively coordinate the relationship between crop population structure and individual plant function,improve the ventilation and light transmittance of crops,improve the overall utilization rate of light energy,increase the accumulation of photosynthate,and make crops obtain high yield.On the whole,the yield of Jinshu 9 is higher than Longmei 11,indicates that Jinshu 9 is more suitable for planting in Jinzhong area.
