| 摘 要： | 本研究通过大田试验对常用的6个青贮玉米（Zea mays L.）品种在川中丘陵区夏播情况下的适应性进行了比较，结果表明：‘雅玉青贮26号’全株产量、籽粒产量和营养品质综合表现最好，干物质产量、籽粒产量和粗蛋白质产量均最高。相关分析表明，青贮玉米生物产量与株高呈显著正相关（P<0.05），籽粒产量与穗行数、行粒数、千粒重的乘积呈显著正相关（P<0.05）。

| Abstract: | In the field experiment, the yield, morphological and nutritional quality traits of 6 silage corn (Zea mays L.) varieties were evaluated in the hilly area of central Sichuan basin. Results showed that the biomass yield, grain yield and nutrient quality of the ‘Yayu 26’ were the best. The dry matter yield, grain yield and crude protein yield were also the highest in this test. The correlation analysis showed that the biomass yield of silage maize was positively correlated with the plant height, and the grain yield was positively correlated with the product of ear rows, row grains and 1000-grain weight. |
