摘　　要：试验旨在探究呼伦贝尔地区‘福燕70’优质高效生产的最佳行距配置。试验采用单因素随机区组设计,研究15、20、25、30、35 cm行距配置对‘福燕70’产量和青贮品质的影响,采用灰色关联度进行综合评价。结果显示,行距配置对‘福燕70’的干物质产量和青贮品质有显著影响(P<0.05)。‘福燕70’干物质产量在行距为20 cm时最高,为10 629 kg/hm~2;干物质(DM)含量在行距25 cm时最高,为36.79%;粗蛋白(CP)含量在行距30 cm时最高,为13.40%DM;粗脂肪(EE)含量在行距30 cm时最高,为2.75%DM;酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)含量随种植行距的增加明显提高;ADF含量在行距20cm时最低,为25.11%DM。灰色关联分析表明,行距为20 cm时,‘福燕70’的综合评价最高,关联度为0.948。研究表明,‘福燕70’在种植行距为20 cm时,干物质产量高,青贮品质优,适宜在呼伦贝尔地区种植。The study was to explore the optimal row space configuration for high-quality and efficient production of'Fuyan 70'in Hulun Buir area.A single factor randomized block design was used to study the effect of row spacing of 15,20,25,30 and 35 cm on yield and silage quality.The grey relational degree was used for comprehensive evaluation.The results showed that row spacing configuration had significant effect on dry matter yield and silage quality(P<0.05).The maximum dry matter yield of'Fuyan 70'was 10629 kg/hm’when the row spacing was 20 cm.DM content was the highest(36.79%)at row spacing was 25 cm,CP content was the highest(13.40%)at row spacing of 30 cm,EE content was the highest(2.75%)at row spacing of 30 cm,ADF and NDF content increased significantly with the increase of planting row spacing,and ADF content was the lowest(25.11%)at row spacing of 20 cm.Grey correlation analysis showed that the comprehensive evaluation of row spacing of 20 cm was the highest,the correlation degree was 0.948.The experiment indicates that when planting row spacing is 20 cm,'Fuyan 70'has high dry matter yield and excellent silage quality,which is suitable for planting in Hulun Buir area.
