摘　　要：以15个不同地区的青贮玉米品种为供试品种,种植密度60000株/hm^(2),采用随机区组设计,蜡熟期(R4)进行植物样品采集,测定青贮玉米的产量、农艺性状和营养品质,对15个青贮玉米品种进行综合评价,为山西省北部地区的青贮玉米品种引种资质提供理论依据。结果表明,在产量方面,鲜重高于各品种平均值(52.23 t/hm^(2))的品种为渝青386、北农青贮208、大京九26、雅玉青贮8号和宁单33号。在农艺性状方面,基于对15个青贮玉米品种通径分析得出,要提高青贮玉米的生物学产量,应该选择株高、茎粗和绿叶数等农艺性状突出的品种。在营养品质方面,各品种的粗蛋白含量、酸性洗涤纤维含量和中性洗涤纤维含量分别为8.36%~14.87%、33.42%~41.69%和57.81%~70.13%。通过对15个青贮玉米品种的产量、粗蛋白和相对饲喂价值进行综合评价,得出雅玉青贮8号、北农青贮208等青贮玉米品种适宜在山西省北部地区推广种植。Fifteen silage maize varieties from various regions were tested with a planting density of 60000 plants/ha,and the plant samples were collected at the wax maturity stage(R4)of silage maize by random block de⁃sign,and the yield,agronomic traits and nutritional quality of silage maize were measured,and a comprehensive evaluation of the 15 silage maize varieties was conducted to provide a theoretical basis for the introduction qualifica⁃tion of silage maize varieties in northern Shanxi Province.The results showed that in terms of yield,the varieties with fresh weight higher than the average value of each variety(52.23 t/ha)were Yuqing386,Beinong Silage208,Da⁃jingjiu 26,Yayu Silage 8 and Ningdan 33.In terms of agronomic traits,in order to improve the biological yield of si⁃lage maize,varieties with outstanding agronomic traits such as plant height,stem diameter and number of green leaves should be selected.In terms of nutritional quality,the crude protein content,acid detergent fiber content and neutral detergent fiber content of each variety were 8.36%-14.87%,33.42%-41.69%and 57.81%-70.13%,respec⁃tively.Based on the comprehensive evaluation of the yield,crude protein and relative feeding value of 15 silage maize varieties,it was concluded that the silage maize varieties such as Yayu Silage 8 and Beinong Silage208 were suitable for planting in the northern part of Shanxi Province.
