Abstract: In order to select the silage corn (Zea mays L.) hybrids suitable for planting in the northern part of Shanxi Province,the agronomic characteristics of 16 hybrid corn and the fermentation quality of silage prepared after castration were measured. The results showed that in agronomic characteristics,DJJ 26 had the highest plant height and ear height,but its stem diameter was the thinner. The green-leaf number ranked in the top three is TY168,QS 30 and GK516. For yields,DF26 had the highest yield. For ensiling characteristics,except for DH679,TY511,all hybrids were below 4.20 for pH values. The significantly positive correlation was found between fresh grass yield and stem diameter,green-leaf number,stem weight,ear weight,leaf weight. The Lactic acid content of whole plant corn silage was positively correlated with green-leaf number. Therefore,the corn hybrids with thick stems,more green leaves and good panicle traits should be selected for silage use. The JD65 and TY168,GK516 and QS30 have good growth and fermentation performance,thereby,could be selected for silage corn in the northern part of Shanxi Province.

Key words: Whole plant corn, Hybrids, Agronomic characteristics, Silage quality

摘要: 为选出适宜山西省北部地区种植的青贮玉米(Zea mays L.)品种,对16个玉米品种的农艺性状及其全株收割后调制成的青贮饲料的青贮品质进行了比较和相关性分析。结果表明,在农艺性状方面,‘大京九26’的株高和穗位均最高,茎粗较细;绿叶数排在前三位的为‘屯玉168’、‘强盛青贮30’和‘京科青贮516’;在产量方面,‘大丰26’的鲜草产量最高;调制成青贮饲料后,除‘登海679’、‘太玉511’,其余品种的pH值均小于4.20,‘先玉1225’的淀粉含量最高;鲜草产量与茎粗、绿叶数、茎重、穗重和叶重成极显著正相关,青贮饲料的乳酸含量与绿叶数成显著正相关。综上,种植青贮玉米时,可选择茎秆粗壮,绿叶数多、穗位低的品种;粮饲兼用品种‘晋单65’、‘屯玉168’,青贮专用品种‘京科青贮516’、‘强盛青贮30’的综合表现较好,可作为青贮玉米品种在山西省北部地区推广种植。
