| 摘 要： | 为选择适宜云南暖温带地区种植的青贮用玉米品种,在云南省曲靖市马龙区开展了22个玉米品种的品比试验。采用三重复随机区组设计,在蜡熟期对各供试品种的农艺性状、病虫害抗性、倒伏状况等指标进行了测定分析。结果表明:22个青贮玉米品种的单株叶鲜重、单株秆鲜重、单株鲜重、绿叶数、叶片数、茎粗与鲜株产量、干物质产量均存在显著或极显著的正相关(P<0.01或P<0.05);胜玉2号、曲辰11号、靖丰8号、青青300的鲜株产量、干物质产量均较高,且抗病、抗虫害能力强,无倒伏,适宜在云南暖温带及类似地区推广种植。

| Abstract: | In order to select corn varieties suitable for silage in the warm temperate zone of Yunnan,the planting variety comparison test of 22 corn varieties was carried out in Malong district of Qujing city.The experiment was designed with three replicates and random block group.The agronomic characters,pest and disease resistance,lodging condition and other indexes of the tested varieties were measured and analyzed at the wax-ripening stage.The result showed that the fresh leaf weight per plant,fresh stalk weight per plant,fresh weight per plant,number of green leaves,number of leaves,stem diameter and fresh plant yield and dry matter yield of silage corn were significantly positively correlated(P<0.01 or P<0.05).The fresh plant yield and dry matter yield of Shengyu 2,Quchen 11,Jingfeng 8 and Qingqing 300 were all higher,and they had strong resistance to diseases and pests and no lodging,which were suitable for planting in the warm temperate zone of Yunnan and similar areas. |
