摘要
为筛选适宜云南省亚热带山区秋季种植的饲用燕麦品种,在曲靖市引入枪手、魁北克、贝勒、福星、定莜8号、定莜9号、定莜11号等14个饲用燕麦品种,通过对其农艺性状以及营养品质进行比较分析,应用灰色关联度法综合评价各品种的生产性能。结果表明,定莜8号、定燕2号、定燕4号、太阳神的株高较高,株高在70~80cm之间;鲜草产量较多的是贝勒、福星、定燕2号、太阳神,其中,贝勒鲜草产量最高,为12.69t/hm^(2);干草产量较多的品种为福星、定燕2号,其产量分别为6.05t/hm^(2)与6.04t/hm^(2);定燕2号单株鲜重与干重最高,分别为5.07g与2.84g;定莜9号分蘖数最高,分蘖数平均为9.5个,其次是福星分蘖数较高,平均为8个;粗蛋白含量较高的为枪手、定莜9号、定莜11号、定燕2号、定燕4号和太阳神,含量在9.05%~10.53%之间;粗脂肪含量最高的为福星,为5.55%,其次为定燕3号,为5.30%;粗纤维含量较低的为福星、定燕3号、楷模和艾博,含量在3.83%~5.02%之间;粗灰分含量较低的为魁北克、定燕3号和楷模,含量在2.60%~3.02%之间。综合各项指标得出,在云南亚热带山区旱作条件下饲用燕麦秋播综合表现较好的品种有定燕2号、福星、定燕4号,贝勒,这4个燕麦品种具有较佳的生产性能。
In order to screen the suitable varieties of forage oats for autumn planting in the subtropical mountainous areas of Yunnan province,14 forage oat varieties,including Shooter,Quebec,Belle,Fuxing,Dingyou No.8,Dingyou No.9,Dingyou No.11,etc.,were introduced in Qujing city.Through comparative analysis of their agronomic traits and nutritional quality,the grey correlation method was used to comprehensively evaluate the production performance of each variety.The results showed that Dingyou No.8,Dingyan No.2,Dingyan No.4 and Sun God had relatively high plant heights,with plant heights ranging from 70 to 80 cm;Belle,Fuxing,Dingyan No.2 and Sun God had relatively high fresh grass yields,among which Belle had the highest fresh grass yield of 12.69 t/hm^(2);Fuxing and Dingyan No.2 had relatively high dry grass yields,which were 6.05 t/hm^(2) and 6.04 t/hm^(2) respectively;Dingyan No.2 had the highest fresh weight and dry weight per plant,which were 5.07 g and 2.84 g respectively;Dingyou No.9 had the highest tiller number,with an average of 9.5 tillers,followed by Fuxing with a relatively high tiller number,with an average of 8 tillers;Shooter,Dingyou No.9,Dingyou No.11,Dingyan No.2,Dingyan No.4 and Sun God had relatively high crude protein contents,with contents ranging from 9.05%to 10.53%;Fuxing had the highest crude fat content of 5.55%,followed by Dingyan No.3 with a content of 5.30%;Fuxing,Dingyan No.3,Kai Mo and Ai Bo had relatively low crude fiber contents,with contents ranging from 3.83%to 5.02%;Quebec,Dingyan No.3 and Kai Mo had relatively low crude ash contents,with contents ranging from 2.60%to 3.02%.Based on the comprehensive consideration of various indicators,it was concluded that Dingyan No.2,Fuxing,Dingyan No.4 and Belle had better comprehensive performance in autumn sowing of forage oats under dry-farming conditions in the subtropical mountainous areas of Yunnan,and these four oat varieties had better production performance.
