摘要
为筛选出适宜在兴安盟地区种植的燕麦饲草品种,对25个燕麦品种的物候期、不同刈割时期草产量进行品种比较试验。结果表明,燕麦品种生育期为70~87 d,孕穗期鲜草产量为18.3~68.2 t·hm2、干草产量为2.9~8.0 t·hm^(-2);抽穗期鲜草产量为27.6~72.4 t·hm^(-2)、干草产量为4.8~8.1 t·hm^(-2);开花期鲜草产量为38.8~76.2 t·hm^(-2)、干草产量为6.7~14.8 t·hm^(-2);乳熟期鲜草产量为32.4~87.0 t·hm^(-2)、干草产量范围为7.4~22.2 t·hm^(-2),品种之间存在显著差异(P<0.05)。综合分析试验结果得出,孕穗期和抽穗期收获干草可以种植坝莜3号,开花期收获干草可以种植远杂1号和坝莜18号,乳熟期收获干草可以种植张莜13号、定燕2号和GL381。
In order to select forage oat varieties adapted for cultivation in Hinggan League,forage yields of 25 oat varieties at different phenological stages and cutting stages were compared in a field experiment.The results showed that the phenological periods of oat varieties ranged 70-87 d;the fresh yields and hay yields ranged 18.3-68.2 t·hm^(−2) and 2.9-8.0 t·hm^(−2) at booting stage,27.6-72.4 t·hm^(−2) and 4.8-8.1 t·hm^(−2) at heading stage,38.8-76.2 t·hm^(−2) and 6.7-14.8 t·hm^(−2) at flowering stage,32.4-87.0 t·hm^(−2) and 7.4-22.2 t·hm^(−2) at milk ripening stage,respectively.Significant yield differences were found among varieties(P<0.05).Comprehensive analysis showed that variety Bayou 3 is suitable for hay harvested at booting and heading stages;varieties Yuanza 1 and Bayou 18 are suitable for hay harvested at flowering stage;and varieties Zhangyou 13,Dingyan 2 and GL381 are suitable for hay harvested at milk ripening stage.
