摘要
观测15个燕麦(Avena sativa)品种的产量和营养品质等指标,研究不同生育期对不同燕麦品种全株产量和营养价值的影响,为鄂尔多斯地区引进高产优质的燕麦品种提供科学参考依据.结果表明:1)在灌浆期、乳熟期和蜡熟期干草产量最高的品种分别是'爱沃256''领袖'和'黄燕麦';2)粗蛋白含量在灌浆期、乳熟期和蜡熟期最高的品种分别是'爱沃256''青引2号'和'甜燕麦';3)粗灰分含量在灌浆期、乳熟期和蜡熟期最低的品种分别是'青引1号''白燕7号'和'黄燕麦';4)'青引2号'的中性洗涤纤维含量在灌浆期最低,蜡熟期和乳熟期最低的品种均是'白燕7号';5)在灌浆期、乳熟期、蜡熟期酸性洗涤纤维含量最低的品种均是'白燕7号';6)随着生育期的推移,'白燕7号'的干草产量先降低后增加,粗蛋白含量无显著变化,酸性洗涤纤维和中性洗涤纤维含量显著下降.综合分析得出,'白燕7号'可作为鄂尔多斯地区高产优质的燕麦品种进行推广种植,其最适刈割期为蜡熟期.
Abstract
In the present study,the effects of different growth periods on the yield and nutritional value of 15 oat varieties(Avena sativa)were investigated.The results provide a scientific reference for the introduction of high-yield and high-quality oat varieties in the Ordos region in China.The main results were as follows:1)the varieties with the highest hay yield in the grain filling stage,milky stage,and waxy stage were'Everleaf 256''Souris''Yellow Oat',respectively;2)the varieties with the highest crude protein content in the grain filling stage,milky stage,and waxy stage were'Everleaf 256''Qingyin No.2''Sweet Oat',respectively;3)the varieties with the lowest crude ash content in the grain filling stage,milky stage,and waxy stage were'Qingyin No.l''Baiyan No.7''Yellow Oat',respectively;4)the neutral detergent fiber content of'Qingyin No.2'was the lowest in the grain filling stage,and the variety with the lowest neutral detergent fiber content in the milky stage and waxy stage was'Baiyan No.7';5)the variety with the lowest acid detergent fiber content in the grain filling stage,milky stage,and waxy stage was'Baiyan No.7';6)as the growth period increased,the hay yield of'Baiyan No.7'decreased first and then increased,and the crude protein content did not change significantly,while the acid detergent fiber and neutral detergent fiber content decreased significantly.These results indicate that'Baiyan No.7',a high-yield and high-quality oat variety whose most suitable cutting period is the waxy stage,shows potential as a crop in the Ordos Region.
