在灌溉和旱作两种水分条件下,选择10个燕麦品种,测定其在抽穗期、灌浆期、乳熟期的鲜草产量、干草产量,以及成熟期籽粒产量及其构成因素等,进而对其抗旱生态适应性进行评价.结果表明:灌溉处理下燕麦鲜、干草产量分别较干旱处理增加了13.3%、13.43%;坝燕4号品种干重和鲜重均高于其他品种(P<0.05);在干旱条件下,坝燕4号籽粒产量最高,白燕7号、内燕5号次之,且与其他品种间差异显著(P<0.05);在灌溉条件下,白燕7号品种的籽粒产量显著高于其他品种(P<0.05).从籽粒产量角度考虑,蒙燕1号、内燕5号、坝燕4号和白燕7号品种的抗旱性指数均达到“极强”水平;从生物产量角度分析,保罗和燕科1号抗旱性指数达到“极强”水平;坝燕4号、蒙燕1号等品种达到“强”水平.因此,综合产量及抗旱性指数评价结果,蒙燕1号、白燕7号和坝燕4号等3个品种具有较强的抗旱性和丰产性,适合作为内蒙古中西部地区饲用燕麦品种.
在灌溉和旱作兩種水分條件下,選擇10箇燕麥品種,測定其在抽穗期、灌漿期、乳熟期的鮮草產量、榦草產量,以及成熟期籽粒產量及其構成因素等,進而對其抗旱生態適應性進行評價.結果錶明:灌溉處理下燕麥鮮、榦草產量分彆較榦旱處理增加瞭13.3%、13.43%;壩燕4號品種榦重和鮮重均高于其他品種(P<0.05);在榦旱條件下,壩燕4號籽粒產量最高,白燕7號、內燕5號次之,且與其他品種間差異顯著(P<0.05);在灌溉條件下,白燕7號品種的籽粒產量顯著高于其他品種(P<0.05).從籽粒產量角度攷慮,矇燕1號、內燕5號、壩燕4號和白燕7號品種的抗旱性指數均達到“極彊”水平;從生物產量角度分析,保囉和燕科1號抗旱性指數達到“極彊”水平;壩燕4號、矇燕1號等品種達到“彊”水平.因此,綜閤產量及抗旱性指數評價結果,矇燕1號、白燕7號和壩燕4號等3箇品種具有較彊的抗旱性和豐產性,適閤作為內矇古中西部地區飼用燕麥品種.

In order to provide a theoretical basis for the selection of drought resistance oat cultivar,the fresh grass yield,hay yield (including three period yield such as heading stage,grain filling and mature period),grain yield and yield formation of the 10 oat cultivars were measured under irrigated and rainfed conditions in this experiment.The results showed that under irrigation treatments,the fresh yield and hey yield significantly increased by 13.3% and 13.43% respectively compared with those of rainfed treat—ments;the dry weight and fresh weight of the Bayan No.4 were higher than that of the other oat cultivars (P<0.05).Under rainfed conditions,Bayan No.4 had the highest grain yield,Baiyan No.7 and Neiyan No.5 took the second and third place (P<0.05);under irrigation treatments,Baiyan No.7 had the highest grain yield and significantly higher than that of the other 9 cultivars (P<0.05).In the view of grain yield, the drought resistance index of the Mengyan No.1 ,Neiyan No.5 ,Bayan No.4 and Baiyan No.7 were reach to pole—strength level;Analysis from biological yield,the drought resistance index of the Paul and Yanke No.1 were reach to pole—strength level,and Bayan No.4 and Mengyan No.1 were reach to strong level. Therefore,Mengyan No.1 ,Baiyan No.7 and Bayan No.4 due to their strong drought resistance and high yield performance were suitable for being planted in dry land of mid—west of Inner Mongolia.
