供试的17个燕麦品种在高寒牧区生长期约100d,但种子不能成熟,均属中、晚熟型;其中永久444、P67、加拿大和永久404燕麦的生长速度较快,分别为2.70、2.36、2.22和2.02cm/d。加拿大燕麦的绝对生长率最高,达29.59g/m2.d,永久1号的相对生长率最高,为0.072g/g.d。P20的鲜、干草产量明显高于其他品种,分别达到50.55和16.18t/hm2,永久440的鲜、干草产量极低,仅为17.22t/hm2和5.51t/hm2。P67、永久444、066和罗马尼亚燕麦的茎叶比较小,叶量丰富、适口性好且营养成分含量高,品质较好。综合分析结果表明,P20、加拿大、P67和永久444燕麦是天祝金强河地区建设高产、优质燕麦人工草地的理想品种。
供試的17箇燕麥品種在高寒牧區生長期約100d,但種子不能成熟,均屬中、晚熟型;其中永久444、P67、加拿大和永久404燕麥的生長速度較快,分彆為2.70、2.36、2.22和2.02cm/d。加拿大燕麥的絕對生長率最高,達29.59g/m2.d,永久1號的相對生長率最高,為0.072g/g.d。P20的鮮、榦草產量明顯高于其他品種,分彆達到50.55和16.18t/hm2,永久440的鮮、榦草產量極低,僅為17.22t/hm2和5.51t/hm2。P67、永久444、066和囉馬尼亞燕麥的莖葉比較小,葉量豐富、適口性好且營養成分含量高,品質較好。綜閤分析結果錶明,P20、加拿大、P67和永久444燕麥是天祝金彊河地區建設高產、優質燕麥人工草地的理想品種。

Comparison study on oat varieties was conducted at Tianzhu Alpine Grassland Research Station of Jingqianghe Area,China.The results showed that in Jingqianghe area,the growth period of all the varieties of oat(Avena sativa) was nearly 100d,all of them were mid-term mature or late mature varieties; Among them,No.444 Yongjiu,P67,Canadian Cultivator and No.404 Yongjiu grew rapidly,with 2.70cm/d、2.36cm/d、2.22cm/d and 2.02cm/d growth speed respectively; The variety of Canadian Cultivated had the highest absolute growth rate(AGR) and the variety of No.1 Yongjiu possessed the highest relative growth rate(RGR); The variety of P20 had the highest forage yield,with 50.55 and 16.18t/hm2 of the fresh matter(FM) and dry matter(DM),while the variety of No.440 Yongjiu Oat possessed the lowest forage yield,with 17.22t/hm2 FM and 5.51t/hm2 DM: Compared with other Varieties,P67,No.444 Yongjiu,No.066 and Romania had lower stem/leaf ratio(S/L),more leaves and better palatability,their qualities were better,they were the better varieties to get high quality grassland.When combined all the measurements,it can be concluded that P20,CC,P67 and No.444 were the target varieties used for artificial oat grassland with high productivity and good quality in Jingqianghe area,the Tianzhu alpine region of China.
