摘要
在海北高寒地区对6种良种燕麦进行引种比较试验,结果表明,在海拔3100m地区,青海444和87-444两个品种种子完全能成熟,全生育天数为126d,其他品种由于气温低(年均温-0.1℃),生长季短,种子不能完全成熟,但籽实产量和产草量均极显著高于当地黄燕麦。青引2号在海拔2800m以下种植,种子完全能成熟,籽实产量平均达3336.4kg/hm2,生育期为120 d左右,可在当地进行种子繁殖。
Comparative trial of 6kinds of fine oats were carried out in Haibei alpine area . The results showed that two kinds of seeds of Qinghai 444 and 87 -444 could complete ripeness , all days of growth were 126days when altitude was 3100m.. Because air temperature was low（ average temperature -0. 1℃ ）, other kinds of breeds couldn＇t complete ripeness, but yield of seeds and yield of grass were obviously high then local oats. Seeds of Qingyin 12 could complete ripeness when altitude was below 2800, yield of seeds reached to 3336. 4kg/hm^2, growth period was 120days, seeds could be reproduced in local area.
