摘要
为筛选出适宜黑龙江省种植的紫花苜蓿品种,对引自国内外的8个紫花苜蓿品种进行了物候期、返青率、株高以及产量等性状的比较试验。结果表明:不同苜蓿品种的生育时期有较明显的差异;返青率国内苜蓿好于国外苜蓿,其中国外苜蓿返青率第三、四年明显下降;农菁1号品种一次刈割株高高于其它品种;肇东品种二、三次刈割株高高于其它品种;肇东苜蓿产量最高,农菁1号与草原1号次之,敖汉最低,国外品种第三年后产量降低明显。综合评价认为,农菁1号、肇东苜蓿、草原1号及龙牧801紫花苜蓿品种的综合性状好、产量高且稳定,适宜黑龙江省地区推广种植。
In order to select suitable alfalfa cultivars of Medicago sativa for Heilongjiang province,8 alfalfa cultivars from home and abroad were taken to compare the phenological period,returning green rate,plant height and yield traits.The result showed that there were significant differences of growth stages among different alfalfa cultivars;The returning green rate of alfalfa from domestic were better than foreign alfalfa cultivars,whose reterning green rate decreased evidently in the third and fourth year;Mowing height of Nongjing No.1 was higher than that of other cultivars,the second or third mowing height of Zhaodong were higher than those of other cultivars;The yield of Zhaodong was the highest,followed by Nongjing No.1 and Caoyuang No.1,Aohan was the lowest,the yield of foreign cultivars were decreased evidently in the third year.It comprehensive evaluated that Nongjing No.1,Zhaodong,Caoyuan No.1 and Longmu 801 owned good comprehensive properties,high and stable yield,they were suitable for planting in Heilongjiang province.
