通过对参试的15个紫花苜蓿品种的生态抗寒、生物学特性、生产性能及干草产量、经济效益的综合评价分析,筛选出适合哈尔滨地区种植的紫花苜蓿品种有:龙牧801、敖汉、飞马、皇冠、CuA122、CuA431、胖多.但是由于该地区寒冷的气候造成保苗率下降,严重影响干草产量,特别是国外引进的品种干草减产更为明显.所以在该地区种植这些品种,周期不宜过长,一般不超过3年,以保证较高的产量和良好的经济效益.表5,参4.

On the basis of the comparison of anticold, biological characteristics, production and hay yield, economic benefit, the adaptability of 15 introduced and local alfalfa cultivars were studied by using synthesis analysis. The results showed that Longmu801, Aohan, Grandeur, Phabulous, CuA122,CuA431 ,Pondus were adaptived.The seedling survival was lower and hay yield was decreased for cold climate, specialy for overseas breeds.The results identified that growing period were not long and not exceed 3 years planting in this area.
