摘　　要：通过对四川省凉山光叶紫花苕新品系在高寒地区冬季生长及耐牧性测定分析,结果表明:一是其抗寒性强,最冷季枝条长度平均日生长量0.44-0.63cm,最冷期枝条重量日相对增长量0.0323g,667m2的日生物生长量9.55kg,茎叶比1:2,叶量丰富;二是放牧后再生能力强,其在最冷季啃食放牧后再生测定,每株平均啃食枝条数6.54个,15 d后萌发枝条平均8.80个,比放牧前多2.26个,平均萌发枝条5.62 cm,平均日生长量0.37 cm,表明紫花苕新品系具有可放牧性特性。The winter growth and grazing tolerance of the new strain of Vicia villosa Roth var.glabrescens cv.Liangshan were tested in the alpine region. The results showed that the branch height increased by 0.44-0.63 cm/d in the coldest season and the average relative daily weight increased by 0.032 3g/d, the daily biomass by 143.25 kg per hectare, the stem-leaf ratio was 1：2; in the coldest season, 6.54 branches had been eaten per individual plant averagely after grazing, 8.80 branches regenerated after 15 days,the new branches could grow 5.62 cm averagely and 0.37 cm per day. It showed that the regeneration ability was very strong.
