摘    要:采用不同的生根剂、扦插环境及扦插时间对鹿角杜鹃进行扦插繁殖对比试验,结果表明:鹿角杜鹃生根较慢,扦插80 d后才能生根;在不同的季节和以不同的生根剂处理穗条以及不同的生境,其成活率差异明显。7月份扦插的鹿角杜鹃平均成活率达85%,最高达90%;3种不同的生根剂处理,浓度150 mg/L的双吉尔(GGR)处理的插穗扦插成活率明显高于其他几种,其平均成活率达85%,最高达90%。95%的遮阳网下鹿角杜鹃扦插成活率明显高于森林郁闭度达80%的林下,其平均成活率达85%,最高达90%。

关 键 词:园林植物  鹿角杜鹃  扦插试验

Abstract:The effects of rooting agent,cutting environment and cutting time on cutting propagation of Rhodendron latoucheae were compared.The results showed that,after 80d,the cuttings of Rhodendron latoucheae began to rooting.The effects of different rooting agent,different cutting environment and different cutting time on the survival rate of cuttings were significantly discrepant.When the cutting time was in July,the average survival rate of cuttings was 85% and the highest survival rate was 90%.As far as cuttings treated with three rooting agent were concerned,when the concentration of GGR rooting agent was 150mg/L,the average survival rate of cuttings was 85% and the highest survival rate was 90%,which was higher than those of cuttings treated with other rooting agent.Under shade net with 95% shade,the average survival rate of cuttings was 85% and the highest survival rate was 90%,which was significantly higher than those of cuttings that were under forest with canopy density of 80%.
Keywords:landscape plant  Rhodendron latoucheae  cutting test
