刺梨扦插繁育技术初探

Primary Discussion on Cutting Propagation Technology of Rosa roxburghii

[目的]探讨刺梨扦插繁育技术,扩大刺梨人工栽植面积。[方法]研究不同植物激素、入土深度和扦插方式对扦插成活率、发枝数、苗高的影响。[结果]以ABT生根剂600 mg/kg处理成活率达83.3%,平均发枝数4条,苗高26.8 cm;扦插入土深度5~6 cm处理成活率76.5%,发枝数（3条）和苗高（28.3 cm）均高于入土深度7~8、3~4 cm处理;60°斜插成活率77.8%。[结论]以ABT生根剂600mg/kg、扦插入土深度5~6 cm、60°斜插促根效果好,成活率较高。

[Objective] The aim was to discuss cutting propagation technology and expand artificial cultivation area of Rosa roxburghii.[Method]Effects of different plant hormone,depth and cutting ways on survival rate,number of branches and seedling height were studied.[Result]The survival rate was 83.3%,average branch number was 4 and seedling height was 26.8 cm by applying 600 mg/kg ABT rooting agent;the survival rate was 76.5%,branch number was 3 and seedling height was 28.3 cm when cutting depth was 5-6 cm;the survival rate was 77.8% under 60° oblique cutting.[Conclusion]600 mg / kg ABT rooting agent,soil depth 5-6 cm and 60° oblique cutting are good for rooting and have higher survival rate.
