用1号ABT生根粉不同浓度的溶液对不同长度的柳杉穗条浸泡30min后,进行9个不同的处理试验,以查明穗条长度和ABT生根粉处理的浓度对培育柳杉扦插苗的影响。试验结果表明,长度20cm的1~2年生穗条用150×10-6的1号ABT生根粉溶液浸泡30min,3~4月份进行扦插育苗,苗木的苗高和成活率最佳,苗高可达46 7cm,苗木成活率可达86 7%。
Different ABT rooting powder solutions with different concentrations were used to soak cunninghamia lanceolata for 30min. Nine different treatment experiments were conducted to determine the effect of the length of the spike and the concentration of ABT rooting powder on the growth of Cryptomeria fortunei influences. The results showed that 1 ~ 2 year-old spikes of length 20cm were immersed in 150 × 10-6 ABT rooting powder solution for 30min, and cuttings were planted from March to April. The seedling height and survival rate were the best, Up to 46 7cm, seedling survival rate of 86 7%.
