中华红叶杨扦插育苗技术研究

Research on the Cutting and Seedling of Populus deltoids cv.Zhong hua hongye

分析了GGR浓度、多菌灵浓度、扦插时间、扦插基质和枝条性质等对中华红叶杨扦插育苗的影响,结果表明除多菌灵浓度对扦插成活率没有显著影响外,其他四种方式对中华红叶杨扦插均有显著影响。选择上年秋枝和当年夏枝作为扦插育苗,以GGR100mg/kg浸泡2h,以纯黄心土作为扦插基质,于3月中旬或9月底进行扦插,其效果最佳。

By means of the single factor analysis, the effects of consistency of GGR, the carbendazim of significant difference and cutting time and the character of branch on cutting were studied. The results showed that the fourth way were all influenced the cutting seedlings of Populus deltoids cv. Zhong hua hongye except Carbendazim. The best effects in seedling was using autumn branch of last year or summer branch this year as cutting seedling, immersing in GGR100mg/kg 2hours and using pure inner yellow mud as cutting medium, and cutting seedling in middle of March or end of September.
