为国家Ⅰ级保护珍稀濒危植物异形玉叶金花的种群扩繁提供技术储备,选择1~2年生枝条,采用不同扦插方式对其进行研究。结果表明:异形玉叶金花扦插成活率为31.4%~68.2%,其中,遮阴网+塑料拱棚+黄心土基质处理的扦插成活率最高,为68.2%;0.5年生扦插苗木的苗高和地径生长量分别为30cm和0.4cm,1.5年生扦插苗的苗高和地径的生长量分别为87.9cm和0.58cm。扦插繁殖是异形玉叶金花可行的繁殖途径。
It provides technical reserve for the national grade Ⅰ population expansion of rare and endangered rare and endangered plant Goldenrod flowers, selects 1 to 2 year old branches and studies them with different cutting methods. The results showed that the survival rate of cuttings of Alnus mirabilis was 31.4% -68.2%, among which, the survival rate of the cuttings with shade net + plastic arch + yellow heart soil was the highest, which was 68.2%; the seedling height and diameter growth Respectively, 30cm and 0.4cm, 1.5 year-old cutting seedling height and diameter of the growth were 87.9cm and 0.58cm. Cutting propagation is a unique breeding jade leaves golden reproductive route.
