摘要
采用播种和扦插育苗2种方式,开展了育苗试验,结果表明:在直播育苗中营养钵苗的株高、地径和主根长分别为5.30cm,0.20cm和5.40cm,优于裸根苗;2年生插穗培育的苗木成活率、新枝长、主根长和侧根数分别为70.0%,9.1cm,10.2cm和10,优于多年生插穗。
Sowing and cutting were applied for the reproduction of Potentilla arbuscula var. veitchii. The result showed that height, ground diameter and stem length of seedlings by sowing in containers were 5.30 era,0.20 cm and 5.40 cm respectively,superior to the bare root seedlings. Seedlings by two --year cut have better survival rate, new shoot, main root length and side root numbers, which are 70. 0%,9. 1cm,10.2 cm and10 respectively
