通过博落回室内根段繁殖试验,探究博落回根段直径、育苗时间、温度等因素对育苗发芽率及育苗生长情况的影响,结果表明:(1)博落回根段育苗可在春夏进行,根段长4cm,根径1.5cm以下根段发芽成苗率平均76.33%,根径1.5—2cm根段发芽成苗率平均80%-83.33%,根径2—4cm根段发芽成苗率平均86.67%;(2)博落回植物根径大小对秧苗素质具有较大影响,2-4cm的根段培育苗的株高6.86cm、茎粗0.41cm和叶片数9片,均优越根径2cm以下的培育苗;(3)在18℃以上的土温条件下,根段发芽成苗的开始时间为栽植后的5-8天,持续的时间22天左右。
The results showed that: (1) Breeding of Rehmannia glutinosa Libosch can take place in the spring Xia conduct, the root section length 4cm, root diameter of 1.5cm roots germination seedling rate average 76.33%, root diameter 1.5-2cm root germination rate of 80% -83.33%, roots 2-4cm root germination The average seedling rate was 86.67%. (2) The root diameter of Botanic Reciprocal Plant had a significant effect on the quality of the seedling. The plant height of 6.8-4cm, 0.41cm stem diameter and 9 leaves were superior Root diameter of 2cm below the nursery seedlings; (3) at 18 ℃ above the soil temperature conditions, the root germination seedlings start time 5-8 days after planting for a duration of about 22 days.
