简述黄寿丹的四种繁殖栽培技术

       黄寿丹，别名老来青、还少丹、为紫茉莉科植物黄细心的根。多年生草本，全株无毛或被疏毛。根肉质，长锥形，外表灰黄色或淡紫色。黄寿丹可用于食品天然防腐剂或化妆品, 又是重要的油料作物、观赏植物和水土保持植物，在繁殖黄寿丹的方法上，黄寿丹通常采用四种常规的繁殖栽培技术，下面小编就为大家介绍一下这四种常规的繁殖栽培技术：

黄寿丹繁殖栽培技术　
　

（一）、选地整地：
　　

   黄寿丹应选择在交通相对便利，1500米以内没有排放有害气体和灰尘的工矿企业，生态条件良好，坡度在32度以内，土层深厚，腐殖质含量丰富，土壤透气性能好，土壤呈微酸性至中性。背风向阳的退耕还林地及山坡荒地。施肥应在栽植前15天进行。坡度在25度不需整为梯田，可在清除对黄寿丹生长有影响的较大杂灌后(其他不影响黄寿丹生长的小灌丛及杂草，保持原貌，防止造成水土流失)，直接按1.5米×2米或1.2米×1.5米田地挖50厘米×50厘米栽植穴，栽植穴呈“品”字型排列，将肥料按梯田内施肥方法施入穴内。并将栽植穴外整理为外高内低的半圆形鱼鳞坑状。
