Purple-leaf plum cutting seedling nursing method

Abstract

The invention discloses a purple-leaf plum cutting seedling nursing method. The method comprises the steps of nursery selection, seed bar picking, cutting slip cutting, cuttage and post-cuttage management, wherein the post-cuttage management comprises moisture management, temperature and humidity regulation and fertilization. After cutting of cutting slips, ABT rooting powder is dipped, so that the effects of disinfecting wounds and preventing a wound from being rotten are achieved, and healing and rooting of wounds of the cutting slips can be promoted. By adopting a breeding method disclosed by the invention, the survival rate can be increased and can be up to over 85 percent, and annual outplanting can be realized.
