Cuttage seedling raising method for twigs of ilex chinensis Sims

Abstract

The invention discloses a cuttage seedling raising method for twigs of ilex chinensis Sims. According to the method, nursery stocks of ilex chinensis Sims are bred by utilizing the cuttage of the twigs of fruiting ilex chinensis Sims, the genetic characteristics of excellent mother plants of ilex chinensis Sims can be kept, and rapid breeding and cultivation of ilex chinensis Sims are achieved. The method comprises the steps of selection of mother trees, management, protection and cultivation of the mother trees, collection of cuttings, treatment of the cuttings, cuttage of the cuttings, infusion feeding for scions and management after cuttage, wherein the robust and disease-free fruiting nursery stocks are used as the mother trees, a cutting orchard is established, the twigs are cut for sprouting promotion, semi-lignified branches are selected as the cuttage scions, the cuttings are subjected to rooting-promotion and non-destructive treatment, the scions are supplied with nutrients invitro after cuttage, through tests, the rooting survival rate of the cuttings is 96%, and a large number of nursery stocks of ilex chinensis Sims can be quickly bred. The unique methods and structures of pretreatment of the scions and infusion feeding for the scions are critical, the problem of difficult breeding of seeds of ilex chinensis Sims is solved, the breeding speed is high, and the method is simple.
