Phoebe bournei cutting propagation method

Abstract

The invention discloses a phoebe bournei cutting propagation method. The method includes the steps of stock plant cultivation, cut truck sprout promotion, cutting selection and cuttage, stock plant management and cutting seedling management. The method is characterized in that fine clone nursery stocks are planted in seedling cultivating devices with substrates so as to cultivate stock plants, seedling trucks are cut from the base portions of the stock plants, hormone is sprayed and applied to the seedling trucks for promoting sprouts, selected high-quality cuttings are arranged in a sunshelter through cutting after being processed through rooting accelerators, a mixed nutrient solution is sprayed and applied, and then phoebe bournei fine clone cutting seedlings are obtained. By means of the method, expected characters of phoebe bournei select trees can be completely kept, the capacity of phoebe bournei root systems for absorbing nutrients can be improved, high-quality phoebe bournei branches are cultivated to serve as cuttings, the propagation coefficient and the cutting survival rate are both high, cost is low, popularization is easy, an effective and reliable method is provided for keeping phoebe bournei germ plasm resources and promoting fine clone seedlings, and the method has high social benefits and economical benefits.

Description

technical field [0001] The invention belongs to the technical field of plant asexual propagation, and relates to a cutting propagation method of nannus. Background technique [0002] Phoebe bournei (Phoebe bournei) is an evergreen tree of the genus Phoebe in Lauraceae. It is a second-class endangered plant in my country. It is only scattered in western Hubei, southern Zhejiang, Fujian, Jiangxi, Hunan, Guangdong, northern Guangxi and eastern Guizhou in my country. 200-1 000 m in mountainous evergreen broad-leaved forests. Minnan is a unique landscaping tree species and an excellent and precious timber tree species in my country. However, due to the lack of natural forests and low seed yield, it cannot meet the needs of artificial afforestation for seedlings. And through asexual reproduction, it can solve the problems of insufficient seeds and large genetic differentiation, and open up a new way for the preservation, development and utilization of Minnan resources.
