Method for raising seedlings of semi-lignified twigs of agilawood by cutting

Abstract

The invention discloses an agilawood semi-lignification twig cutting seedling raising method which comprises the following steps: (1) cultivating rootstocks: filling nutrient soil in a nutrient bag as a breeding matrix, and pruning when the seedling cultivation growth vigor height is 17-20cm higher than the ground; (2) preparing a mixed substrate: fully mixing peat soil, perlite and vermiculite according to a volume ratio of 1: 1: 1 to obtain the mixed substrate; (3) cutting slips: bundling every 30-50 treated cutting slips as a group, putting the cut parts at the lower ends of the bundled cutting slips into a rooting powder solution for 15-30 seconds, and then sequentially cutting the cutting slips into a substrate; (4) later-stage management and protection, wherein the cuttage environment is disinfected regularly. The method has the advantages that the method is used for raising seedlings through slope barrier cutting, the technical bottleneck that the agilawood trees are difficult to root is broken through, the agilawood trees start to root 30-35 days after cutting and can be transplanted 4-5 months later, the rooting time is effectively shortened, the cutting rooting rate and the transplanting survival rate of the agilawood trees are obviously increased, and the rooting quality of cutting slips is good.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation of agarwood, in particular to a method for seedling cultivation of semi-lignified twigs of agarwood. Background technique [0002] Agarwood, commonly known as agarwood, white wood incense, tooth incense tree, and daughter incense, is an arbor of the genus Agarwood in the family Daphneaceae, and it is an endangered tree species under national second-class protection. It is mainly distributed in Guangdong, Guangxi, Hainan, Taiwan, Yunnan and other provinces and regions. It is generally born below 400m above sea level, and can reach 1000m in Hainan. The wood of the Agarwood tree has aroma, and the resin secreted by old trunks or injured roots will form a brownish-yellow or light yellow solid after long-term deposition, which is a precious Chinese medicinal material - "Agarwood". Agarwood is a traditional precious Chinese herbal medicine and high-quality natural spices in my country. ...

Problems solved by technology

[0003] The seed setting rate of wild high-quality trees of Agarwood is low, and it is difficult to obtain a large number of high-quality seeds, and the seeds are not suitable for preservation, and are easy to lose vitality, which makes the process of sexual reproduction management and development of plantations slow and difficult.

Propagation by cuttings can solve the problems of insufficient seeds and large genetic differentiation. The research results show that Agarwood can be used for cuttings, but it faces the problems of low rooting rate and low quality of seedlings
