Problems solved by technology

The seedling cultivation methods mainly include asexual cutting cultivation, etc., but the initial spikes of asexual cutting cultivation have no root system and there are wounds, which in turn makes the callus formation of cutting seedlings slow, rooting late and the survival rate is low, which in turn makes the cultivated Cochin chinensis Sandalwood survival rate is low

Embodiment 1

[0079] The present embodiment provides a kind of cutting seedling raising method of Dalbergia cochinchinensis, comprising:

[0080] First, build a simple greenhouse:

[0081] Purchase materials such as curved arch galvanized pipes with a diameter of 4 points and a length of 6m each for building a simple greenhouse, and galvanized pipes with a diameter of 6 points for columns and a length of 1.8m. On both sides of the greenhouse in the long direction, the pillars are 1.4m above the ground, and the distance between each pillar is 1.2m. Insert the curved galvanized pipe directly into the galvanized pipe of the pillar, and then fasten the fasteners to fix it. The length is 15-16m and the width is 15-16m. A simple greenhouse with a height of 5m and an arch height of 2.5m. The greenhouse can not be too long, if it is too long, it will affect the ventilation and heat dissipation effect. At the same time, the automatic spraying water pipe facilities are installed in the greenhouse t...

Embodiment 2- Embodiment 4

[0104] The operation of the cutting and seedling raising method of Dalbergia cochinchinensis that embodiment 2-embodiment 4 provides is basically consistent with embodiment 1, and difference is that the concentration of the rooting powder solution and the soaking time of soaking treatment ear bar are different, specifically refer to the following table:

[0105]

[0106] It can be seen from the above table that soaking the cuttings of the cuttings with 300ppm solution of Shuangjier GGR for 1 hour has the best effect, the average survival rate of the cuttings is up to 94.87%, and the average seedling rate is 89.53%; The effect of cuttings is next, with an average survival rate of 82.46%, a seedling rate of 77.19%, and a lower rate of unrooted plants. These two hormone concentrations can be applied in production.

Embodiment 5- Embodiment 6

[0108] The operation of the cutting seedling raising method of Dalbergia cochinchinensis provided by embodiment 5 and embodiment 6 is basically consistent with embodiment 4, the difference is that the cutting time is different, embodiment 1-4 is cutting in March 2018, embodiment 5 and 6 are 2016 Cuttings from November 2017 to March 2017, see the table below for details

Abstract

The invention relates to the technical field of cutting seedling raising of dalbergia cochinchinensis, in particular to a cutting seedling-raising method of dalbergia cochinchinensis. The cutting seedling-raising method of dalbergia cochinchinensis comprises the following steps: in a greenhouse, building arch sheds on cuttings of dalbergia cochinchinensis subjected to cutting, covering the cuttings of dalbergia cochinchinensis subjected to cutting with plastic films, then controlling the temperature and the humidity in the arch sheds by spraying water in the arch sheds and cutting holes out ofthe plastic films for multiple times to make the humidity in the arch sheds remain at 75% or above and to make the temperature remain at 35 DEG C or below, and after the cut cuttings sprout for 2-3 times and leaves turn green, removing the films. By means of the method, callus forming and rooting of the cuttings can be accelerated, so that the survival rate of cutting seedlings is improved.

Description

technical field [0001] The invention relates to the technical field of cutting and growing seedlings of Dalbergia cochinchinensis, in particular to a method for growing seedlings of Dalbergia cochinchinensis by cuttings. Background technique [0002] Dalbergia cochinchinensis (scientific name: Dalbergia cochinchinensis Pierreex Laness) is a leguminous Dalbergia plant, a large deciduous tree (evergreen tree in some areas of Vietnam and Thailand), the height is generally 8-30m, the trunk diameter can reach 60-120cm, sometimes There are several trunks and branches. The bark is smooth and hard, light yellow to taupe, scaly. The seedling cultivation methods mainly include asexual cutting cultivation, etc., but the initial spikes of asexual cutting cultivation have no root system and there are wounds, which in turn makes the callus formation of cutting seedlings slow, rooting late and the survival rate is low, which in turn makes the cultivated Cochin chinensis Sandalwood has a ...
