Problems solved by technology

However, the traditional cutting propagation has the following defects: 1) The environmental factors of cuttings are not easy to control; 2) The selection and classification of cuttings are not strict; 3) The rooting time of cuttings is 12-15 days, which is relatively slow; 4) The treatment method of cuttings is not suitable; 5) Cuttings are easily attacked by pathogens and cause rot
It is easy to waste patchouli branches and cutting resources or lead to low survival rate of cutting seedlings
On December 25, 2002, "China Journal of Traditional Chinese Medicine" published an article "Patchouli Propagation Method", but there are still limitations in cutting time, low survival rate, low quality of seedlings, waste of more branches and cuttings, etc. question
[0005] The State Intellectual Property Office also published a patent titled "Speedy rooting agent for woody plants". Cutting seedlings have poor disease resistance, poor disease prevention ability and slow growth rate

Embodiment 1

[0014] Embodiment 1: a kind of method of Patchouli fast rooting seedling cultivation, the method comprises the steps:

[0015] 1) Selection of ear-picking mother plants: In August 2013, a patchouli cutting seedling breeding experiment was carried out in the patchouli germplasm resource nursery of Hainan University, Haikou City. Firstly, the Patchouli plants with strong growth, good growth and no damage by diseases and insect pests are selected as the mother plants for ear picking; 0.2% Potassium Dihydrogen Phosphate solution was sprayed on the ear-picking mother plants once. Select semi-lignified twigs with 2 large leaves and 2 small leaves on the top as cuttings, cut the cuttings 8-10 cm, and cut the cuttings at 40-50 degrees and smooth. Then, immerse the cut hole with 70% thiophanate-methyl 800 times solution for 30 minutes to complete the sterilization, and then wash it with water. The preparation method of 70% thiophanate-methyl 800 times solution is as follows: Weigh 1g...

Embodiment 2

[0016] Embodiment 2: Compared with Embodiment 1, the difference of this embodiment is that: the cuttings are soaked in a solution of naphthalene acetic acid with a mass fraction of 0.03%, and taken out after 6 seconds; the steam temperature for sterilizing the matrix is ​​90°C. The actual effect is shown in Table 1.

Embodiment 3

[0017] Embodiment 3: Compared with Embodiment 1, the difference of this embodiment is that the cuttings are soaked in a solution of naphthalene acetic acid with a mass fraction of 0.02%, and taken out after 8 seconds; the steam temperature for sterilizing the matrix is ​​80°C. The actual effect is shown in Table 1.

Abstract

The invention relates to a semi-lignified twig cutting and fast root taking and seedling growing method for patchouli. The method comprises the key links of scion-seed stock plant selection, scion picking, root speeding treatment, cutting medium preparation, cutting and cutting post-management. According to the method, the cutting seedlings of the patchouli can root in advance, roots can be taken fast, the cutting survival rate can reach more than 99 percent, sprouting only needs 15 days, and cutting and seedling growing can be carried out all the year round. The method is easy to operate and popularize, a large number of high-quality patchouli seedlings can be cultured in a short time, and a good foundation is laid for the development of the patchouli industry.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for rapid rooting and seedling cultivation of patchouli. Background technique [0002] Patchouli [ Pogostemon cablin (Blanco) Benth.] is a herbaceous plant of the genus Patchouli of the Labiatae family. It is slightly warm in nature and pungent in taste. Patchouli is not only the main raw material of more than 30 kinds of Chinese patent medicines, but also an important raw material for medicine and light chemical industry with its extracted patchouli essential oil (used to prepare pills, ointments, pills, powders, cosmetics, and deodorants) and insecticides, etc.), the folks also use patchouli leaves to decoct and drink to avoid summer heat and dampness. Patchouli plants, as a natural taxonomic group, belong to tropical Asia. They rarely bloom in my country's production areas and have not been able to bear fruit. For more than a thousan...
