Embodiment 1

[0011] Embodiment 1, a kind of rooting induction method of hydroponic black orchid

[0012] Rooting induction method of the present invention is carried out according to the following steps:

[0013] (1) Treating the bare-root seedlings of Molanca orchids: select the bare-rooted Molan orchids seedlings with a height of 20-30 cm, strong growth, and no pests and diseases as test materials. Cut off the old and damaged roots on the bare-rooted seedlings of Molan, and use 1.25% MnKO 4 Soak the lower part of the pseudobulb in the solution for 10-15 minutes to disinfect.

[0014] (2) Prepare auxin solution: use 95% alcohol to dissolve the auxin solid, and prepare an auxin solution with a concentration of 1-10mg / L.

[0015] (3) Induce rooting of bare-rooted seedlings: Insert the bare-rooted seedlings vertically into containers containing various concentrations of auxin or purified water. When the roots of the bare-rooted seedlings are soaked in the solution, there is a bare part for...

Embodiment 2

[0046] Embodiment 2, the influence of different nutrient solutions on the growth of hydroponics Molan plant

[0047] On the basis of screening the auxin treatment, Japanese Yamazaki formula nutrient solution, Hoagland standard nutrient solution, Hoagland and Arnon formula nutrient solution were used to cultivate Molan plants.

[0048] The specific steps are the same as in Example 1, except that different nutrient solutions are used. Take purified water as a control, and the temperature and humidity are the same as before.

[0049] Experimental group 21: Japanese Yamazaki formula nutrient solution

[0050] Experimental group 22: Hoagland standard nutrient solution

[0051] Experimental group 23: 1 / 2 Hoagland and Arnon formula nutrient solution

[0052] Experimental group 24: 1 / 2 Hoagland standard nutrient solution, 1 / 3 mixture of Hoagland and Arnon formula nutrient solution, the volume ratio of the two is 1:2

[0053] Control group 3: purified water

[0054] Change the nut...

Embodiment 3

[0058] Embodiment 3, the matching use of best auxin and best nutrient solution

[0059] In this example, the auxin used is a mixture of indole butyric acid, naphthalene acetic acid and indole acetic acid, in which the concentrations of indole butyric acid, naphthalene acetic acid and indole acetic acid are all 5.0 mg / L, mixed at a volume ratio of 1:1:1 Obtained; the nutrient solution used is a mixture of 1 / 2 Hoagland standard nutrient solution, 1 / 3 Hoagland and Arnon formula nutrient solution, obtained by mixing at a volume ratio of 1:2.

[0060] The rooting induction method of the present embodiment is the same as that of Example 1.

[0061] Under the matching use of the best auxin and the best nutrient solution, after 28 days of cultivation, the roots of the Molan plant grow a large number of new roots, the roots grow vigorously, the plants are strong, and the growth condition is very good.

[0062] The rooting induction method of the present invention is simple, easy to im...

Abstract

The invention provides a water culture Chinese cymbidium rooting inducing method and belongs to the technical field of orchid seedling nursing and propagation. The method comprises the following steps of (1), processing a Chinese cymbidium bare-rooted seedling; (2) preparing an auxin solution; (3) inducing the bare-rooted seedling to root; (4) transplanting to the nutrition solution. The inducing rooting method is simple, easy to realize, clean and environment-friendly, the Chinese cymbidium plants obtained according to the rooting inducing method are robust, are well grown and provide a basis for the detoxification and fast propagation of water culture Chinese cymbidium, a water culture technology for promoting the rooting of the Chinese cymbidium with the auxin appears in China for the first time, and the appreciation value, economical benefits and social benefits of the Chinese cymbidium are further improved.

Description

technical field [0001] The invention belongs to the technical field of orchid seedling breeding and propagation, in particular to a rooting induction method for hydroponic orchids. Background technique [0002] Cymbidium( Cymbidium sinensis) Also known as Baosuilan, it is a perennial herbaceous flower of Orchidaceae and Orchid, and it is a national orchid species with Guangdong characteristics. The flowering period of black orchid is from September to March of the next year. The flower posture is elegant and elegant, and the fragrance is fresh. It has high ornamental value and good market prospect. The conventional cultivation method of Molan is soil cultivation (usually pond mud) or matrix cultivation (commonly used volcanic rock, weathered stone, kaolinite, peat, ceramsite, etc.) (Li Qixiang et al., 2011). The orchids planted by these two cultivation methods are prone to virus infection and fungal diseases such as leaf spot. Up to now, at least 25 kinds of viruses have b...
