Problems solved by technology

Therefore, according to traditional scion methods, it is difficult to ensure consistent rooting ability of the scion, making it extremely difficult to efficiently produce rooting cuttings
[0009] As a result, in many cases, the production of rooted cuttings can only be abandoned, which is an industrial loss

Embodiment 1

[0065] Begin to grow the twig (epicornic branch) that leaf bud just bloomed after cutting germination from the mother tree of biennial blue eucalyptus, prepare the long scion of 10cm, keep a pair of leaves, other lower leaves are removed. Remove the upper half of the pair of leaves and cut the base of the scion with a knife. Soak the upper part of the scion in the bactericidal solution for 5 seconds, and absorb water for a day and a night. Then, the prepared scion is inserted into the medium, which is mixed with equal amounts of vermiculite and sphagnum moss, and filled in the insert tray after being moistened.

[0066] An MHF (three-layer porous fiber) membrane module (Mitsubishi Rayon Co., Ltd.) was used as the membrane module MO in the process shown in FIG. 1 . In a greenhouse under natural light, the amount of light is 0.10 (1y / min) or higher, each spray is 60 seconds, and the interval is 15 minutes, and the carbon dioxide solution is intermittently sprayed on the scion. ...

Embodiment 1

[0069] Replace carbon dioxide solution and oxygen solution with tap water, repeat implementation embodiment 1 in 43 days of raising seedlings.

[0070] Table 1 shows the rooting rate in Example 1 and Comparative Example 1 after 43 days of Eucalyptus blue scion seedling cultivation.

[0071] Rooting rate:

[0072] test

[0073] The results in Table 1 show that when the scion is growing seedlings, the method of the present invention that provides high-concentration carbon dioxide solution and oxygen solution to the scion can be used to promote plant (in the present embodiment, Eucalyptus blue) scion rooting. A variety of plants have obtained similar results after using this method, such as Eucylyptus camaldulensis Acacia and Eucalyptus.

Embodiment 2a

[0075] Cutting Acacia auricularis (biennial, 50cm high) potted seedlings are used as mother trees. Branches are collected from the 5th leaf at the top to the 9th leaf position, and other leaves other than the pair of blades at the tip of the ear are removed to prepare a scion about 8 cm long. Remove the upper half of the pair of leaves and cut the base of the scion with a knife. Soak the upper part of the scion in a disinfectant solution for 5 seconds and absorb water for a day and a night. Then, insert the prepared scion into the vermiculite medium that is placed in the insert tray after filling it with moisture,

[0076] An MHF (three-layer porous fiber) membrane module (Mitsubishi Rayon Co., Ltd.) was used as the membrane module MO in the process shown in FIG. 1 . Every day in 48 days of raising seedlings, under light conditions (12 hours by day, 24 ℃ of temperature, 12 hours at night, 20 ℃ of temperature), spray carbon dioxide solution on the scion with interval 1 hour e...

Abstract

It is intended to propose a method of improving rooting ability of a cutting which is applicable to afforestation on a mass scale, can be easily controlled and enables improvement in rooting ability even in a hardly rooting arboreous plant. In a method of putting a cutting into a medium to give a rooted cutting, water containing at least one member selected from among carbon dioxide, oxygen, carbonate ion and hydrogencarbonate ion dissolved therein is supplied to the cutting to thereby promote the rooting of the cutting. The water is supplied by intermittently spraying or sprinkling. The arboreous plant is exemplified by those belonging to the genera Eucalyptus and Acacia.

Description

technical field [0001] The invention relates to a production method of rooting cuttings of woody (arboreous) plants. Rooting cuttings refer to the seedlings collected from the scions on the trunks of fine plants, which are used for large-scale afforestation and other purposes. Background technique [0002] A technique for increasing plant yield by activating plant photosynthesis by dispersing carbon dioxide-dissolved water on the leaves of plants has been disclosed, for example, in Unexamined Japanese Patent Application Nos. 61-18131 and 08-84530. [0003] Plants are roughly divided into woody plants with woody stems (bark) and herbaceous plants with flexible and pulpy aerial parts but not woody. As we all know, usually, in the commercial nursery of woody plants, there are generally seedlings formed by germination from seeds and clonal seedlings obtained by cutting, grafting or cell culture. Specifically, cutting is the most convenient and economical technique for obtainin...
