Method of producing rooted cutting of arboreous plant

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...
