Embodiment Construction

[0023] The present invention comprises the steps:

[0024] a) Confirm that the ancient tree 1 is still in a healthy growth state and the root system is still good, and find out the location and degree of the tree hole or other depressions and defects in the ancient tree 1; the timing of repair is spring or autumn.

[0025] b) The first rejuvenation repair of the scion at the bottom of the breach: make breaches in tree holes or other recessed defects, and use The scion is grafted multiple times, so that while the tree hole or other sunken defect parts of the old tree are repaired, the vitality is also restored and the growth is more vigorous;

[0026] refer to figure 1 removing the rotten tissue at the damaged part of the breach of the old tree 1, disinfecting and antisepsis the breach, filling and sealing the heartwood part 3, making the primary joint surface 11 of the rootstock at the cambium part of the sapwood at the bottom of the breach, Cleaning of joint surfaces;

Abstract

The invention discloses a rejuvenation-type repairing method of holes or depressed defects of rare old trees, comprising the steps of manufacturing a primary joint surface of a stock on the cambium part of the laburnum at the bottom of the slit of the old tree; grafting a plurality of scions on the joint surface of the stock; after surviving, manufacturing a second joint surface of the stock attaching the scions on the cambium part of the laburnum on the upper part of the slit of the old tree; finally, manufacturing third joint surfaces between the slit and the scions, and the scions, so that the broken laburnums on the holes or depressed defects of the old tree trunk are communicated again by bridge function of the scions and the substances in the tree are transported vertically and thedepressed defects are supported well; thus the old tree is saved, rejuvenated and repaired, and the unique landscape symbolic significance and carried historical and cultural significance of the old tree are continued; thus the method has research value, ecological benefit, economic benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of ancient tree restoration, in particular to a rejuvenating repair method for hollows or sunken defects of rare ancient trees. Background technique [0002] Precious and rare ancient trees are a beautiful and iconic landscape in the garden, carrying historical and cultural significance, and also have scientific research value, and are rare and important specimens.

But how to take appropriate method to carry out on-the-spot rescue and repair in time, there is no effective good way so far. Trees reproduce in two ways: sexual reproduction and asexual reproduction. When these ancient trees are still able to bear fruit, the collected seeds can be used to plant, of course, the tree species can be continued, but the unique genotyp...
