Propagation method of lithocarpus calophyllus grafted quercus acutissima carruth container seedlings

Abstract

The invention discloses a propagation method of lithocarpus calophyllus grafted quercus acutissima carruth container seedlings. The method comprises the steps of scion collecting, grafting time, grafting and management after grafting; quercus acutissima carruth container seedlings are selected to serve as rootstock, semi-lignified to lignified branches which are robust and free of diseases and insect pests are pruned from a lithocarpus calophyllus seed tree to serve as scions, grafting is conducted through a cut-grafting method, management after grafting is conducted, the lithocarpus calophyllus grafted seedlings are obtained in spring next year, the seedlings can be moved out of a nursery for forestation. The propagation method is a breakthrough of the vegetative propagation technology of lithocarpus calophyllus, quercus acutissima carruth rootstock is utilized for conducting grafting propagation, the quercus acutissima carruth container seedlings maintaining good economic characters of a female parent are propagated massively and rapidly, and the roots of the seedlings are developed; lithocarpus calophyllus seedlings rely on the advantages of being high in adaptive capacity to drought, wet and cold natural environments of rootstock quercus acutissima carruth, the scions and the rootstock can be rapidly regrown and sprout young sprouts, the young sprouts grow rapidly, high-quality, efficient and rapid development of lithocarpus calophyllus is facilitated, and good economic benefit, social benefit and ecological benefit are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a propagation method for grafting Quercus japonica container seedlings of Quercus japonica. Background technique [0002] Meiyeke ( Lithocarpus calophyllus ) is also known as red leaf citron (Jiangxi), sclerophyllum, chrysanthemum, yellow-backed oak (Guangdong), and Zhecone (Guangxi). 1 m, the upper part of new branches is sparsely puberulent, and the biennial branches are brownish black with lenticels. Leaves hard leathery, broadly elliptic, ovate or oblong, 8-15 cm long, 4-9 cm wide, apex acuminate or shortly acuminate, caudate, base nearly round or shallow lobe-shaped, sometimes a The sides are slightly short or oblique, with 7-11 lateral veins on each side, sunken on the leaf surface, sharply bent upward near the leaf edge and disappearing, the branch veins are very slender, nearly parallel to each other, the back of the leaf is glabrous, but has a thick ...

AI Technical Summary

Problems solved by technology

Since the seeds of Meiyeke are hard seeds, there are many factors in the natural germination process that lead to a low success rate of seed germination, and the natural germination of seeds is far from equal to the reduction of resources

However, in traditional production, the germination rate of Meiyeke seeds without any hormone treatment is often only about 50%, and the germination time is late and the emergence is irregular, which limits the large-scale planting of Meiyeke
