Asexual rapid propagation method for lithocarpus oleaefolius

Abstract

The invention discloses an asexual rapid propagation method for lithocarpus oleaefolius. The method comprises the steps of: scion collection; grafting time; grafting; and post-grafting management. The method specifically comprises: selecting a quercus variabilis container seedling as a rootstock; clipping robust and pest-free branches which are from being semi-lignified to lignified from a seed tree of lithocarpus oleaefolius as scions; performing grafting by adopting a cleft grafting method; and performing post-grafting management till grafted seedlings of lithocarpus oleaefolius obtained in the next spring can be discharged out of a garden for afforestation. The method disclosed by the invention is a breakthrough of an asexual propagation technology for lithocarpus oleaefolius. By performing grafting propagation by using the quercus variabilis rootstock, quercus variabilis container seedlings which maintain excellent economical characteristics of a female parent are massively and rapidly propagated, and the root systems of the seedlings are developed; By virtue of the advantageous characteristic that the quercus variabilis rootstock has a relatively strong adaptive capacity to natural environments such as drought and barren environments, scions and rootstocks of the lithocarpus oleaefolius seedlings can be quickly healed and germinate new tips, and the germinated new tips are quick to grow, so that high-quality, high-efficiency and quick development of lithocarpus oleaefolius are accelerated. The preparation method has a relatively good economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for rapid vegetative propagation of Lavenderia. Background technique [0002] Lavender ( Lithocarpusoleae efolius A.Camus), also known as Lithocarpus olifolia, Lavender leaf, is an arbor of Fagaceae (Fagaceae) genus Lithocarpus, 8 to 15 meters high, with almost glabrous bud scales, annual branches, petioles, leaf backs and inflorescences The shaft is covered with brown rust or brown-yellow villous hairs that are easy to fall off, and the biennial branches are dark brown and black, and the lenticels are very small and difficult to see. Bark dark gray to gray black, not cracked, bark about 8mm thick at a height of about 13 meters, inner bark light reddish brown, prominent ridges. The fruit contains 50% to 60% starch. Distributed in the south of Jiangxi, Fujian, Hunan, and Guizhou, Guangdong, and Guangxi. Born in miscellaneous forests in mountains at ...

Problems solved by technology

Since the seeds of Laceae 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 being able to offset the reduction in resources.

However, in traditional production, the germination rate of the seeds of Lacena officinalis without any hormone treatment is often only about 50%, and the germination time is late and the emergence of seedlings is not uniform, which limits the large-scale planting of Lacena officinalis
