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 ...

Examples

Embodiment 1

[0027] Choose a leeward, sunny place with good water permeability to build a seedbed, fill the seedling container with nutrient soil, and place it neatly on the seedbed. One day before sowing, use potassium permanganate with a weight concentration of 0.2% to disinfect the nutrient soil. Choose common cork oak seeds, soak them with clear water for 1 day before sowing, then dress the seeds with 0.2% carbendazim solution by weight, cover with plastic film for insecticide, and then store the seeds with wet sand. The volume ratio is 2:1. After the seeds are stored and germinated, they germinate from February to March of the next year. The germinated seeds are taken out from the wet sand and sowed in a seedling container filled with nutrient soil. ~2cm thick. The nutrient soil is prepared by mixing uniformly according to the volume ratio of raw materials: red soil: humic soil = 1-2:1. The seedling-raising container adopts a degradable non-woven seedling-growing bag of 8cm×15cm. S...
