LithocarpusoleaefoliusA.Camus-QuercusacutissimaCarruth container seedling grafting breeding method

Abstract

The invention discloses a LithocarpusoleaefoliusA.Camus-QuercusacutissimaCarruth container seedling grafting breeding method comprising the steps of scion acquisition, grafting time, grating, and post-grafting management; selecting QuercusacutissimaCarruth container nursery stock as stock; cutting strong semi lignifications-lignifying branches with no insect disease from LithocarpusoleaefoliusA.Camus seed tree to serve as scion; using cut-grafting method for grafting; carrying out post-grafting management until next spring so as to obtain LithocarpusoleaefoliusA.Camus grafted seedlings for afforestation. The method is a breakthrough in LithocarpusoleaefoliusA.Camus asexual breeding technology; QuercusacutissimaCarruth stock is used for grafting breeding; QuercusacutissimaCarruth container nursery stocks with excellent female parent economic characters are fast and massively breed, and the stock is prosperous in root system; the QuercusacutissimaCarruth stock has strong adaptation capability for natural dry, wet and cold conditions, the LithocarpusoleaefoliusA.Camus seedling can utilize the advantages, so the scion and stock can fast heal and germinate new shoots; the germinated new shoots can grow fast, thus promoting high quality, efficiency and fast development of the LithocarpusoleaefoliusA.Camus, and providing better economic benefits, social benefits and ecology benefits.

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 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 miscellan...

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
