Problems solved by technology

Due to the hard seeds of Acaeaceae, 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 Fructus aeruginosa 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 Fructus fragrans.

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 oak seeds, soak the seeds with water for 1 day before sowing, then dress the seeds with a carbendazim solution with a weight concentration of 0.2%, and cover with a 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-grow...

[0030]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 oak seeds, soak the seeds with water for 1 day before sowing, then dress the seeds with a carbendazim solution with a weight concentration of 0.2%, and cover with a 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 will germinate from March to April of the next year. The germinated seeds are taken out from the wet sand and sown 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 = 2:1.

Abstract

The invention discloses a Lithocarpushancei(Benth.)Rehd-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 Lithocarpushancei(Benth.)Rehd seed tree to serve as scion; using cut-grafting method for grafting; carrying out post-grafting management until next spring so as to obtain Lithocarpushancei(Benth.)Rehd grafted seedlings for afforestation. The method is a breakthrough in Lithocarpushancei(Benth.)Rehd 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 Lithocarpushancei(Benth.)Rehd 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 Lithocarpushancei(Benth.)Rehd, 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. Background technique [0002] hard shell Ke ( Lithocarpushancei (Benth.) Rehd ) also known as Chipigang (Taiwan), Jiuyan (Jiangxi), Bangzhang (Hunan), Shishanzhao (Guangxi), belongs to Fagaceae (Fagaceae) Lithocarpus (Lithocarpus), tree, rarely more than 15 meters high, All parts glabrous except inflorescence rachis and cupule gray pubescent. Branchlets yellowish gray or gray, often with a thin transparent waxy layer. Leaves are papery to hard leathery, ovate, obovate, broadly elliptic, obovate-elliptic, narrowly oblong-elliptic or lanceolate. The flowering period is from April to June, and the fruit matures from September to December of the following year. Bark dark gray or brownish gray, 6-10 mm thick, irregularly lobed longitudinally, peeled in small flakes, inner bark light brown, w...
