Problems solved by technology

Due to the hard seeds of hongxinke, there are many factors in the natural germination process that lead to low success rate of seed germination, and the natural germination of seeds is far less than the reduction of resources
In traditional production, the germination rate of Hongxinke 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 Hongxinke

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...

Abstract

The invention discloses a reproduction method for grafting Quercus acutissima Carruth container seedlings on Lithocarpus carolinae (Skan) Rehd. The reproduction method comprises the working procedures of scion collecting, grafting time management, grafting and management after grafting, and comprises the following steps: selecting Quercus acutissima Carruth container seedlings as rootstocks; shearing robust semi-lignified or lignified branches without diseases or insect pests as scions from a seed tree of Lithocarpus carolinae (Skan) Rehd; grafting by using a cut-grafting method; and managing after grafting, wherein the Lithocarpus carolinae (Skan) Rehd grafted seedlings obtained in the spring of the next year can be transplanted from a garden and then planted in a forest. The reproduction method is a breakthrough of an asexual reproduction technology for the Lithocarpus carolinae (Skan) Rehd, grafting and reproduction are implemented by the Quercus acutissima Carruth rootstock, a large number of Quercus acutissima Carruth container seedlings with excellent economic characters of a female parent can be quickly reproduced, and root systems of the seedlings are developed; and owing to the advantage of the Quercus acutissima Carruth rootstock with relatively high adaptive capacity on natural environments such as drought, wetness and coldness, the scions of the Lithocarpus carolinae (Skan) Rehd seedlings can be quickly healed with the rootstock and new shoots can germinate, the newly germinated shoots grow rapidly, high-quality, efficient and quick development of the Lithocarpus carolinae (Skan) Rehd is promoted, and better economic benefit, social benefit and ecological benefit are obtained.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a propagation method of grafted Quercus japonica container seedlings. Background technique [0002] Heart Ke ( Lithocarpus carolinae (Skan) Rehd ), is a tree of the family Fagaceae (Fagaceae) of the genus Lithocarpus, about 20 meters high, 40 cm in diameter at breast height, and the top bud scales are triangular and long-lanceolate. Raw lenticels, branches, bud scales, and leaves glabrous. Leaves thick papery, oblong, sparsely obovate-oblong, 13-18 cm long, 4-6 cm wide, apex caudate shortly pointed, base wedge-pointed, midrib slightly raised on leaf surface, or upper segment flat , 15-20 on each side of the lateral veins, reaching to the tooth end of the leaf margin, or sharply curved upward near the leaf margin, gradually slender and submerged, with stellate trichomes in the vein axils, the lower part of the leaf margin is entire, and the upper part is drill...
