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 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...

Abstract

The invention discloses an asexual rapid propagation method for lithocarpus carolinae. 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 carolinae as scions; performing grafting by adopting a cleft grafting method; and performing post-grafting management till grafted seedlings of lithocarpus carolinae 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 carolinae. By performing grafting propagation by using the quercus variabilis rootstock, quercus variabilis container seedlings which maintain excellent economical characters 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 carolinae 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 carolinae are accelerated. The 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 the chrysanthemum. 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 drilled Sh...
