Problems solved by technology
Because areca seeds 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
In traditional production, the germination rate of areca seeds without any hormone treatment is often only about 50%, and the germination time is late and the emergence of seedlings is irregular, which limits the large-scale planting of areca

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 areca. 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 and lignified from a seed tree of lithocarpus areca as scions; performing grafting by adopting a cleft grafting method; and performing post-grafting management till grafted seedlings of lithocarpus areca obtained in spring in the next year 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 areca. By performing propagation by grafting by using the quercus variabilis rootstock, quercus variabilis container seedlings which maintain excellent economical character of a mother 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 areca 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 areca are accelerated. The preparation method has 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 palmetto. Background technique [0002] Areca (Lithocarpusareca (Hick.etA.Camus) A.Camus), is a tree of the family Fagaceae (Lithocarpus), 10-15 meters high, with off-white branchlets, glabrous, and lenticels. Leaves are papery, oblanceolate or narrowly long elliptic, 13-25 cm long, 3.5-5.5 cm wide, both ends narrowly pointed, base decelerates, a few lobed sharp teeth or entire margins on the upper part of the leaf margin, Midrib slightly raised on leaf surface, lateral veins 9 to 15 on each side, slightly sunken on leaf surface, distinct branch veins, same color on both sides, glabrous or tufted in axils of veins; petiole 0.5 to 1.5 cm long. Male spikes are axillary on a single ear, with rare short branches and conical shape, 5-8 cm long, many and dense flowers, slender filaments, rather long, slender infloresc...
