Cultivation method for rapid propagation of Acer pentaphyllum twigs

Abstract

The invention belongs to the technical field of Acer pentaphyllum cultivation, and discloses a cultivation method for rapid propagation of Acer pentaphyllum twigs. Budding twigs are adopted to breed Acer pentaphyllum seedlings, the budding twigs have a plurality of budding stem segments, so that materials are easy to obtained; after the budding twigs are sterilized, germination of clustered shootscan be induced, less materials are needed, and inducements are not limited by small number of amount and seeds of existing Acer pentaphyllum theoretically so that germination amount and germination efficiency of the clustered shoots and axillary buds of the budding stem segments can reach the maximum in a short time. According to the cultivation method, under the premise of ensuring maximum proliferation efficiency, continuous germination of the clustered shoots and the axillary buds of the budding stem segments in the process of proliferative cultivation is promoted to improve survival rateand yield of the Acer pentaphyllum seedlings; adding new ingredients in a strong seedling medium is not needed, so that proportioning costs of the medium are greatly reduced, and by adopting the cultivation method to conduct seedling hardening, seedling-hardening survival rate of the Acer pentaphyllum seedlings can reach more than 80%.

Description

Technical field [0001] The invention belongs to the technical field of Acer quinquefolia cultivation, and particularly relates to a method for cultivating the branches of Acer quinquefolia for rapid propagation. Background technique [0002] Acer quinquefolia is an endemic species in Sichuan, China, which grows in river valleys at an altitude of 2200-3000 meters. Acer quinquefolia was first discovered by J.F.Rock in Muli in 1929 and named by Professor Diels of Germany in 1931. Deciduous trees, up to 10 meters high. The bark is dark brown or gray-brown, often split into irregular flakes and fall off. The branchlets are cylindrical and glabrous; the original branches are purple, and the perennial branches are purple-brown with oval lenticels. Winter buds are conical, ovate scales, sharp-pointed apex, purple, and arranged in complex tiles. Palmate compound leaf, with leaflets 4-7, usually 5; leaflets papery, narrow lanceolate, 5-9 cm long, 1.4-1.7 cm wide, apex acute, base cunea...

AI Technical Summary

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: the current artificial propagation technology of Acer pentaphyllum only has seed propagation, and because the seeds are difficult to collect, the germination rate is low and the propagation speed is slow.
