Liriodendron tulipifera cutting propagation method

Abstract

The invention discloses a liriodendron tulipifera cutting propagation method. The liriodendron tulipifera cutting propagation method comprises the following steps that healthy and strong trees free of diseases and insect pests are selected and 1-2a thick and solid branches are sheared, wherein the length of shoots ranges from 13 cm to 16 cm, and each shoot has 2-3 buds; cuts of cuttings are flat, the distance from each upper cut to a nearest bud is 3 cm, and the distance from each lower cut to a nearest bud is 0.5-1.0 m; the upper physiological ends of bundled cutting shoots are upwards soaked in flowing water before cuttage, the upper cuts are not submerged in water, and the soaking time is 5-7 days; therefore, rooting can be promoted, spouting is advanced, and the growing amount of nursery stocks can be further increased; the cutting shoots are exposed out of the ground for 1-2 cm when the cuttings are buried in soil in a straight cutting mode, and one-bud exposure is preferable; the planting row space is 20 cm*30 cm, watering is performed after cuttage, and the cuttings are covered by using plastic films. By means of the liriodendron tulipifera cutting propagation method, cutting rot can be prevented, cutting rooting and propagation can be further accelerated, and the survival rate of propagated liriodendron tulipifera cuttings is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tree cutting propagation, in particular to a cutting propagation method of Liriodendron tulipifera. Background technique [0002] Liriodendron tulipifera is an excellent ornamental and timber tree species. It belongs to deciduous trees. Its trunk stands tall, the canopy is oval, the bark is gray-brown, the branches are purple-brown, and the leaves are wide. . [0003] Since the introduction of Liriodendron chinensis into my country, many breeding experiments have been carried out on it, including: seeding propagation, cutting propagation and tissue culture propagation. However, it has been found in a large number of cutting experiments that the cuttings of Liriodendron tulipifera take longer to take root, and the spikes are easy to rot, which affects the survival rate of the cuttings of Liriodendron tulipifera. Contents of the invention [0004] For the problems existing in the above-mentioned pri...
