Problems solved by technology
[0004] The breeding of Liriodendron chinensis mainly includes cuttings and tissue culture rapid propagation, and the promotion of tissue culture rapid propagation technology is difficult. At present, cutting propagation is the most widely used, but cutting propagation has the disadvantages that the cut is easy to rot and the survival rate is low; The technology is to apply a certain amount of sterilizing drugs on the incisions. The disadvantage of this method is that the sterilization time is short, the drug effect is not long-lasting, and it will fail soon after the cuttings. Therefore, although it has a certain antiseptic effect, the survival rate of the cuttings is still low.

Embodiment 1
[0030] Example 1 A kind of antiseptic cutting substrate
[0031] Weigh the following antiseptic cutting matrix components: 10 parts by weight of perlite, 5 parts by weight of vermiculite, 3 parts by weight of jute, 2 parts by weight of raw land, 2 parts by weight of cork, 2 parts by weight of oyster shells, 30 parts by weight of peat soil, elm bark 20 parts by weight of powder, stirred and mixed, sprayed with an appropriate amount of water, and stirred while spraying, so that the water content of the substrate was 32%, and the antiseptic cutting substrate can be obtained.
Embodiment 2
[0032] Embodiment 2 A kind of antiseptic cutting matrix
[0033] Weigh the following anti-corrosion cutting matrix components: 15 parts by weight of perlite, 9 parts by weight of vermiculite, 4 parts by weight of jute, 4 parts by weight of raw land, 3 parts by weight of cork, 5 parts by weight of oyster shells, 40 parts by weight of peat soil, elm bark 30 parts by weight of powder, stir and mix, spray appropriate amount of water, and stir while spraying, so that the water content of the substrate is 35%, and the antiseptic cutting substrate can be obtained.
Embodiment 3
[0034] Embodiment 3 A kind of antisepsis cuttage matrix
[0035] Weigh the following anti-corrosion cutting matrix components: 12 parts by weight of perlite, 6 parts by weight of vermiculite, 3.5 parts by weight of jute, 3 parts by weight of raw land, 2.5 parts by weight of cork, 4 parts by weight of oyster shells, 36 parts by weight of peat soil, elm bark Powder 27 parts by weight, stir and mix, spray appropriate amount of water, and stir while spraying, so that the water content of the substrate is 33%, and the antiseptic cutting substrate can be obtained.

Abstract
The invention provides a liriodendron tulipifera hardwood cutting method. The method comprises the steps of cutting selection, cutting bed preparation, cutting slip treatment, cutting, cutting aftertreatment and transplantation; in the cutting selection step, liriodendron tulipifera hardwood is selected as a cutting test material in spring, cuttings are 0.6-0.7 cm thick and cut into sections, and each section is 18-22 cm long and has 2-3 axillary buds and 2-4 leaves. In the cutting bed preparation step, an anti-corrosion cutting medium is uniformly spread all over a seedbed, the thickness of the medium is 20-22 cm, water is sprayed once, and the humidity of the medium is 50%-55%. In the cutting step, full-automatic atomizing cutting is adopted, the cutting depth is 5 cm, and the cutting distance between seedlings is 30*30 cm. The cutting survival rate is 99.2%-99.7% after the method is used for cutting cultivation of liriodendron tulipifera.
Description
technical field [0001] The invention relates to a breeding method of Liriodendron americanum, in particular to a method for cutting hard branches of Liriodendron americana, belonging to the technical field of plant breeding. Background technique [0002] Liriodendron in Phnom Penh, also known as tulip tree, is a cultivated variety of Liriodendron in Magnoliaceae. Large deciduous tree. The main difference from Liriodendron is that the leaves are wider and shorter, the lateral fissures are shallower, there are often small lobes near the base, the leaf ends are often concave, the back of the young leaves has fine hairs, the flowers are larger and shaped like tulips, the petals are light yellow-green and The inner side near the base is orange-red; the main difference from the original species of Liriodendron tulipifera is that the leaf edges are yellow. Light-loving, cold-resistant than Liriodendron tulipifera, adult trees can withstand short-term severe cold of -25 ~ -30°C, b...
