Problems solved by technology

Chinese patent technology "CN104186164A" discloses a method for growing seedlings of beech tree cuttings, in which the cutting substrate is a mixture of sand and yellow core soil according to 1:4. After verification, it is found that the rooting rate can only reach about 50%.
Most of the cutting substrates in the prior art have the defect of low rooting rate, and the possible reasons mainly include: poor aeration and water retention of the substrate and root infection by plant pathogenic bacteria, etc.

Embodiment 1

[0035] The technology of propagating beech with hardwood cuttings, it comprises the steps:

[0036] Taking beech as the research object, the cutting time was March 25, and the thick fork branches and side branches from the 5-year-old mother tree were selected as cuttings. The cuttings were cut with a length of 12cm and a thickness of 0.5-1.0cm. There are more than 2 strong and full axillary buds, and the lower cut is trimmed at a 45-degree oblique cut. Soak in phytohormone (200mg / L IBA+200mg / L 6-BA) for 9 hours; then insert into the rooting matrix, the depth of inserting into the rooting matrix is ​​half the length of the cuttings, and water thoroughly; the inserting bed is set in the greenhouse, The temperature is 25-30°C, the light time is 6h, and the light intensity is 10000Lux. One month after cutting, move to the outdoor hardening for two months to check the rooting situation. The outdoor hardening uses a sunshade net with a shading rate of 50%, and the temperature is ke...

Embodiment 2

[0044] The technology of propagating beech with hardwood cuttings, it comprises the steps:

[0045] Taking beech as the research object, the cuttage time was April 5th, and the thick fork branches and side branches from the 5-year-old mother tree were selected as cuttings. The cuttings were cut with a length of 15cm and a thickness of 0.5-1.0cm. There are more than 2 strong and full axillary buds, and the lower cut is trimmed at a 45-degree oblique cut. Soak in phytohormone (300mg / L IBA+300mg / L 6-BA) for 6 hours; then insert into the rooting matrix, the depth of inserting into the rooting matrix is ​​half the length of the cuttings, water thoroughly; the inserting bed is set in the greenhouse, The temperature is 25-30°C, the light time is 6-8h, and the light intensity is 8000-10000Lux. One month after cutting, move to the outdoor hardening for two months to check the rooting situation. The outdoor hardening uses a sunshade net with a shading rate of 50%, and the temperature i...

Embodiment 3

[0053] The rooting situation of beech hardwood cuttings of the present invention:

[0054] Different groups were set up to detect the influence of different rooting substrates on rooting.

[0055] Experimental group: the rooting matrix prepared in embodiment 1;

[0056] Matched group 1: 20 parts of vermiculite, 10 parts of perlite, 20 parts of peat soil, all the other are the same as embodiment 1;

[0057] Control group 2: 3 parts of biological bacteria agent, 10 parts of perlite, 20 parts of peat soil;

[0058] Control group 3: 3 parts of biological bacteria agent, 20 parts of vermiculite, 10 parts of perlite;

[0059] Control group 4: 3 parts of biological bacteria agent, 10 parts of perlite, 20 parts of peat soil;

[0060] The cutting process of each group is the same as in Example 1, and the number of cuttings in each group is 200. For the cutting conditions of each group substrate, see Figure 1-3 As shown, compared with the control group 1-4, the cutting rooting effe...

Abstract

The invention belongs to the technical field of plant cutting, and discloses a process for breeding zelkova schneideriana by hardwood cutting. The process includes the steps: selecting late March to early April as cutting time; selecting thick and strong fork branches and side branches on five-year-old seed trees as cuttings; placing the cuttings into plant hormones to soak the cuttings for 6-9 hours; inserting the cuttings into rooting media, and thoroughly watering on the media; arranging a cutting bed in a greenhouse; moving the cutting bed to outdoor space after cutting is implemented forone month to harden seedlings for two months, and inspecting rooting conditions. The lengths of cut cuttings are 12-15cm, the thicknesses of the cut cuttings are 0.5-1.0cm, each cutting at least contains more than two strong and full axillary buds, lower cutting openings of the cut cuttings are trimmed into 45-degree inclined cutting openings, half of the cut cuttings are inserted into the rootingmedia, the temperature in the greenhouse is 25-30 DEG C, illumination time is 6-8h, and the illumination intensity is 8000-10000Lux. By the aid of the process for breeding the zelkova schneideriana by hardwood cutting in spring, material sources are wide, and rooting rate is high.

Description

technical field [0001] The invention belongs to the technical field of plant cuttings, and in particular relates to a process for propagating beech trees by using hard branch cuttings. Background technique [0002] Beech, also known as zelkova, is a deciduous tree species of the genus Beech in the family Ulmaceae. Arbor, up to 30 meters, DBH up to 100 cm; bark off-white or brownish-gray, exfoliating irregularly; current year branches purple-brown or brown, sparsely pubescent, then falling off gradually; leaves thin papery to thick Papery, with great variation in size and shape, ovate, oval or ovate-lanceolate, 2-9 cm long, 1-4 cm wide, apex acuminate or caudate acuminate, some bases slightly deviated, sparse Round or shallow heart-shaped, with crenated serrations on the edge, with short pointed heads, 8-14 pairs of lateral veins; the upper midrib is concavely hairy, and the lower side is glabrous. Petioles 4-9 mm long, pubescent. Male flowers have very short stalks, abo...
