Embodiment 1

[0020] The present embodiment provides a kind of method of hard branch cutting of zelkova simple electric heating hotbed, and specific steps are as follows:

[0021] 1. Slotting machine build:

[0022] Choose a relatively dry flat ground indoors or in a greenhouse, and lay cutting beds with bricks or other suitable materials. The width of the cutting bed is 1.2-1.4 m, and the height is 25-30 cm. Lay a layer of insulation material such as straw on the bottom layer, cover it with a film, and then lay 3 to 5 cm thick coarse river sand. The sand surface is required to be scraped so that the geothermal lines can be evenly distributed. Place one wooden strip with a length of 1.2-1.4 m on the river sand at both ends and in the middle of the slotting bed, and drive nails into the wooden strip at intervals of 5-8 cm. When wiring, wire back and forth between the wooden strips at both ends. The ground heating wire is required to be straightened evenly, moderately tight, not damaged, and...

Embodiment 2

[0037]Two to three weeks before the beech sprouts in spring, collect annual branches from the mother tree as cuttings, tie them into small bundles, store them in a low-temperature shaded place, lay straw or yellow sand on the ground, discharge the small bundles of cuttings vertically, and close them during the day Doors and windows, open the windows at night for ventilation, pay attention to proper moisturizing, so that the cuttings maintain an appropriate water content. At the same time, a cutting bed with a width of 1.2-1.4 m and a height of 25-30 cm is laid indoors with bricks and other materials. Lay 3 to 5 cm of wet sand on top of the laid geothermal line, level the sand surface, and prepare for placing cuttings.

[0038] On the day of cutting, cut cuttings with a length of 12-15 cm and a diameter of 0.8 cm-1.0 cm from the cuttings; the upper end is cut obliquely about 1-2 cm above the top bud, and the lower end is about 0.5-1 cm below the root protomum. Cut. The cut cu...

Embodiment 3

[0042] Two to three weeks before the beech sprouts in spring, collect annual branches from the mother tree as cuttings, tie them into small bundles, store them in a low-temperature shaded place, lay straw or yellow sand on the ground, discharge the small bundles of cuttings vertically, and close them during the day Doors and windows, open the windows at night for ventilation, pay attention to proper moisturizing, so that the cuttings maintain an appropriate water content. At the same time, a cutting bed with a width of 1.2-1.4 m and a height of 25-30 cm is laid indoors with bricks and other materials. Lay 3 to 5 cm of wet sand on top of the laid geothermal line, level the sand surface, and prepare for placing cuttings.

[0043] Cuttings of different lengths and thicknesses were cut from the cuttings on the day of cutting, among which the average length of thin cuttings was 11.60 cm and diameter 0.57 cm, the average length of medium cuttings was 12.16 cm and diameter 0.87 cm, a...

Abstract

The invention discloses a hard branch cuttage method of zelkova schneideriana by adopting an electrically-heated bed. The electrically-heated temperature control cuttage bed is constructed by adoptingmaterials such as a thermal insulation material, river sand, geothermal electric wires and a temperature controller; 2-3 weeks before germination of the zelkova schneideriana in spring, annual cuttage branches are collected and stored in a shady low-temperature place, and the water content of the cuttage branches is adjusted; cuttage slips with the length of 12-15 centimeters and the diameter of0.8 centimeter or above are cut off, the upper ends of the cuttage slips are obliquely cut, the lower ends of the cuttage slips are cut flat, the cuttage slips are bundled into small bundles, and thecuttage slips are immersed in composite rooting liquid with 50-75 ppm NAA and 100-150 ppm IBA for 6-14 hours; during cuttage, the cuttage slip bundles are arrayed in the cuttage bed, the portions among the cuttage slip bundles are filled with the wet river sand; during management after cuttage, the temperature of the electrically-heated bed is controlled at 24 DEG C-28 DEG C, the relative humidityis kept at 70%-85%, and carbendazim pesticide liquid is sprayed once a week. According to the hard branch cuttage method of the zelkova schneideriana by adopting the electrically-heated bed, electricheating for temperature increasing is utilized for increasing the rooting speed of the cuttage slips of the hard branches of the zelkova schneideriana, the rooting rate and the survival rate are increased, and a new technical way is provided for rapid propagation and seedling cultivation of the zelkova schneideriana.

Description

technical field [0001] The invention belongs to a method for raising seedlings in the field of forestry, and in particular relates to a method for cutting hard branches of beech trees in a simple electric heating hotbed. [0002] technical background [0003] Beech( Zelkova schneideriana ) is a large deciduous tree belonging to the genus Beech in the family Ulmaceae. The shape of the beech tree is tall and beautiful, and the leaf color changes with the four seasons. It has the characteristics of strong stress resistance, strong wind resistance, drought resistance, less pests and diseases, smoke resistance, and pollution resistance. It is an ideal choice for urban and rural greening and building windbreak forests. Excellent tree species. [0004] In the natural state, it is difficult to collect beech seeds, the germination rate is low, and the natural regeneration is difficult, resulting in very scarce wild resources. In the production of beech seedlings, sexual reproductio...
