Problems solved by technology

The production cost of tissue culture is high, the technical requirements are high, and it is difficult to widely promote
However, the traditional cutting propagation mother plant is directly planted in the soil, it requires a lot of land, the geographical conditions are particular, and it is not easy to control the lignification of the cuttings, etc.

Embodiment 1

[0028]Select an excellent single plant as the mother tree for seed collection. From December to January every year, when the fruit buds are brown or light brown, go up the tree to collect seeds. Dry storage in cloth bags. Soak the seeds in lime water for 7 days in May, then remove the seeds and rinse them with water for 4 times. The cleaned seeds are spread evenly on the sand bed and flattened with wooden boards so that the seeds are slightly sunken in the sand and the upper part is exposed. , do not cover the sand, do not shade, let the sun expose to the sun, and water at 2 o'clock at noon. When watering, the seeds rush out of the seedbed and should be pressed into the sand immediately. When the temperature is low or it rains, use a film to cover the insulation and and protected from rain. When the seeds germinate on the sand bed and grow to a height of 4-5cm, transplant them into the prepared container cup. When transplanting, the seedlings should cut off the roots and only ...

Embodiment 2

[0030] Select an excellent single plant as the mother tree for seed collection. From December to January every year, when the fruit buds are brown or light brown, go up the tree to collect seeds. Dry storage in cloth bags, soak the seeds in lime water for 7 days in July, remove the seeds and rinse them with clean water for 5 times, spread the cleaned seeds evenly on the sand bed, flatten them with wooden boards, make the seeds slightly trapped in the sand, and expose the upper part , do not cover the sand, do not shade, let the sun expose to the sun, and water at 3 o'clock at noon. When watering, if the seeds rush out of the seedbed, they should be pressed into the sand immediately. When the temperature is low or it rains, use a film to cover the heat preservation and Protect from rain. When the seeds on the sand bed germinated and grew to a height of 5 cm, they were transplanted into a prepared container cup. When transplanting, the seedlings would cut off the roots and only ...

Embodiment 3

[0032] Select an excellent single plant as the mother tree for seed collection. From December to January every year, when the fruit buds are brown or light brown, go up the tree to collect seeds. Dry storage in cloth bags. After soaking the seeds in lime water for 8 days in March, take out the seeds and rinse them with clean water for 6 times. The cleaned seeds are evenly spread on the sand bed, flattened with wooden boards, so that the seeds are slightly trapped in the sand, and the upper part is exposed. , do not cover the sand, do not shade, let the sun expose to the sun, and water at 1:00 noon. When watering, if the seeds rush out of the seedbed, they should be pressed into the sand immediately. When the temperature is low or it rains, use a film to cover heat preservation and Get drenched in the rain. When the seeds on the sand bed germinate and grow to 4-5cm high, the transplanted seedlings will cut the roots, and only keep 4cm, and the container cups with a specificatio...

Abstract

The invention discloses a method for culturing teak seedlings by spike culture and rapid propagation in containers. High-quality single teak seeds are used as the parent plants; when growing to 4 to 5 centimeters high, the seedlings sown on a sand bed are transplanted into a parent plant containing cup filled with nutrient substrate, and placed on a lifting seedling culturing bed to be cultured; when the diameter of each parent plant is larger than 0.3 centimeter, the parent plant is cut off from the part 10 to 15 centimeters far from the basic part to promote side branches to germinate; when the seedlings are semi-lignified, side branches are cut off, used as cuttings, inserted into a cutting containing cup filled with substrate and placed on the lifting seedling culturing bed to be cultured; therefore, a large amount of high-quality teak seedlings maintaining the excellent hereditary characters of the parent plants can be propagated rapidly in a short time, and the success rate of cottage reaches 85.1 to 96.6 percent. The method for culturing teak seedlings by spike culture and rapid propagation in the containers is not limited by season or region, and can be used for obtaining excellent propagants in a poor land condition; the moisture and nutrition of the parent plants are easier to control; the method is beneficial to culture of desired cutting spikes; the coefficient of propagation is high; the method is simple; the operation is easy; the production cost is low; and the method for culturing teak seedlings can meet the needs in modern forestry development of China.

Description

technical field [0001] The invention belongs to the technical field of asexual rapid propagation of plants, and relates to a method for growing ears and rapid propagation of seedlings in a teak container. Background technique [0002] Teak (Tectona grandis L.F.) is a deciduous or semi-deciduous broad-leaved tree species belonging to the Verbenaceae (Vcrbenaceae) teak genus (Tectona). Myanmar and Indonesia are known as "national treasures". It is precious and fast-growing, and the average diameter of the 7-year-old teak plantation is about 20cm. Its wood has high density and hardness, is not easy to wear, heavy oily, moisture-proof, moth-proof, extremely corrosion-resistant, stable wood, and is a good material for manufacturing high-end furniture, floors, indoor and outdoor decorations, shipbuilding, open-air buildings, and bridges. Native to Myanmar, Thailand, India, Indonesia, Laos, etc., it is the main afforestation tree species in Southeast Asia. [0003] my country ha...
