Example Embodiment

[0027] Example 1

[0028]Select a good single plant as the mother tree for seed collection. From December to January every year, the fruit seed buds are brownish yellow or light brown when the tree is collected. Dry storage in cloth bags. After soaking the seeds in lime water for 7 days in May, remove the seeds and rinse them with clean water for 4 times. The clean seeds are evenly spread on the sand bed and flattened with a wooden board so that the seeds are slightly trapped in the sand and the upper part is exposed. , Do not cover sand, do not shade, expose to the sun, and water at 2:00 noon. When watering, if the seeds rush out of the seedbed, they should be pressed into the sand immediately. and protection from rain. When the seeds on the sand bed grow to a height of 4 to 5 cm, transplant them into the prepared container cups. When transplanting, the seedlings should be cut off and only 3 cm should be reserved. Use a container cup with a size of 16 × 18 cm to fill the sub...

[0030] Select a good single plant as the mother tree for seed collection. From December to January every year, the fruit seed buds are brownish yellow or light brown when the tree is collected. 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 clean seeds evenly on the sand bed, and flatten them with a wooden board, so that the seeds are slightly trapped in the sand and the upper part is exposed. , Do not cover sand, do not shade, let the sun insolate, and water at 3:00 noon. When watering, if the seeds rush out of the seedbed, they should be pressed into the sand immediately. Protect from rain. When the seeds germinate on the sand bed and grow to a height of 5cm, transplant them into a prepared container cup. When transplanting, the seedlings should be cut off and only 2cm should be kept. Use a container cup with a size of 12 × 16cm to fill the substrate with...

[0032] Select a good single plant as the mother tree for seed collection. From December to January every year, the fruit seed buds are brownish yellow or light brown when the tree is collected. Dry storage in cloth bags. After soaking the seeds in lime water for 8 days in March, remove the seeds and rinse them with clean water for 6 times. The clean seeds are evenly spread on the sand bed and flattened with a wooden board, so that the seeds are slightly trapped in the sand and the upper part is exposed. , Do not cover sand, do not shade, 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. rained. When the seeds germinate on the sand bed and grow to a height of 4-5cm, the transplanted seedlings should be cut off and only 4cm should be kept. For transplanting, a container cup with a size of 20×20cm is used to pack the matrix for planting the mother plant (the matrix ...

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...
