Embodiment 1

[0043] Start processing the collected seeds at the end of March, put the lime with the same weight as the seeds in a vat or vat, then add water 10 times the weight of the lime, and stir evenly with a wooden stick. Put the seeds in cloth bags, woven bags or mesh bags with a length of 80cm and a width of 40cm, 1 bag of 5 kg, tie the mouth of the bag and soak it in lime water, turn it over and over again to make the lime water soak into the bag, and finally press stones on the bag or heavy objects such as bricks, the bag is completely soaked in lime water. Turn the bag once a day and stir the lime water with a wooden stick. After soaking for 5 days, take out the seeds, rinse them with clean water repeatedly, drip dry water, soak them in 100mg / L gibberellin for 12 hours, spread the seeds evenly on the sand bed, and step on them with a wooden board to trap 1 / 4 of the seeds in the sand , do not cover the sand, do not shade, keep the sand moist, and water once in the morning, middle...

Embodiment 2

[0045] The collected seeds start to process the seeds in the first ten days of April. Put lime the same weight as the seeds in a vat or vat, then add water 12 times the weight of the lime, and stir evenly with a wooden stick. Pack the seeds in cloth bags, woven bags or mesh bags with a length of 90cm and a width of 50cm, 1 bag of 8 kg, tie the mouth of the bag and soak it in lime water, turn it over and over again to make the lime water soak into the bag, and finally press stones on the bag or a heavy object such as a brick so that the bag is completely submerged in the lime water. Turn the bag once a day and stir the lime water with a wooden stick. After soaking for 8 days, take out the seeds, rinse them with clean water repeatedly, drip dry water, soak them in 150mg / L gibberellin for 9 hours, spread the seeds evenly on the sand bed, and step on them with a wooden board to trap 1 / 3 of the seeds in the sand , do not cover the sand, do not shade, keep the sand moist, and water...

Embodiment 3

[0047] Start processing the collected seeds in mid-April, put lime the same weight as the seeds in a vat or vat, then add water 13 times the weight of the lime, and stir evenly with a wooden stick. Put the seeds in a cloth bag, woven bag or mesh bag with a length of 100cm and a width of 60cm. One bag weighs 10 kg. After the bag is tied up, soak it in lime water, turn it over and over again to make the lime water soak into the bag, and finally press stones on the bag. or a heavy object such as a brick so that the bag is completely submerged in the lime water. Turn the bag once a day and stir the lime water with a wooden stick. After soaking for 10 days, take out the seeds, rinse them with clean water repeatedly, drip dry water, soak them in 200mg / L gibberellin for 6 hours, spread the seeds evenly on the sand bed, and press them down with wooden boards to make 1 / 4~1 / 3 of the seeds Trapped in the sand, do not cover the sand, do not shade, keep the sand moist, and water once in t...

Abstract

The invention discloses a teak low-chipper sprout-promotion rapid-propagation seed-growing method. Seeds are soaked by lime water and gibberellin and then sowed, then seedlings are transplanted into a first nutrition substance container to cultivate mother seedlings to a stage when leaves are mutually overlapped, then the seedlings are graded and arranged according to certain planting space, when ground diameter of the mother seedlings is 0.4-0.8cm, the mother seedlings are planted into a plastic pot with a bottom support to be bred, wherein the mother seedlings are not separated from container cups, and second nutrition substance is arranged in the plastic pot. After 10-15 days, the mother seedlings are cut at a position where base parts of the mother seedling are close to the ground to promote sprouting, collecting cuttings and arranging the cuttings in a container cup provided with third nutrition substances in cottage mode, growing seedlings on an elevated seedling bed in a plastic greenhouse, controlling air temperature and relative humidity of a cottage bed by utilizing a greenhouse temperature and moisture adjuster, and thus obtaining teak container cottage seedlings. By means of the teak low-chipper sprout-promotion rapid-propagation seed-growing method, cottage branches are short, interval time of cutting collection is shortened, breeding efficiency is improved, field condition requirements of nursery gardens are not strict, management is convenient, cutting quality is easy to control, cottage survive rate is high, and economic benefit is good.

Description

technical field [0001] The invention belongs to the technical field of asexual rapid propagation of plants, and relates to a teak low-cutting method for promoting germination and rapid propagation of seedlings. Background technique [0002] Teak (Tectona grandi s L.F.) is a deciduous or semi-deciduous broad-leaved tree belonging to the genus Tectona of the Verbenaceae (Vcrbenaceae). Teak heartwood has a large proportion and is dark brown. It is extremely resistant to insects, corrosion, water, and fire. It will not warp or crack under the condition of obvious changes in dryness and humidity. It is easy to process, beautiful in pattern, and has a wide range of uses. Veneer and plywood are used in shipbuilding, vehicles, sleepers, poles, instrument boxes, piano and organ shells, etc., and are recognized as one of the highest quality and precious woods in the world. There is no teak natural forest distribution in my country, and the artificial forest area is small, so a large ...
