Embodiment 1

[0022] Put the seeds in the seed drying and removing bracting machine, set the temperature to 30°C, then start the drum and the stirring paddle, blow air, after drying for 2 days, blow the natural wind for 0.1h, then increase the speed of the stirring paddle to hammer the seeds, so that Seed bud breaks away from seed. Use a mesh screen with a mesh size of 1.1 cm to sieve the seeds and seed buds with a diameter of less than 1.1 cm to obtain seeds for sowing, and store the seeds in a cloth bag and store them in a ventilated and dry place. On March 10, soak the seeds in 0.2% potassium permanganate solution for 24 hours, remove the seeds, rinse them with clean water, spread them on the germination bed, press the seeds flat into the soil, cover with fine soil or For river sand, it is advisable not to see the seeds, and finally water thoroughly. Build a 50cm-high arch shed to cover the film for heat preservation, and install a geothermal heating system in the germination bed. From ...

Embodiment 2

[0024] Put the seeds in the seed drying and removing budding machine, set the temperature to 35°C, then start the drum and the stirring paddle, blow air, after drying for 1 day, blow the natural wind for 0.5h, then increase the speed of the stirring paddle to hammer the seeds until Seed bud breaks away from seed. Use a mesh screen with a mesh size of 1.1 cm to sieve the seeds and seed buds with a diameter of less than 1.1 cm to obtain seeds for sowing, and store the seeds in a cloth bag and store them in a ventilated and dry place. On April 10, soak the seeds in 0.3% potassium permanganate solution for 20 hours, remove the seeds, rinse them with clean water, spread them on the germination bed, press the seeds flat into the soil, cover with fine soil or For river sand, it is advisable not to see the seeds, and finally water thoroughly. Build a 50cm-high arch shed to cover the film for heat preservation, and install a geothermal heating system in the germination bed. From 11 to...

Embodiment 3

[0026] Put the seeds in the seed drying and debracting machine, set the temperature at 33°C, then start the drum and the stirring paddle, and blow the air. After drying for 1.5 days, blow the natural wind for 0.2 hours, and then increase the speed of the stirring paddle to hammer the seeds. Break the buds and break away from the seeds. Use a mesh screen with a mesh size of 1.1 cm to sieve the seeds and seed buds with a diameter of less than 1.1 cm to obtain seeds for sowing, and store the seeds in a cloth bag and store them in a ventilated and dry place. On May 10, soak the seeds in 0.4% potassium permanganate solution for 22 hours, remove the seeds, rinse them with clean water, spread them on the germination bed, press the seeds flat into the soil, cover with fine soil or river For sand, it is advisable not to see the seeds, and finally water thoroughly. Water once a day in the evening on sunny days. When some seeds are exposed to the soil or sand, cover them with fine soil ...

Abstract

The invention discloses a teakwood seed treatment germination method. The method comprises the processes of removing seed buds, screening seeds, soaking seeds and performing seed germination. The method comprises the following steps: drying the teakwood seeds and removing the teakwood seed buds in a seed drying and bud removing machine; selecting the seeds by using a screen; removing small seeds; soaking the seeds by using medicament liquid; and sowing the seeds on a germination bed for germinating. Compared with a conventional method of exposing the seeds to the sun, removing the seed buds artificially and not selecting seeds, the germination method according to the invention has the advantage that the labor intensity is reduced, and the utilization rate of the germination bed is improved; the seeds are soaked by using a potassium permanganate solution, and compared with the germination method of soaking the seeds by lime slurry, and dipping and drying, the germination method according to the invention has the advantage that the workload is lightened; compared with a gibberellin soaking method, the germination method according to the invention has the advantage that the production cost is reduced; compared with a sand bed exposure sowing method, the germination method according to the invention has the advantage that the germination rate and the germination index of the seeds are improved; the seedling transplanting time can be advanced to April by using a geothermal heating system, and the growth time before the seedling leaves a nursery garden is prolonged, so that the seeding quality is improved, and favorable conditions are created for breeding a large number of rare tree species; therefore, the method has a good economic benefit and a good social benefit.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and relates to a teak seed treatment and acceleration germination method. Background technique [0002] Teak (Tectona grandis L.F.) is a large semi-deciduous tree belonging to the Verbenaceae teak family. The heartwood of teak has a large proportion and is dark brown. It is extremely resistant to insects, decay, water, and fire. It is not cracked, easy to process, has a wide range of uses, and has beautiful patterns. It is known as one of the most important tropical timber species in the world. It is listed as the most common plantation tree species in the world along with pine, eucalyptus and poplar. It is also one of the most popular hardwood species in the international market, and the price in the international timber market is very high. [0003] The Institute of Tropical Forestry of the Chinese Academy of Forestry has long been engaged in systematic research on teak introduction, im...
