Abstract

The invention discloses a teak seed presprouting method. The teak seed presprouting method comprises the following steps: refrigerating the selected seeds at 4 DEG C below zero for 24 hours; soaking the seeds in 10 percent lime water for sterilization; removing fiber corpus cavernosum mechanically; baking the seeds at 50 to 60 DEG C for 36 hours; soaking the seeds in water for 10 hours; drying the seeds in the air for 5 to 10 hours; spraying a biotin for pregermination; and sowing the seeds 24 hours later. The teak seed presprouting method can realize the quick, abundant and even budding of the teak seeds; one seed can have a plurality of buds; and the teak seedlings have high resistance to coldness and drought and high regional adaptability.

Description

A kind of method for accelerating germination of Tectona grandis seed

Technical field

The present invention relates to plant the method for pre-treatment seed.Be specifically related to the germination accelerating method of teak seed.

Background technology

The Tectona deciduous species, seeds are rare, and it is unusual to bloom, can fresh air, improve environment.Because the golden yellow texture of the beauty of its uniqueness, more because it is uniquely to have natural oil and keep moisture avoiding crooked, but and insect-pest, so be widely used for shipbuilding, building, door and window garden, furniture, floor, wall coverings, art sculpture and handicraft.Corroding and fire-proof function because teak has the special chemical substance of bearing, is to be used to bear burn into to prevent the desert drying in the industry of oil field, and insulation causes the industrial timber of explosion danger because of electric leakage.

In recent years, teak plantation development is very fast, and the nursery stock demand is big, but because teak seed kind bony nodule matter, be rich in tannin, felted fine hair is arranged, be difficult for water-permeable and air permeable, the relatively difficulty of germinateing, germination process often continues the several months, even surpasses 1 year, and time-consuming taking a lot of work influences breeding and afforestation.Therefore, how carrying out vernalization and handle, is urgent problem in the current development teak afforestation.Present growing seedlings all is to adopt the nature seedling method, directly the seed that dries broadcast into Miao Dizhong, that this method is sprouted less, sprouted is uneven, can not cold-resistant drought resisting and region adaptability not strong.

Summary of the invention

The purpose of this invention is to provide the germination accelerating method that can further improve bud ratio, cold-resistant drought resisting of teak seedling and region adaptability are strengthened.

For achieving the above object, technical scheme of the present invention may further comprise the steps:

1. seed selection;

2. freezing: that the seed of choosing is freezing 24 hours at-4 ℃;

3. sterilization: in 10% limewash, soak sterilization in 24 hours;

4. peeling: machinery removes the fiber sponge body;

5. baking: 50-60 ℃ was toasted 36 hours;

6. bubble is planted: soaked 10 hours in the water;

7. dry: 5-10 hour;

8. vernalization: spray vitamin h vernalization;

9. sowing: can sow after 24 hours.

Seed can improve its cold-resistant drought resistance after passing through freezing and high-temperature baking, and region adaptability strengthens.After the baking, seed shrinks, and expands in the soaked process, dries moisture, sprays vitamin h vernalization.

Implement teak seed of the present invention sprout soon, sprout many, and polygerm, neat, the teak seedling of sprouting cold-resistant drought-enduring, region adaptability is strong.

Embodiment

Earlier that 100 grain-by-grain seed selections are good seed-4 ℃ freezing 24 hours, 10% limewash soak 24 hours sterilization, machinery go to soak in 36 hours high temperature of fiber sponge body, 50-60 ℃ baking, the water 10 hours, dry 5-10 hour, spray vitamin h vernalization, can sow after 24 hours.Germinateed in 10 days in advance than growing seedlings naturally, germination rate is higher than 50%, and a polygerm person is higher than 40%.

Claims (1)

1. method for accelerating germination of Tectona grandis seed is characterized in that may further comprise the steps:

1. seed selection;

2. freezing: that the seed of choosing is freezing 24 hours at-4 ℃;

3. sterilization: in 10% limewash, soak sterilization in 24 hours;

4. dejacketing: machinery removes the fiber sponge body;

5. baking: 50-60 ℃ was toasted 36 hours;

6. bubble is planted: soaked 10 hours in the water;

7. dry: 5-10 hour;

8. vernalization: spray vitamin h vernalization;

9. sowing: can sow after 24 hours.
