Abstract

The invention discloses a method for promoting germination of cinnamon seed. The method comprises the procedures of seed collection, seed pretreatment, pregermination by sand storage and breeding management. The method particularly comprises the following steps of: collecting ripe cinnamon seed, sealing the ripe cinnamon seed, rinsing and fertilizing the seed, then soaking the seed by clean water and gibberellin in sequence, carrying out pregermination by sand storage on the processed seed, and obtaining the germinant seed by breeding management. By the method, the germination rate of the cinnamon seed is improved; the gibberellin is adopted to break through the dormant period of the cinnamon seed; and the germination period of the seed is obviously shortened. The method is simple to operate and low in cost, can promote the cinnamon seed to germinate rapidly, uniformly and efficiently, and has good economical benefit and social benefit.

Description

A kind of method for promoting the germination of cinnamon seeds

technical field

The invention relates to a method for accelerating germination of seeds, in particular to a method for promoting the germination of cinnamon seeds.

Background technique

Cinnamon (Cinnamomum cassia Presl) is an evergreen tree of the family Lauraceae (Cinnamomum). It is one of the characteristic woody spice tree species in southern my country. It combines spices, medicinal materials and materials. The whole body of the cinnamon tree is a treasure. It is regarded as a treasure in medicine, and is often called "ginseng, antler, swallow, and osmanthus" together with ginseng, antler, and bird's nest. In addition, cinnamon is also widely used as a precious spice in the food industry and light chemical industry. The branches and leaves of cinnamon can be used for steaming oil, and cinnamon oil can be directly used to prepare food and beverages, and can also be used to synthesize various high-grade spices, and is also widely used in the pharmaceutical industry. Cinnamon wood is excellent in material, fine in structure, not easy to crack after drying, and has little wood deformation. It is one of the high-quality boards and can be used to make high-end furniture and develop various high-end wood products.

The methods of cinnamon propagation include seed propagation, sprouting, layering and cuttings, etc., and seed propagation is the main method. Cinnamon seeds have high oil content, so they cannot be stored dry after harvesting, and they tend to lose their germination power after drying, and the newly harvested cinnamon seeds are in a dormant state, so direct seeding is slow to germinate. tidy.

Contents of the invention

The object of the present invention is to aim at the deficiencies of the prior art, and provide a method for promoting the germination of cinnamon seeds in order to rapidly and effectively improve the germination rate and germination speed of cinnamon seeds.

The present invention is achieved through the following technical solutions:

A method for promoting the germination of cinnamon seeds, which includes the procedures of seed collection, seed pretreatment, sand storage for germination acceleration, and breeding management and protection. After collecting mature cinnamon fruits and sealing them, they are washed and disinfected, and then washed with water and red Soak the seeds with mymycin, then store the treated seeds in sand to accelerate germination, and obtain germinated seeds through breeding management and protection. The main operation steps are as follows:

(1) Seed collection: collect mature cinnamon fruit and put it in a closed container for 1-2 days;

(2) Pre-treatment of seeds:

① Seed washing: wash the sealed cinnamon fruit with water, remove the outer fleshy peel, and remove impurities or shriveled seeds;

② Disinfection: Soak the washed cinnamon seeds in 0.3% potassium permanganate solution for 25-35 minutes;

③ Seed soaking: Soak the sterilized cinnamon seeds in water for 2-3 days to obtain imbibed seeds;

④ Gibberellin treatment: Soak the imbibed cinnamon seeds in 100-400mg/L gibberellin solution for 1 day;

(3) Sand storage germination: first put the cleaned river sand in an oven at 110-130°C to dry, and let it cool down to room temperature naturally, then put the sand into a flower pot, moisten the sand with clean water, and spread the cinnamon seeds evenly. Sow on the sand, place the flower pot in the nursery, cover with a thin layer of clean fine sand, and cover with plastic film to keep moisture;

(4) Breeding management and protection: The cultivated cinnamon seeds are regularly sprayed with water or fungicides with a sprayer.

In the method for promoting the germination of cassia cinnamon seeds described above, in the step of sand storage for accelerating germination, the thickness of the thin layer of clean fine sand covered is 0.7-1.0 cm.

A kind of method for promoting the germination of cassia cinnamon seeds described above, regular spraying is that 1‰ carbendazim solution or chlorothalonazim solution is sterilized in the flowerpot of breeding bed with bactericide, sprays once every 5 days; Spray water once in the pots of the beds.

Compared with the prior art, the present invention has the following advantages:

1, a kind of method of promoting the germination of cinnamon seeds of the present invention, process cinnamon seeds with gibberellin, break the dormancy period of seeds, impel cinnamon seeds to germinate fast and neatly.

2, a kind of method for promoting the germination of cassia cinnamon seeds of the present invention, seeds are sterilized with potassium permanganate, and river sand is processed in the mode of high-temperature sterilization, effectively prevented cassia cinnamon seeds from producing mildew, improved the quality of cassia cinnamon seeds Germination rate.

3, a kind of method for promoting the germination of cassia cinnamon seeds of the present invention, the flowerpot that sand storage seed is housed is placed in the nursery, covers with plastic film, and regularly sprinkling water and carry out moisturizing, allows seed to germinate under natural state, is suitable for production.

4. A method for promoting the germination of cinnamon seeds of the present invention has simple process operation, low cost, convenient operation, and is suitable for popularization.
