Problems solved by technology

Relevant domestic units have started to study this since 2000, such as Chinese patent (03135483.1) "A Production Method for Tobacco Germination-type Coated and Pilled Seeds", this patent has only solved the problem of the coating of tobacco seeds. Chemical technology, but its germination technology still adopts general physical method

Embodiment 1

[0021] Embodiment one: get gibberellin 7.5 grams, naphthalene acetic acid 0.075 grams, indole acetic acid 0.075 grams, a small amount of ethanol (its weight is ignored in solution), pure water 92.35 grams, gibberellin, naphthalene acetic acid, indole acetic acid Dissolve with a small amount of ethanol successively, then add one by one successively and completely dissolve in 92.35 grams of pure water, which becomes the tobacco seed initiator stock solution of the present invention, and bottling is the finished product.

[0022] When in use, take an appropriate amount of tobacco seed initiator and dilute it 1000 times to obtain the seed initiation concentration. Soak the tobacco seeds in the diluted initiator. The weight ratio of the seed to the initiator is preferably 1:1.5, and the temperature is controlled at 25°C ± 1°C, after 24 hours of initiation, the seeds are separated from the water, and the seeds are dried back in a special oven, the temperature is set at 40°C ± 5°C, an...

Embodiment 2

[0023] Embodiment two: get gibberellin 5.0 grams, naphthalene acetic acid 0.05 grams, indole acetic acid 0.05 grams, a small amount of ethanol (its weight is neglected in solution), pure water 94.9 grams, its preparation method and use are identical with embodiment one.

Embodiment 3

[0024] Embodiment three: get gibberellin 10 grams, naphthalene acetic acid 0.1 gram, indole acetic acid 0.1 gram, a small amount of ethanol (its weight is neglected in solution), pure water 89.8 grams, its preparation method and use are identical with embodiment one.

[0025] The tobacco seed initiator of the present invention is used for initiation and activation treatment before tobacco seed coating pelletization, and is suitable for initiation pretreatment before tobacco seed coating in tobacco planting areas all over the country. Tobacco seed initiator that has the advantages of sex and germination, improves the uniformity of seedling emergence, shortens the time of seedling emergence, and promotes the obvious improvement of the quality of tobacco seedlings.

Abstract

The invention discloses a tobacco seed primer, which relates to the technical field of crop seeds. The tobacco seed primer is prepared by dissolving gibberellin, naphthalene acetic acid and indoleacetic acid in water, has the characteristics of obviously strengthening the self-stress resistance and the germination advantage of tobacco seeds, improving the uniformity of seedling emergence, shortening seedling emergence time, promoting the obvious improvement of the quality of tobacco seedlings and so on, is applicable to the priming treatment of tobacco seeds in tobacco planting areas across the country before the coating, and is the tobacco seed primer with better priming effect.

Description

Technical field [0001] The invention relates to the technical field of crop seeds, in particular to an initiator for triggering and activating treatment of tobacco seeds. Background technique [0002] In production, tobacco seeds are usually sown after being coated and pelletized. Before the promotion of coating and pelletizing technology, flue-cured tobacco seedlings are mostly sterilized, soaked, germinated and then sown in the conventional way. Seed technology has made great progress, but there are common problems such as slow emergence of seedlings, uneven growth of tobacco seedlings, and low seedling rate in coated seeds that have not been primed, especially in winter seedling cultivation areas such as Hunan, Fujian, and Guangdong. This phenomenon is more common. Therefore, combining seed priming and coating to develop tobacco priming-coated species has become a new topic in the field of seed technology. At the end of the last century, the United States, Brazil and ot...
