Cold-humid adversity resisting tobacco coated seed and preparation method thereof

Abstract

The invention discloses a cold-humid adversity resisting tobacco coated seed and a preparation method thereof. Before being subjected to coating and pelleting, the tobacco seed is initiated by using mixed solution consisting of 5 to 10g / L urea hydrogen peroxide and 50 to 100mg / L gibberellin; and when coating and pelleting is performed, 10.0 to 20.0 percent calcium peroxide is added into a seed coating agent. The cold-humid adversity resisting tobacco coated seed prepared by the invention has the advantages of high seed activity, short sprouting time, high rate of emergence in the fame, uniform emergence of seedlings, high resistance to low temperature stress and hyproxia stress, and the like, and has excellent application prospect in the tobacco production.

Description

technical field

[0001] The invention belongs to the technical field of tobacco seed coating processing, and in particular relates to a cold-humid stress-resistant tobacco coated seed which is especially suitable for a cold-humid seedling raising environment. At the same time, the invention also relates to a preparation method of the cold-humid stress-resistant tobacco coated seeds. Background technique

[0002] Tobacco floating seedling cultivation is an advanced seedling raising technology in tobacco leaf production. It has high production efficiency and neat growth of tobacco seedlings, which is suitable for specialized and large-scale production of tobacco leaves. Since 1996, along with the rapid development of tobacco leaf production in my country, the floating seedling raising technology of tobacco has been popularized very rapidly in tobacco leaf production.

[0003] To facilitate sowing, tobacco-coated seeds are generally used in tobacco leaf production. Early tobac...

Examples

Embodiment 1

[0016] Take 100g of MS Yunyan 87 seeds, put them into 10kg of a mixed solution of 10g / L urea peroxide and 100mg / L gibberellin, stir constantly, and trigger under light at 25°C for 24h. After the priming is finished, the seeds are washed with clear water, and dried back at room temperature to a water content of 4.0-7.0%, and then used for later use.

[0017] During seed coating and pilling, add 10.0% calcium peroxide to the seed coating agent (including GTG powder, bentonite, talcum powder, bactericide, micro-fertilizer, etc.), and mix evenly with a mixer. Add the induced seeds to the coating machine, spray the adhesive to moisten the seeds, add the seed coating agent to coat and nucleate, and repeat this alternately, double the seed pellets to a particle size of 1.6-1.8mm, and then shape the seeds, and then The seed coating agent is added into the coating machine step by step, the shaped pelleted seeds are polished, and then an appropriate amount of pigment is added for dyeing...

Embodiment 2

[0019] Repeat Example 1, with the following differences: a mixed solution of 8g / L urea peroxide and 80mg / L gibberellin was used to trigger 30h.

Embodiment 3

[0021] Repeat Example 1, with the following differences: a mixed solution of 5g / L urea peroxide and 50mg / L gibberellin was used to trigger 30h.
