Problems solved by technology

[0004] Existing tobacco seeds need to be stored in a warehouse for a period of time after seed priming and processing, and can be provided to various tobacco areas for tobacco leaf production and use after about 6 months. The impact of priming under different conditions on seed storage is currently unknown in the industry. There are no relevant studies and reports

Embodiment 1

[0054] Embodiment 1 - the bare tobacco species is MSK326

[0055] A method for improving the vigor of tobacco seeds based on seed priming, comprising the following steps:

[0056] 1) Seed soaking: Put the bare tobacco seeds in water at a ratio of 1kg:4L, and soak for 3 hours at room temperature; the bare tobacco seeds are MSK326;

[0057] 2) Disinfection: soak the soaked seeds in a copper sulfate solution with a concentration of 6g / L for 20 minutes and take out the seeds floating on the surface of the solution. After the disinfection is completed, wash the remaining seeds with clean water;

[0058] 3) Initiation: put the sterilized seeds into 0.05g / l gibberellin solution, initiate under full light conditions, the initiation temperature is 15-25°C, and the initiation time is 12-48h, then take out the seeds and clean them;

[0059] 4) Drying: Spread the induced seeds evenly on the baking tray, air-dry naturally until the moisture on the surface of the seeds is dry, then heat to...

Abstract

The invention discloses a method for improving vitality of tobacco seeds on the basis of seed priming. The method comprises the following steps: 1) soaking seeds: putting tobacco naked seeds into water according to the proportion of 1kg:(2-6)L, and ventilating and soaking under the condition of normal temperature for 2.5 to 3.5 hours; 2) disinfecting: putting the soaked seeds into a copper sulfatesolution with the concentration of 4 to 8 g / L, soaking for 10 to 30 minutes, taking on the seeds which float on the surface of the solution, and after disinfecting, completely cleaning the remained seeds with clean water; 3) initiating: putting the disinfected seeds into an initiator, initiating under the condition of full illumination at the initiating temperature of 15 to 25 DEG C for 12 to 48hours, taking out the seeds and completely cleaning; and 4) drying. By the method, the tobacco seeds are subjected to normalized seed soaking, disinfecting, initiating, drying and storage treatment, so that the vitality of the tobacco seeds is effectively improved, the tobacco seeds can be germinated rapidly under the stress conditions of low temperature and the like, the germination rate is increased and seed dormancy can be relieved.

Description

technical field [0001] The invention belongs to the technical field of seed treatment, and in particular relates to a method for effectively improving the vigor of tobacco seeds. Background technique [0002] Seed priming, also known as osmotic adjustment, is a seed treatment technology that controls the slow water absorption and gradual drying of seeds. It has been applied to vegetable crops such as cypress, eggplant, cabbage, pepper, etc., and grain as seeds such as wheat, barley, and corn. , oil crops such as rapeseed, peanut, soybean and other seeds, after priming treatment, the seeds have enhanced vitality, enhanced stress resistance, low temperature resistance, slow imbibition damage, fast and uniform emergence, high seedling rate, thereby indirectly saving seeds and reducing costs ,Improve efficiency. At present, the commonly used methods of seed priming in China include liquid priming, solid matrix priming, roller priming and biological priming. Liquid initiation u...
