Problems solved by technology

This kind of processing mode requires multiple equipments and the coordination and cooperation of multiple people. Human factors have a significant impact on the quality of the coated seeds, and the seeds are easily damaged during the processing process; Unreasonable, poor adaptability, unable to guarantee germination rate; backward processing machinery and technology, unsatisfactory one-time molding effect, unsatisfactory granulation shape, and poor granulation performance
Moreover, the prepared pelletized tobacco seeds need to use adhesives due to their low strength, which leads to higher production costs and is fragile during drying, packaging and transportation of the coated seeds.

experiment example 1

[0071] The coated finished tobacco seeds obtained in Example 1 were used as experimental materials, and the coated pelleted seeds of Comparative Example 1 were used as controls. The seeds after pelleting were carried out germination experiment respectively, and the process is as follows:

[0072] 1. Put 2 layers of wet filter paper in a petri dish, place 100 pelleted seeds evenly on each petri dish and cover it, and germinate the pelleted seeds at 25°C and 12h / 12h light / dark conditions, keep The filter paper is moist.

[0073] 2. Record the number of germinated seeds every day from the 3rd day (germinated when the radicle length is greater than or equal to the seed length), and record continuously for 14 days until the end of germination.

[0074] 3. After germination, calculate the germination potential and germination rate of the pelleted seeds.

[0075] Germination potential (%) = (Number of seeds normally germinated in 7 days / Number of seeds tested) × 100%,

[0076] Ger...

Abstract

The invention discloses an efficient pelleting method of tobacco seeds. The method comprises the following steps: removing sundries and undesirable seeds from the seeds, and then performing winnowingand sieving to obtain pre-coating seeds; preparing a powder for nucleation coating and a powder for pelletizing coating; preparing pigment slurry; adding a variety of minerals into water and performing uniform mixing to obtain a mineral nutrient solution; putting the powder for nucleation coating, the mineral nutrient solution, and the pre-coating seeds into a seed coating and pelletizing apparatus to perform pelleting treatment, and completing pelleting treatment until a diameter is 0.7-0.9 mm; putting the powder for pelletizing coating, the mineral nutrient solution, primary pelleted seeds into the seed coating and pelletizing apparatus to perform pelleting treatment, and completing pelleting treatment until a diameter is 1.6-1.8 mm; and sieving out the coated seeds after pelleting witha particle size of 1.7-1.8 mm, performing polishing, performing coloring with the pigment slurry, and performing drying to obtain a coated seed finished product. The coating and pelletizing process ofthe method does not require the use of a binder, the cost is low, the pelletizing process of the tobacco seeds is formed at a time, the influence of human factors is eliminated, and the pelletized seeds have high strength.

Description

technical field [0001] The invention belongs to the technical field of seed treatment, and in particular relates to a high-efficiency pelletizing method for tobacco seeds with simple operation, one-time molding in the pelletizing process, no binder, high pelletized seed strength and low production cost. Background technique [0002] Seed pelleting technology is a specialized technology in seed processing. It is a high-tech suitable for agricultural development developed on the basis of seed film coating. It uses nutrients that are beneficial to seed germination and The filler, which has no side effects on the seeds, is evenly wrapped on the outer surface of the seeds after being fully mixed, so that the shape of the seeds changes from irregular and uneven to uniform seeds of uniform size and regular shape, which is convenient for manual or mechanized precision Seed processing techniques for sowing. [0003] Small seed pelleting technology originated in the United States in ...
