Embodiment 1

[0043] Example 1 Preparation of tobacco pelleted seeds

[0044] Pour 10g of tobacco seeds into the coating machine.

[0045] Granulation: Take 200mg of rhodamine B into distilled water to prepare a rhodamine B aqueous solution with a concentration of 2.0mg / ml, first spray 7.5ml of rhodamine B aqueous solution to moisten the surface of the seeds, add 0.5g of bentonite and stir continuously to make it Wrap it on the surface of the seeds, repeat the above steps 3-5 times to make the seeds form tiny pellets; then add 2-5g of bentonite to the pelleted seeds each time, spray the 1.0% carboxymethyl cellulose solution with constant stirring , Repeat several times to increase the particle size of the pelleted seeds to 1.00mm-1.25mm;

[0046] Pelletizing: Mix 21g magnetic powder and 399g talc powder uniformly to obtain a mixture of talc powder and magnetic powder total mass 5% of the magnetic powder content, add 2g-5g talc powder and magnetic powder mixture to the pelletized seeds formed by...

Embodiment 2

[0050] Example 2 Preparation of tobacco pelleted seeds

[0051] The process of Example 1 is repeated, the only difference is that in Example 1, 33.6 g of magnetic powder and 386.4 g of talc powder are mixed uniformly during the pelletizing step to obtain a mixture of magnetic powder content of 8% of the total mass of talc powder and magnetic powder.

Embodiment 3

[0052] Example 3 Germination of tobacco pelleted seeds

[0053] Prepare a certain amount of control pelleted seeds. The specific preparation method is similar to that of Example 1. The difference is that in the granulation step, the rhodamine B solution is replaced with distilled water for spraying, and the magnetic powder is not added in the pelletizing step to prepare the pellets. Chemical seeds, the control is represented by CK. The tobacco pelletized seeds prepared in Example 1-2 and the control pelletized seeds were subjected to a paper germination test, and the seed germination and seedling physiological indexes were measured.

[0054] Among them, the methods for determining seed germination and seedling physiological indicators are as follows:

[0055] (1) Seed germination and seedling index

[0056] The pelletized seeds were placed in a petri dish of 9 cm in diameter with three layers of moisture-absorbing filter paper. Each treatment was repeated 3 times, and 100 pelleted...

Abstract

The invention provides a method for producing a fluorescent magnetic powder dual anti-counterfeiting pelleted seed, which comprises the steps of coating a raw seed with a first seed coating to form a pelletized seed, then mixing a second seed coating and a certain amount of magnetic powder and coating the pelletized seed with the mixture to form the pelleted seed. The pelleted seed which is obtained by the method has a two-layer structure, the inner layer structure which is close to the raw seed contains a fluorescence color agent, the outer layer structure contains magnetic powder, and the pelleted seed can be identified through magnetic materials and exciting light having a certain wavelength. The method has the advantages that simple adjustment is performed on the basis that the original pelleting process flow of the seed is not changed, update of devices is not required, and the anti-counterfeiting cost is cheap. The pelleted seed having a dual anti-counterfeiting function has no difference in appearance with common pelleted seeds and the pelleted seed having a dual anti-counterfeiting function can only be identified through specific detection methods. The method provides a simple and reliable anti-counterfeiting technology for seeds and enhances the protection of seed quality and benefits of seed companies and seed users.

Description

Technical field [0001] The invention relates to a seed anti-counterfeiting technology, in particular to a preparation method of fluorescent magnetic powder double anti-counterfeiting pelletized seeds, and also relates to anti-counterfeiting pelletized seeds obtained by the method and a method for identifying the anti-counterfeiting seeds. Background technique [0002] Seeds occupies an important position in the national economy, but seeds are often counterfeited by criminals, which brings great harm to agricultural production and farmers. Regarding seed anti-counterfeiting, anti-counterfeiting packaging technologies are currently commonly used in the industry. Seed packaging is the direct carrier of seed sales, so seed packaging anti-counterfeiting has naturally become a more direct and effective solution for seed companies to combat counterfeiting, maintain the normal order of the seed market, and protect their own interests and legitimate rights and interests. However, the con...
