Embodiment 1

[0042] A nano-coated pelleted seed, comprising seed, a nano layer wrapped around the seed and a pelleted layer wrapped around the nano layer from the inside to the outside; the thickness of the nano layer is 1-10nm, and the thickness of the pelleted layer is 1-3mm; seeds are tobacco seeds.

[0043] The material used for the preparation of the nano-layer is calcium peroxide nano-particles with a particle size of 0.1-1 nm;

Embodiment 2

[0045] Basically the same as Example 1, the difference is: the thickness of the nano layer is 8nm, and the thickness of the pelletized layer is 3mm;

Embodiment 3

[0047] It is basically the same as in Example 1, except that the material used for the preparation of the nano-layer is Cr nanoparticles with a particle size of 2-8nm;

Abstract

The invention discloses a nano-coated pelletized seed and a preparation method thereof. A nano-coated pelleted seed comprises seeds, a nano-layer wrapped around the seed and a protective layer wrapped around the nano-layer from the inside to the outside, and the protective layer is a coating layer, a coating layer or a pelletized layer. The nano-coated pelletized seeds of the present invention have a round appearance, a tight coating layer and good solubility; compared with the prior art, the germination rate, germination potential and bacon growth of the seeds are all significantly improved; the use of nanoparticles The use of fertilizers is significantly reduced, and the vigor of the seeds is significantly improved; the deformity rate of the seedlings is low, the drought resistance is strong, the seeds germinate and emerge quickly, uniform, good growth, high vitality, and strong drought resistance; effectively solve the problem of excessive use of chemicals and fertilizers question.

Description

technical field [0001] The invention relates to a nano-coated pelletized seed and a preparation method thereof, belonging to the field of pelletized seeds. Background technique [0002] Seeds are the basic material for agricultural production and the carrier of fine varieties. Therefore, the quality of seeds is very important for agricultural production. For some small seeds, such as: vegetable seeds, grass seeds, forest tree seeds, etc., there is a problem that the number of sows is large and difficult to control in live broadcasting. In order to improve the quality and efficiency of sowing, seed pelleting technology is widely used in the processing of small seeds. Seed pelletization is a seed layered granulation technology with seeds as the core, clay and talcum powder as the main auxiliary materials, and pesticides, fungicides, plant growth regulators and other agents. For a long time, problems such as low seed vigor and excessive use of chemicals and fertilizers have ...
