Embodiment 1

[0039] The present embodiment provides a kind of coated seed of the mustard, and the seed coating composition that it uses is as follows:

[0040] Attapulgite 4g, sandy soil 178g, water-absorbing resin 0.5g, chitosan solution 80g. Wherein the mass fraction of chitosan in the chitosan solution is 2%. The sand contains water-soluble fertilizer with a mass fraction of 3%. The water-absorbing resin is sodium polyacrylate. The weight of 1,000 grains of bare seeds of S. mustard is 20g.

[0041] The preparation process of this coated seed is as follows:

[0042] Chitosan solution is mixed with 10g naked seed, then the mixture of attapulgite, sandy soil, water-absorbing resin is mixed with the naked seed wetted by chitosan solution, until the naked seed is coated into a diameter of 5 mm. Can.

Embodiment 2

[0044] The present embodiment provides a kind of coated seed of Chickweed, and the seed coating composition that it uses is as follows:

[0045] Attapulgite 10g, sand 97g, water-absorbing resin 2.5g, salicylic acid 0.003g, yttrium carbonate 0.08g, chitosan solution 60g. Wherein the mass fraction of chitosan in the chitosan solution is 5%. The sandy soil contains 7% controlled-release fertilizer. The water-absorbing resin is sodium polyacrylate grafted starch. The 1000-grain weight of naked seeds of Niuzhizi is 2.8g.

[0046] The preparation process of this coated seed is as follows:

[0047] 2g bare seeds are rotated at a speed of 1000 rpm. During the rotation of crop seeds, chitosan solution is first added, and then a mixture of water-absorbing resin, attapulgite, sand, salicylic acid, and yttrium carbonate is added. The two feeding steps were repeated at intervals of 7 seconds until the naked seeds were coated into coated seeds with a diameter of 3.5 mm. The compounding...

Embodiment 3

[0049] The present embodiment provides a kind of coated seed of camel thorn, and the seed coating composition that it uses is as follows:

[0050] Attapulgite 2g, sandy soil 89g, water absorbent resin 0.8g, salicylic acid 0.001g, cerium carbonate 0.05g, chitosan solution 45g. Wherein the mass fraction of chitosan in the chitosan solution is 4%. The sand contains 6% slow-release fertilizer by mass fraction. The water-absorbing resin is sodium polyacrylate grafted cellulose. The thousand-grain weight of camel thorn bare seed is 3g.

[0051] The preparation process of this coated seed is as follows:

[0052] 3g bare seeds are rotated at a speed of 3000 rpm. During the rotation of crop seeds, chitosan solution is first added, and then a mixture of water-absorbing resin, attapulgite, sand, salicylic acid, and cerium carbonate is added. The two feeding steps were repeated every 14 seconds until the naked seeds were coated into coated seeds with a diameter of 3 mm. The compoundi...

Abstract

The invention provides a seed coating agent and a coated seed, and relates to the technical field of seed treatment. The seed coating agent is mainly prepared from raw materials including, by weight,2-10 parts of attapulgite, 89-97 parts of sandy soil, 0.5-2.5 parts of water absorbent resin and 40-60 parts of chitosan solution. The chitosan solution comprises, by weight, 2-5% of chitosan, and thesandy soil comprises, by weight, 5-10% of fertilizers. The seed coating agent and the coated seed have the advantages that the attapulgite, the sandy soil and the water absorbent resin have appropriate weight proportions, and accordingly the seed coating agent can wrap small seeds and even can wrap seeds with the low thousand-seed weights of 0.2 g; the chitosan solution and the attapulgite are mixed with each other, and accordingly the seed coating agent can be solidified on the surfaces of the seeds; the proportions of the various raw materials are appropriately selected, accordingly, the drought resistance of the seeds can be greatly improved by the seed coating agent in growth procedures, the germination and growth ability of the seeds can be guaranteed, and the establishment success rate of crops can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a seed coating agent and coated seeds. Background technique [0002] In recent years, the problems of vegetation degradation and endangered species in the arid region of Northwest China have become increasingly serious. Desertification control, vegetation restoration and plant protection have become important tasks for local and even national ecological construction. Native plants have the functions of water and soil conservation, windbreak and sand fixation, and play an important role in the sustainable development of grassland animal husbandry. Ecological grass species such as Amansia awnica and Niuzhizi are important high-quality forage resources in the desert grasslands of Northwest my country. They are mainly distributed in Inner Mongolia, Shaanxi, Ningxia, Gansu and Xinjiang. Livestock plays an important role in developing and maintaining fragile ecosystems. [0003...
