Example Embodiment

[0011] Example one:

[0012] Pinus tabulaeformis: the amount of soaking liquid is 3.5%-4.5% of the seed mass, the liquid phase is 3-5% peach gum solution, the powder is raw ore powder, and the ratio of liquid to powder is (0.15-0.2):1. First add the liquid phase and rotate for 5-7s, add the powder after the seed surface is soaked, and then add the liquid phase and the powder at the same time, add in 10 times, after the addition, pelletize for 5-7s, rotate at 900-1000r, add powder for the last two times The speed is adjusted to 800r, and the last two curing times are 10s.

Example Embodiment

[0013] Embodiment two:

[0014] Sea buckthorn: the amount of soaking liquid is 3.5%-4.5% of the seed mass, the liquid phase is 3-5% peach gum solution, the raw ore powder is used as the powder, and the liquid-to-powder ratio is (0.15-0.2):1. First add the liquid phase and rotate for 5-7s, add the powder after the seeds are soaked, and then add the liquid and powder at the same time. The liquid and powder are added in 12 times. After the addition, the pelletizing is 5-7s, the rotation speed is 900-1000r, and the powder is added for the last two times. The liquid rotation speed is adjusted to 800r, and the last two curing times are 10-15s.

Example Embodiment

[0015] Embodiment three:

[0016] Ailanthus altissima: The amount of soaking liquid is 4.0%-5.0% of the seed mass, the liquid phase is 3-5% peach gum solution, and the raw ore powder is used as the powder. The ratio of liquid to powder is (0.15-0.2):1. First add the liquid phase and rotate for 7-10s, add the powder after the seeds are soaked, and then add the liquid and powder at the same time. The liquid and powder are added in 8 times. After the addition, the pelletizing is 5-7s, the rotation speed is 800-900r, and the last two times are added. The liquid rotation speed is adjusted to 800r, and the last two curing times are 10-15s.

Abstract

The invention relates to the field of forest tree seed culturing, in particular to a method for preparing forest tree seed pelleting coatings. An adhesive directly serves as liquid, and the amount and the concentration of the added liquid, the liquid-powder ratio, the liquid-powder adding interval, the amount of the liquid added during last-time curing and curing time are controlled. The method has the advantages that in a traditional method, an adhesive is only added once and is added in the beginning, and liquid added in several times of following pelleting is water; in the method, the adhesive serves as the liquid and is used all the time in the whole process; compared with the traditional coating method, the liquid with the adhesive (a peach gum and sodium carboxymethylcellulose solution) and powder are added at the same time, and the liquid-powder ratio, the concentration of the liquid, the once adding amount, the interval, the rotating speed of a pelleting coating device and the like are strictly controlled; by means of the preparing method, the pelleting coatings can be smooth in surface, even in coloring and not prone to breakage.

Description

technical field [0001] The invention relates to the technical field of forest tree seed cultivation, in particular to a method for preparing pelletized coating of forest tree seeds. Background technique [0002] Seed coating is divided into pelletization and film coating. Seed pelleting is mainly used to increase seed weight, add growth regulators, pesticides, repellents, water retaining agents, etc. to promote seed growth. In some advanced countries in the world, the planting crops, vegetables, flowers, forestry seedlings and aerial afforestation are all coated with seeds. Especially in some American and European countries, the coating of aerial seeds has become the key to improve the effect of afforestation. technology. [0003] The coating accuracy of foreign equipment is high, but the cost is too high. One piece of equipment costs three to four million yuan, and it is too wasteful for aerial sowing of forestry seeds. Simple domestic equipment can cost three to four mil...
