Film-coating method for particle bird repellent

Abstract

The invention provides a film-coating method for a particle bird repellent. The film-coating method comprises the following steps: adding a carrier type particle bird repellent into a blender; spraying a water-soluble resin solution; continuously stirring for 20 to 60 minutes; then, drying for 40 to 80 minutes at the temperature of 20 to 40 DEG C; coating the surface of the carrier type particle bird repellent with resin after volatilization of a solvent to form a dry, smooth and dense film layer; spraying and wrapping with the water-soluble resin solution to obtain a resin-coated carrier typeparticle bird repellent. By adopting of the method, the bird repellent can be effectively protected, the medicinal effect is released slowly, and the bird repelling effect is improved and shelf lifeis prolonged.

Description

technical field [0001] The invention belongs to the technical field of bird repelling in agricultural planting, and in particular relates to a coating method of granular bird repelling agent. Background technique [0002] In recent years, with the continuous increase of national efforts to protect birds, the banning of highly toxic pesticides, the enhancement of farmers' awareness of bird protection and other factors superimposed, the ecological environment has been greatly improved, and the ensuing birds The number of species increases, and then the crops are more and more seriously harmed by birds. Bird damage is the most troublesome problem during the sowing and harvesting period. Bird damage during the sowing period can lead to lack of seedlings and broken ridges, and severe cases can cause almost no seedlings. During the harvest period, the birds pecked at the fruits again, resulting in a decline in crop quality and yield, and farmers suffered terribly. [0003] At pre...

Problems solved by technology

[0002] In recent years, with the continuous increase of national efforts to protect birds, the banning of highly toxic pesticides, the enhancement of farmers' awareness of bird protection and other factors superimposed, the ecological environment has been greatly improved, and the ensuing birds The number of species increases, and then the crops are more and more seriously harmed by birds. Bird damage is the most troublesome problem during the sowing and harvesting period. Bird damage during the sowing period can lead to lack of seedlings and broken ridges, and severe cases can cause almost no seedlings. During the harvest period, the birds pecked at the fruits again, resulting in a decline in crop quality and yield, and farmers suffered terribly

[0003] At present, traditional bird repelling methods mostly use sound or visual stimuli to drive birds, such as setting off firecrackers, beating gongs, scarecrows, horror eyes, bird repelling ribbons, etc. These methods are single, time-consuming and laborious, and birds can quickly apply them. Poor bird repelling effect

[0004] Most of the existing products use spraying or granule throwing, etc. These technical means are affected by bad weather factors, resulting in the decomposition and loss of active ingredients and failing to achieve the expected effect, that is, increasing the number of spraying and increasing the cost of pesticides. The economic burden also increases the risk of phytotoxicity. In an article with application number 201220391631.7, a convenient bird repellent drug pack has similar technical ideas to this technology. It needs to be processed into a small bag separately and attached to other particle repellent. bird repellant, but failed to combine this technology with bird repellent, which increases the cost and troubles to use
