Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for corn seed production, and more specifically, to a spraying device for corn seed production. Background Technology

[0002] The main purpose of maize seed production is to produce high-quality and high-yield maize varieties. Furthermore, by controlling hybridization, two or more parents with different beneficial genetic characteristics can be crossed together to further improve the quality of the next generation of maize seeds, increase disease resistance, and obtain higher yields.

[0003] When processing corn seeds, it is necessary to spray the seeds to reduce the occurrence of diseases. However, common spraying methods are not convenient for adjusting the spraying height according to the thickness of the corn seeds, which affects the efficacy of the pesticides. Therefore, we have proposed a spraying device for corn seed production to solve the above-mentioned problems. Utility Model Content
