Description

Technical Field

[0001] The present invention relates to the technical field of hybrid rice seed production, and specifically to a hormone spraying device for hybrid rice seed production fields. Background Art

[0002] Hybrid rice seed production fields refer to fields specifically used for producing hybrid rice seeds. In these fields, through scientific methods and strict management measures, specific parental materials (i.e., male parent and female parent) are planted to produce high-quality hybrid rice seeds. Exogenous hormones such as gibberellin (GA3), indole acetic acid (IAA), etc. need to be sprayed during the hybrid rice seed production process, which can be used to promote the growth and development of plants, increase the seed setting rate, and improve the quality of seeds. Currently, generally, a backpack spraying structure or a spray bottle is used for spraying, and the exogenous hormones are generally solid. Before spraying, a solvent needs to be added to make them into a liquid state, and then poured into the backpack spraying structure or the spray bottle for spraying.

[0003] However, the backpack spraying structure or the spray bottle cannot achieve quantitative spraying. Operators can only rely on personal experience to judge the amount of hormone sprayed, which easily leads to over-spraying or under-spraying, resulting in drug waste, and the spraying is uneven, causing uneven growth of rice and reducing the seed production efficiency; in addition, there is a long time interval between the preparation and the final spraying. Especially when the concentration is relatively dilute, if the prepared exogenous hormone is left standing for a long time, at a relatively high environmental temperature in summer, it is very easy to cause its deterioration and weakening or even loss of biological activity.

Release the piston rod, and the resilience of the spring drives the driving rod and the piston rod to move upward to draw the hormone solution in the working chamber into the syringe barrel. Then press the driving rod again to spray the hormone solution onto the rice through the spray head. In this way, the hormone solution can be quantitatively injected, avoiding overspraying or underspraying, saving costs, and increasing the seed production efficiency. In addition, by arranging the spring, the driving rod, and the guide cylinder, and using the resilience of the spring to suck the hormone solution into the syringe barrel, the operator only needs to press and spray, saving labor costs.
