Description

Technical Field

[0001] This utility model relates to the field of sunflower emasculation technology, specifically a tool for quickly removing male flowers from sunflowers. Background Technology

[0002] The process of quickly removing the male flowers of a sunflower is also known as emasculation. In crop hybridization breeding and the utilization of heterosis, emasculation is a method of removing the stamens from the sunflower body in order to produce hybrid varieties. When performing artificial emasculation, it is necessary to understand the floral structure and flowering habits of various crops and to emasculate at the appropriate time to improve the success rate of hybridization.

[0003] Existing tools for quickly removing male sunflower flowers are mostly optimized to reduce severe damage to the thumb, offering flexible and convenient operation and significantly saving work time. For example, Chinese utility model patent application number CN201520563116.6 discloses a "Portable Demasking Device." This device is characterized by a collar that can be fitted onto the thumb, with a forward-extending cutting blade on the collar. The forward extension of the cutting blade slightly exceeds the forward extension length of the thumb. This reasonable structure minimizes damage to the ovary wall during operation and ensures thorough emasculation, solving the problem of severe thumb damage in this task. Its flexible and convenient operation greatly saves work time and has the advantages of simple structure, easy worker operation, and economic practicality.

[0004] While the aforementioned tools for quickly removing sunflower male flowers have advantages in reducing serious damage to the thumb, being flexible and easy to operate, and greatly saving work time, they still have certain drawbacks: during the process of removing the male flower stamens, pollen will scatter due to the pulling force applied by the personnel, which can easily lead to self-pollination, and the pollen will fall randomly on the ground, requiring personnel to clean it up.
