Problems solved by technology

However, the existing physical detasseling tools are mainly tweezers, which require the cooperation of both hands and personal experience, and take a long time, easily damage the pistil and stigma, and may even pull out the entire flower bud due to poor grasp of force

Embodiment Construction

[0005] The operation steps of the device in hybridization and detasseling are as follows: First, gently pinch the base of the flower bud with one hand, hold the main tube (9) with the other hand, insert the circumcision (12) into the flower bud, and then press the top of the device (1) with your fingers, and the spring in between (2) Contraction, the pressure shaft (3) slides downward under the restriction of the inner guide rail (4) and shaft edge (5), and presses the notch slope of the inner ring cutting cylinder (6) to make it rotate, and the ring cutting cylinder overcomes the inner spring (10) Resist and drive the circumcision knife (11) to remove the stamen group, corolla and sepals of the flower bud. Finally, when the export port on the main tube overlaps with the export port of the circumcision cylinder, gently shake out the sepals, petals and stamen groups cut off by the circumcision knife, and the step ends at this point.

Abstract

The invention relates to a hybrid emasculation device for buds, and in particular relates to a hybrid emasculation tool for buds, comprising an emasculation tool body and an emasculation knife, wherein the power of the emasculation tool body is from human finger pressing, and the emasculation tool body is internally provided with a pressure shaft, sliding rails, a bevel notch, a return spring and the emasculation knife. By inserting buds into the bottom opening of the tool and pressing the top end of the tool, the sepals, petals and stamens on the buds can be removed entirely, and thus the pistil of the buds is naked, so that the entire hybridization operation is more convenient and time-saving.

Description

technical field [0001] The invention relates to the technical field of hybrid breeding, specifically the physical castration technology of sexual hybrid breeding. Background technique [0002] Sexual hybridization is currently the main way of soybean breeding, and hybridization technology is the key to the success of sexual hybridization [1]. However, the existing physical detasseling tools are mainly tweezers, which require the cooperation of both hands and personal experience, and take a long time, easily damage the pistil and stigma, and may even pull out the entire flower bud due to poor grasp of force. In addition, other hybrid seed production also involves the step of emasculation, such as tomato hybrid seed production [2], in sexual hybrid crops, emasculation is the only way, and the effect of emasculation will inevitably affect the hybridization results. There is no shortage of innovations in the detasseling tool for small flower buds. The patent "A Soybean Pollinat...
