Sorghum hybridization castration auxiliary device

Abstract

The invention relates to the field of plant breeding appliances, and particularly discloses a sorghum hybridization castration auxiliary device which comprises a shell, a shading tent, a positioning pile, an air inlet unit, a fixing unit and an amplifying device, the shell is in a vertical cylindrical shape, the upper end of the shell is sealed and connected with the shading tent, the lower end of the shell is connected with universal wheels, and the positioning pile is slidably connected into the shell; the positioning pile is in a nail shape with a thick upper part and a thin lower part, the lower end of the positioning pile is connected with a pedal, the positioning pile can be nailed into soil by treading the pedal, a spring is connected between the upper end of the positioning pile and the top of the shell, and the positioning pile separated from the soil can move upwards along the inner wall of the shell through the spring. By means of vertical displacement of the positioning pile, the whole auxiliary device is fixed, meanwhile, sorghum stems can be fixed together through inflation of the air bag, in the whole operation process, stability of the device and plants is guaranteed, one hand of an operator is liberated, and the operator can conduct more refined operation with the two hands.

Description

technical field [0001] The invention relates to the field of plant breeding equipment, in particular to an auxiliary device for emasculation of sorghum hybridization. Background technique [0002] In the artificial hybridization of sorghum, a series of operations such as ear selection, tasseling and bagging, and pollination are required. During the operation, workers need to hold the sorghum stalk with one hand, and use scissors to remove the infertile stalks first. Stemless spikelets are trimmed off, and then the remaining stalked spikelets are emasculated. When operating, hold the sorghum stem with one hand and open the glume of the sorghum ear with tweezers with the other hand. The tweezers need to avoid the ovary and stigma of the pistil, and then carefully pick out the three anthers of the stamen. The current problem of sorghum emasculation is: each sorghum contains a large number of spikelets, and each sorghum needs to handle 30 to 50 grains, which requires a lot of w...

AI Technical Summary

Problems solved by technology

The current problem of detasseling sorghum is that each sorghum contains a large number of spikelets, and each plant has to process 30 to 50 grains, which requires a lot of work and takes a long time. Depending on the ears and grains, it is very hard to work for a long time. Secondly, the emasculation of sorghum is mostly carried out in the afternoon. The environment is high temperature and high humidity, and the work intensity is high. Therefore, there is an urgent need for a tool to assist the staff in emasculation.
