Corn cross pollination device

Abstract

The invention relates to a corn cross pollination device. A shell is internally provided with a box body used for containing pollen, the box body is fixed to the shell, a rotary shaft penetrates through the interior of the box body, and is in motive seal with the contact face of the box body, one end of the rotary shaft penetrates through the box body and the shell and then is connected with an output shaft of a motor, and the motor is fixed to the shell; the other end of the rotary shaft penetrates out of the box body and the shell, then the tail end of the rotary shaft is fixedly connected with a first mounting block, the side, away from the rotary shaft, of the first mounting block is provided with a blade part used for pruning bracts of corn female ears to conveniently expose filaments, and the middle of the first mounting block is provided with a first through hole serving as a pollen channel; the tail end of the first through hole is provided with a butterfly valve for controlling outflow of the pollen, the top of the first through hole is communicated with a blind hole formed inside the rotary shaft, the blind hole is coaxial with the rotary shaft, and the outer wall of thepart, located in the box body, of the rotary shaft is provided with multiple second through holes communicated with the blind hole. The corn cross pollination device is easy to operate, the labor intensity of hand pollination can be lowered, and the cross pollination efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of corn breeding, in particular to a corn hybrid pollinator. Background technique [0002] When carrying out maize breeding, in order to increase the yield, breeders must carry out the propagation of hybrid lines. In the actual breeding process, the failure of flowering due to drought or other reasons is a problem that is often encountered, that is, the tassel powder of maize has already It was over, but the ears hadn't spun silk because the bracts were too long or the bracts were tightly wrapped, which brought a lot of trouble for pollination. Existing research results have shown that all parts of the filaments have the ability to receive pollen and be fertilized. Therefore, the common operation method for failure in the flowering period is to manually cut off the bract leaves horizontally to expose the filaments inside, and then artificially pollinate the filaments. The labor intensity of the operation is...

[0002] When carrying out maize breeding, in order to increase the yield, breeders must carry out the propagation of hybrid lines. In the actual breeding process, the failure of flowering due to drought or other reasons is a problem that is often encountered, that is, the tassel powder of maize has already It is over, but the ears have not spun silk because the bracts are too long or the bracts are tightly wrapped, which brings a lot of trouble for pollination

Existing research results have shown that all parts of the filaments have the ability to receive pollen and be fertilized. Therefore, the common operation method for failure in the flowering period is to manually cut off the bract leaves horizontally to expose the filaments inside, and then artificially pollinate the filaments. The labor intensity of the operation is high, and the time and economic cost are large. At present, there is no device specially using this technology for cross-pollination
