Abstract

The invention discloses a pollinator for corn breeding, and belongs to the field of an artificial pollination device. The device comprises a shell, a driving block, a pollen spraying device, a power device and a coating device, wherein the shell is provided with a holding part; the driving block is rotatably arranged in the shell and comprises a pulling handle, a propelling part and a driving part; the driving part is of a tooth shape; the pollen spraying device comprises a propelling cylinder arranged in the shell, a piston arranged in the propelling cylinder, a first propelling rack meshed with the driving part, a pollination pipe of which one end runs through the inside of the propelling cylinder, an electromagnetic valve arranged on the pollination pipe, a travel switch and a processorfor controlling on-off of the electromagnetic valve; the power device comprises a second propelling rack, a reset spring and a propelling gear ring which are arranged in the shell in a slidable mode;the coating device comprises a pollination sleeve, a connection rod and a clamping hood. According to the invention, limited pollen is all centralized for pollination so as to avoid waste of the pollen; the pollinator is particularly suitable for small-batch experiment accurate pollination, high in pollination efficiency and convenient to operate.

Description

technical field [0001] The invention relates to the field of artificial pollination devices, in particular to a pollinator for corn breeding. Background technique [0002] Corn is one of the important food, feed and industrial raw material crops in China. In 2007, it became the largest food crop in my country. The social penetration rate of corn hybrids is extremely high, corn seed is the most commercialized food crop, and corn breeding is also the most commercialized. The traditional breeding mode in my country can be summed up as "small workshop" breeding, that is, the breeding innovation of the research group mode. Small scale, low efficiency, relying too much on empirical analysis. As for commercial breeding, the United States is the most advanced, emphasizing large-scale testing and identification. Through testing and mating a large number of new combinations, they are used in hybrid identification tests to screen out excellent combinations suitable for breeding goal...
