Abstract

The invention provides an artificial supplementary pollination tool for corns, which relates to the technical field of corn breeding and is used for solving the problems that pollens carry anthers or other impurities so that the pollens are impure and further the efficiency is low in an existing corn pollen collection and pollination manner. The artificial supplementary pollination tool comprises a bottle bottom, a first bottle body, a second bottle body and a third bottle body which are detachably connected in sequence; a bottle opening is formed in a free end of the third bottle body and a bottle cap is arranged on the bottle opening; a second mesh screen is arranged at one end, which is connected with the second bottle body, of the first bottle body, and is provided with a second through hole through which only the pure corn pollens can pass; and a first mesh screen is arranged in the bottle opening and a first through hole through which the pollens with the average diameters of 40-50 microns can pass is formed in the first mesh screen. The tool can be used for screening the collected pollens to obtain the pure corn pollens. Meanwhile, the bottle bodies are pressed to spray out the pollens and the operation is convenient and simple; and the bottle bodies can be immediately recovered after being released from the hand, so that the supplementary pollination can be carried out again and the pollination efficiency is high.

Description

technical field [0001] The invention relates to the technical field of corn breeding, in particular to an artificial assisted pollination device for corn. 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 ...
