A portable pollination device applied to corn seed production

Abstract

The invention discloses a portable pollination device applied to maize seed production, and relates to the technical field of maize breeding. The portable pollination device comprises a pollen collection unit and a pollination unit; the pollen collection unit comprises a pollen collection body, the pollen collection body comprises a pollen collection hopper, a first sieve plate is arranged inside the pollen collection hopper, a second handle is arranged on a side surface of the pollen collection hopper, the second handle is hinged with the middle part of a first hand, and the upper part of the first handle is hinged with the middle part of a connecting rod; a fixing plate is arranged at the big end of the pollen collection hopper, two sides of the fixing plate are hinged with a first baffle plate and a second baffle plate respectively, and the first baffle plate and the second baffle plate are connected with two ends of the connecting rod through hinge assemblies; the pollination unit comprises a pollination hopper, a second sieve plate and a moving sieve plate glidingly connected with the pollination hopper. During pollen collection, the device can receive pollen falling off from tassels without blind areas, the pollination unit can be used as a pollen storage device as well as a pollination device, and the process including pollen collection, pollen sieving and pollination can be completely once.

Description

technical field [0001] The invention relates to the technical field of corn breeding, in particular to a portable pollination device applied to corn seed production. Background technique [0002] Doing a good job in artificial assisted pollination is an effective means to increase the seed setting rate and increase the yield of seed production. Generally, it should be carried out continuously for 2 to 3 times during the blooming period. Practice has proved that the general combined farming system can increase the yield by 50-100 jin per mu through artificial assisted pollination, and the combination of high female parent and low male parent and the combination of difficult natural pollination can increase the yield by 200-300 jin. [0003] The method currently used is generally the pollination method, that is, during the pollination period, especially in the morning of the first flowering period, the pollen on the tassels of the male parent is collected, the anthers are remo...

Problems solved by technology

[0004] 1. High labor intensity and low work efficiency

[0005] 2. It is difficult to collect pollen. The traditional method of collecting pollen requires one hand to hold the tassel and shake it gently, and the other hand to catch the pollen with a pollinator. However, since the tassel of corn grows on the top of the corn, the pollen collection In order to make the pollen fall into the pollen collector smoothly, the top of the corn must be bent. In this process, if the curvature is too large, the growth of the corn will be affected, and if the curvature is too small, some pollen will not be able to fall into the powder collector, causing waste

On the other hand, since the tassels of corn grow on the top of the corn, the arms are always raised during the process of picking flour, which is very labor-intensive.

[0006] 3. The traditional pollination method requires multiple transfers of pollen during the pollination process, which is easy to cause pollution
