Corn seed production pollinating machine

Abstract

The invention discloses a corn seed production pollinating machine. The corn seed production pollinating machine comprises a pollinating gun body, wherein a handle is fixedly arranged at one end of the lower side of the pollinating gun body; an air pressing cavity is arranged in one end of the pollinating gun body; a rubber piston is arranged in the air pressing cavity; a piston rod is mounted at one end of the middle of the rubber piston; the piston rod penetrates through an air pressing hole and a push-pull handle is fixedly mounted at one end of the piston rod; the pollinating gun head is arranged at one end of the pollinating gun body; a pollinating pipe is connected with one end of the air pressing cavity; the pollinating pipe penetrates through one end of the pollinating gun head; the upper side of the pollinating gun body is in thread connection with a dust collection funnel; the upper end of the dust collection funnel is connected with a funnel cover through a hinge; a powder discharging valve is arranged at the lower side of the dust collection funnel; the lower end of the dust collection funnel is communicated with the pollinating pipe; the lower side of the air pressing cavity is connected with an air pump pipe. According to the corn seed production pollinating machine, corn pollen is sprayed through air pressure; the corn seed production pollinating machine has a relatively good pollinating effect, and is simple to operate and convenient to use, and the efficiency of artificial pollination is improved.

Description

technical field [0001] The invention relates to the technical field of corn pollination, in particular to a pollinator for corn seed production. Background technique [0002] The pollination method of corn flowers belongs to cross-pollination. Corn is a unisexual flower. The male flowers are born on the top of the plant, and the female flowers are born in the leaf axils. Cornflowers are anemophilous flowers, relying on the wind to spread their pollen. When maize encounters unfavorable climatic conditions such as drought, high temperature, and continuous rain during the flowering period, there will often be uncoordinated male and female flowering periods, excessively long ear bracts, difficulty in drawing silk, less pollen, and weak pollen vitality, which will affect normal pollination. Fertilization and set, resulting in poor set, resulting in severe baldness. If it is found that the pollination rate of male flowers in the field is lower than 40%, artificial assisted polli...

Problems solved by technology

[0003] The existing artificial pollination technology in the flowering stage of corn mostly uses paper bags to collect pollen, and then shakes the pollen on the paper bag to the stamen stigma. less effective
