Blowing pollinator and method for using same to carry out blowing pollination

Abstract

The invention relates to the field of cross breeding, in particular to a blowing pollinator and a method for using the same to carry out blowing pollination. The blowing pollinator comprises a fan and an air guide; the air outlet of the fan is connected with the air guide, and the air outlet end of the air guide is connected with two air nozzles; each air nozzle is an adjustable air nozzle, and can adjust the angle between the jetted airflow and the horizontal plane; each air nozzle is perpendicular to the air outlet end of the air guide, i.e., the flowing direction is changed by 90 degrees after the airflow enters the air nozzle via the air guide; the two air nozzles respectively face up at the left and the right of the air outlet end of the air guide; and the fan is connected with a storage battery for supplying power and a flow velocity regulator for regulating the velocity of the airflow. The blowing pollinator and the blowing pollination method provided by the invention can utilize the airflow to directly blow the mature pollen of male parents into the air over a male parent area, the pollen then spontaneously falls to finish the pollination process, and thereby the setting rate of the cross breeding can be remarkably increased.

Description

Technical field [0001] The invention relates to the field of hybrid breeding, in particular to a blowing pollinator and a method for blowing pollination using the blowing pollinator. Background technique [0002] With the development of human society, population pressure and people's material and cultural needs have made traditional crops unable to meet the actual needs in terms of yield and quality. Therefore, there is an urgent need to improve crops. Cross breeding is now widely used as an improvement method. In the process of cross breeding, pollination is one of the most important and difficult to control links. Traditionally, the male parent's flower ears are directly blown by natural wind to pollinate the female parent's area. The seed setting rate of hybrid breeding is small, the yield is the lowest and uncontrollable, and it is far from reaching the breeding requirements; now hybrid breeding such as rice and corn are generally passed Pollination is done by manually using...

Problems solved by technology

Traditionally, the flower spikes of the male parent are blown directly by natural wind to pollinate the female parent. Manually beat the panicle neck of the plant with a bamboo pole or use machine parts to directly vibrate the plant panicle neck to pollinate, separate the pollen of the male parent from the flower spike and fly it to the female parent area for flower spike pollination, or blow the male parent directly by natural wind Flower spikes pollinate the female parent area, and the flying distance of pollen is too short in either way, resulting in low seed setting rate
