Abstract

The invention discloses an air-sweeping type hybrid rice seed production pollination machine and an operation method thereof. The air-sweeping type hybrid rice seed production pollination machine comprises a power chassis mechanism, a truss, a plurality of position-adjustable ducted fan type pollinator mechanisms and a lifting mechanism, wherein the ducted fan type pollinator mechanisms are arranged on the truss, and the lifting mechanism is connected with the power chassis mechanism and used for adjusting the height of the truss. Each ducted fan type pollinator mechanism comprises a support,two airflow ducts, rotor wings, a motor and a protecting net, wherein the two airflow ducts are arranged on the support, the rotor wings in opposite rotation directions are arranged in the two airflowducts, the motor drives the rotor wings to rotate, and the protecting net is used for protecting the rotor wings. The air-sweeping type hybrid rice seed production pollination machine is high in pollination operation efficiency, more uniform in pollination, high in controllability, low in labor intensity and suitable for auxiliary pollination of different varieties of hybrid rice, and the operation method conforms to large-scale operation.

Description

Technical field [0001] The invention relates to the field of hybrid breeding, in particular to an air-blowing type hybrid rice seed production pollinator and an operation method thereof. Background technique [0002] Hybrid rice seed production is an important part of hybrid rice production, and pollination is a key link in hybrid rice seed production; sufficient and uniform pollination is the prerequisite guarantee for improving the quality and yield of seed production; currently, the auxiliary pollination method for hybrid rice seed production is mainly Mainly based on traditional manpower. For hybrid rice seeding, at least 3 pollen is required on each pistil style, so that the seed produced can maintain the excellent characteristics of the parents and grow into high-quality, high-yielding hybrid rice seeds. [0003] Traditional natural pollination is to directly use natural wind to blow up the male parent's flower ears to pollinate the female parent area. The hybridization rate...
