Pipeline air supply type hybrid rice seed production pollinator and operation method thereof

Abstract

The invention discloses a pipeline air supply type hybrid rice seed production pollinator and an operation method thereof. The pipeline air supply type hybrid rice seed production pollinator comprisesa power chassis mechanism, a truss, a plurality of pipeline air supply type pollinators, and a lifting mechanism, wherein the power chassis mechanism is used for providing power; a plurality of the pipeline air supply type pollinators are arranged on the truss and are adjustable in position; the lifting mechanism is connected with the power chassis mechanism for adjusting the height of the truss;and the pipeline air supply type pollinator mechanism comprises an air flow conveying pipe, a fixing bracket for mounting the air flow conveying pipe on the truss, a plurality of pipeline air supplytype pollinators communicated with the air flow conveying pipe, a fan for providing an air source, and an air flow distributor for adjusting and distributing air flow. The pipeline air supply type hybrid rice seed production pollinator can avoid the phenomenon of missing regional pollination, has high pollination operation efficiency, uniform pollination and high controllability, is suitable for large-scale operation, has low labor intensity, and can be suitable for auxiliary pollination of hybrid rice of different varieties.

Description

technical field [0001] The invention relates to the field of hybrid breeding, in particular to a ducted air-supply type hybrid rice seed production pollinator and an operating 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 for improving seed production quality and yield; currently, the auxiliary pollination methods for hybrid rice seed production are mainly Mainly traditional manpower. For hybrid rice to bear fruit, at least 3 grains of pollen are required on each pistil style, so that the seeds that bear fruit can maintain the excellent traits of the parents and grow into high-quality, high-yield hybrid rice seeds. [0003] The traditional natural pollination is to directly blow the male flower spikes to pollinate the female parent area through natural wind. The hybridization rate is ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at overcoming at least one deficiency of the above-mentioned prior art, and provides a pipeline air-supply type hybrid rice seed production pollinator. When the response speed of the truss leveling device is too large, it can still ensure that the airflow of the pollinator does not leave the rice panicle layer, avoiding the phenomenon of lack of regional pollination, and the pollination operation efficiency is high, the pollination is more uniform, and the controllability is high.
