Pneumatic pollination device and method for large row ratio hybrid rice seed production

Abstract

The invention discloses a large row ratio hybrid rice seed production pneumatic pollination device and a method thereof. The device comprises a pneumatic pollination component, a controller, a lifting adjustment component, and a four-wheel power chassis; the pneumatic pollination component is installed on the front part of the four-wheel power chassis 1 through the lifting adjustment component, and the controller is installed on the top of the four-wheel power chassis . In the present invention, the airflow of each pollination tube acts on the panicle of the male parent row of hybrid rice respectively, so that the pollen of the male parent separates from the stamen and drifts to the female parent box. The airflow speed of the pollination tubes of each male parent row is different to ensure that the pollen is transported to the main female In this area of ​​action, the directional drift of pollen and uniform pollination are realized, and a working device is provided for the mechanized and efficient pollination of hybrid rice seed production.

Description

technical field [0001] The invention relates to a field mechanized pollination device for hybrid rice seed production, in particular to a pneumatic pollination device and method suitable for large-scale seed production and planting with a large row ratio of parents. Background technique [0002] Hybrid rice seeds are the material basis for hybrid rice production, but rice is a self-pollinated plant, and the natural hybridization rate in the natural environment is generally only 0.2% to 0.3%. To maintain the hybrid advantage of the seeds, at present, only by means of "manual operation" "Pollination to ensure sufficient and uniform pollination, increase the rate of outcrossing seed setting, and improve the yield and quality of seed production. The flowering period of rice pollen is only 7-10 days, and the flowering time is only about 2-4 hours a day, so pollination must be completed within a limited time. [0003] At present, there is no applicable pollination machinery and e...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem of lack of mechanized pollination equipment in the current hybrid rice seed production, meet the needs of large-scale large-scale seed production, and provide a large-row ratio hybrid rice seed production pneumatic pollination device, through which each pollinator acts on different females. In this area, to achieve directional, uniform and efficient pollination
