Pneumatic pollination control device for large row ratio hybrid rice seed production

Abstract

The invention discloses a pneumatic pollination control device for large row ratio hybrid rice seed production. The pneumatic pollination control device comprises a base, wherein rolling wheels are installed at the bottom of the base, and the base is connected with a push handle; a lifting device is installed on the base and an air pump is installed on the lifting device; an L-shaped pollination tube is connected to the air outlet end of the air pump, and strip-shaped air nozzles are formed in two sides of the L-shaped pollination tube; L-shaped pollen collection tubes are installed above andbelow the L-shaped pollination tube, and strip-shaped trumpet-shaped pollen collection ports are formed in two sides of the L-shaped pollen collection tube; filter screens are installed at the pollencollection ports; the L-shaped pollen collection tubes communicate with an air inlet of the air pump; and the air pump and a stepping motor are in wireless or wired connection with a wind speed and direction sensor. Pollen which is not adhered to rice can be recovered and ejected again, so that the pollination rate of rice is increased, intensity of ejected airflow can be adjusted according to thewind direction and the wind force, and most of the pollen can fall to a preset falling place.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a pneumatic pollination control device for large row ratio hybrid rice seed production. Background technique [0002] Pollination is one of the important steps in the production process of hybrid rice. At present, in order to increase the artificial pollination efficiency of hybrid rice, a kind of pneumatic pollination device has been invented. But the existing pneumatic pollination device has the following problems: 1. the existing gas pollination device only blows off the stamen powder, but in fact most of the pollen will not fall on the pistil, so that the pollen has only one chance of pollination, resulting in Insufficient pollination. 2. There will be natural wind outside, and the wind direction and wind force are uncertain, so the pollen may not fall to the preset area for pollination when blowing. Contents of the invention [0003] The invention discloses a large-row-ratio hy...

But the existing pneumatic pollination device has the following problems: 1. the existing gas pollination device only blows off the stamen powder, but in fact most of the pollen will not fall on the pistil, so that the pollen has only one chance of pollination, resulting in poor pollination

2. There will be natural wind outside, and the wind direction and wind force are uncertain, so the pollen may not fall to the preset area for pollination when blowing air
