2012~2015年采用单旋翼农用无人机分别在湖南、海南、广东杂交水稻制种基地对10个杂交组合父母本大行比制种,在不同自然风速条件下辅助授粉,通过田间花粉密度观测、母本异交结实率及制种产量考查研究授粉效果。结果表明,父母本行比6∶(40~60),单旋翼农用无人机辅助授粉的结实率和产量可达到甚至高于人工辅助授粉,说明单旋翼农用无人机可用于杂交水稻制种辅助授粉,促进制种全程机械化。
From 2012 to 2015, single-rotor agricultural UAV was used to pollinate parents and hybrids of 10 cross combinations in hybrid rice seed production bases of Hunan, Hainan and Guangdong respectively. Pollen density was assisted by field pollen density under different natural wind speed conditions. , Maternal outcrossing seed set rate and seed production test to study pollination effect. The results showed that compared with 6:40 (40-60), the seed setting rate and yield of agricultural single drone agricultural UAV assisted pollination can reach or even exceed the artificial pollination, indicating that single-rotor agricultural UAV can be used for hybrid rice seed production Assist pollination and promote full mechanization of seed production.
