| 摘要 | [Objectives] This study was conducted to improve the seed production efficiency of water-saving and drought-resistant hybrid millet in production. [Methods] A high-efficiency seed production technology for water-saving and drought-resistant hybrid millet varieties was developed by integrating aspects such as parental line sources, botanical characteristics, biological traits, seed production yield structure, key technical points of seed production, and suitable planting regions. [Results] Under standardized pre-sowing preparation and field management, both parents are simultaneously sown around May 20 with a planting row ratio of 2:6 (female:male), a row spacing of 20 cm and plant spacing of 10 cm for the female parent, and a row spacing of 35 cm and plant spacing of 15 cm for the male parent. Both parents are fertilized simultaneously with 375 kg/hm2 of urea at the booting stage combined with intertillage or rainfall, and 225 kg/hm2 of urea at the grain-filling stage combined with irrigation. Strict hybrid removal, proper pollination and timely harvesting can significantly increase the yield of seed production. [Conclusions] This technology can be fully applied to large-scale seed production of water-saving and drought-resistant hybrid millet, providing seed supply support for cultivation in arid and semi-arid regions. It helps alleviate issues such as excessive groundwater extraction and water scarcity while enhancing planting efficiency, increasing yield, and boosting increase of farmers' income. |
