摘要
从父母本种植比例、施肥水平、单株授粉花数、授粉时间、制种季别等方面在湖南对烤烟杂种制种技术进行了研究。结果表明,父母本种植比例以1:3较好;单株授粉花数以40-60朵为宜;在南方中等肥力田块制种以施纯氮195-210kg/hm2较理想;较适宜的授粉时间为10:00和16:00左右。利用前季收获后的再生杈烟进行杂交种后季制种,在提高杂交种子产量,降低劳动力投入和生产成本等方面具有较理想的效果。
An experiment was carried out based on the ratio of male parent to female parent, the fertilization level, the number of pollinated flower per plant, pollination time during daytime and seed production in different crop season to study seed production techniques of flue-cured tobacco MS hybrid in Hunan Province. The results showed that the optimum ratio of male parent to female parent was： 1：3, and 210 kg/hm2 N fertilization was better. The results showed that plant with 40-60 pollinated flowers produced higher yield and quality seeds, and the optimum pollination time was 10：00-11：00 AM and 4：00-5：00 PM. It was concluded that hybrid seed production in two crop seasons, especially the second crop season based on the utilization of ratoon was beneficial to higher seed yield with lower production and labor cost.
