摘　　要：为进一步丰富南方冬季亚麻纤维与种子兼收的栽培理论与技术和促进南方冬季油纤兼用亚麻产业提供理论与生产实践指导。研究亚麻播种期、耕作方式和施肥水平等关键措施对亚麻原茎和种子产量的影响,探讨了洞庭湖区亚麻原茎与种子兼收的抗倒伏高产栽培技术。结果表明：早播免耕不施肥处理抗倒伏效果最好,较轻级（0-4级）倒伏率总和为18.33%,最高级（5级）倒伏率为零,原茎产量和种子产量为最高,依次分别达到8375.77 kg/hm2和804.46 kg/hm2,同时,试验总结出了亚麻抗倒伏、高产、高效栽培关键技术,为洞庭湖地区油纤兼用亚麻大面积种植提供了技术保证。The aims were to further enrich the cultivation theory on the south flax fiber and seeds＇ destinations in winter and promote the practical guidance on the south oil flax combination with fiber industry in areas of theory and production in winter. It would study the impact on flax stem and seed production made by the key measures such as flax seeding time, tillage method and fertilization level in this paper. It also explored the lodging resistance and high yield cultivation techniques of flax stem and seeds＇ combination in Dongting Lake area. The results showed that it was the best way to develop the lodging resistance by early sowing no-till no fertilizing, lighter level（0 to 4） the sum rate of lodging was 18.33%,the highest level（5） the rate of lodging was zero, stem yield and seed yield highest, followed in turn 8375.77 kg/hm2and 804.46 kg/hm2. At the same time,The test also summed up the key technology of flax lodging resistance, high-yield and efficient cultivation which could provide technical assurance of oil flax fiber combined large scale cultivated in Dongting Lake area.
