Abstract: 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/hm² and 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.
