摘要： 为促进南方冬季油纤兼用亚麻产业，采用氮、磷、钾不同配比的施肥方式共设置了14个施肥处理，通过对2个品种在不同试验点进行不同施肥处理比较试验，以便筛选出最适合洞庭湖区当地亚麻种植的施肥方案。结果表明：在低洼试点与旱地试点中通过合理的施肥调控油纤兼用亚麻可获得高产，表现最好的亚麻品种是‘轮选2号’。在低洼试点中，原茎产量最高达7000.30 kg/hm2，种子产量高达538.90 kg/hm2；在旱地试点中，原茎产量达5520.30 kg/hm2，种子产量达424.96 kg/hm2。在施肥技术方面，针对于低洼稻田种植‘中亚麻2号’的最佳施肥为N2P0K2 N 400 kg/hm2、P2O5 15 kg/hm2、K2O 125 kg/hm2)；‘轮选2号’的最佳施肥为N2P2K0 N 350 kg/hm2、P2O5 25 kg/hm2、K2O不施用。而针对于旱地地区中，‘中亚麻2号’以N2P2K0 (N 375 kg/hm2、P2O5 52.5 kg/hm2、K2O不施用最好；‘轮选2号’以N2P0K2 (N 400 kg/hm2、P2O5 10 kg/hm2、K2O 150 kg/hm2)最好。

Abstract: In order to promote the industry of fiber combination oil flax in winter in south China, 14 fertilizer treatments were set by using different fertilizer application ratios of nitrogen, phosphorus and potassium, two cultivars were tested under different fertilization treatments in different test points, so as to select the best implementation plan which could fit the growth of flax in Dongting Lake. Fiber combination oil flax obtained high-yield through reasonable fertilization regulation in low-lying and dry land pilot, the best performance was cultivar ‘Lunxuan-2’. In low-lying pilot, the stem yield was 7000.30 kg/hm2, the seed yield was 538.90 kg/hm2. In dry land pilot, the stem yield was 5520.30 kg/hm2, and the seed yield was 424.96 kg/hm2. For fertilization techniques, the optimal fertilization for ‘Zhongya No.2’ in the low-lying paddy field was N2P0K2 (N 400 kg/hm2, P2O5 15 kg/hm2, K2O 125 kg/hm2), and for ‘Lunxuan-2’ was N2P2K0 (N 350 kg/hm2, P2O5 25 kg/hm2, K2O 0). In dry land pilot, the optimal fertilization for ‘Zhongya No.2’ was N2P2K0 (N 375 kg/hm2, P2O5 52.5 kg/hm2, K2O 0), and for ‘Lunxuan-2’ was N2P0K2 (N 400 kg/hm2, P2O5 10 kg/hm2, K2O 150 kg/hm2).
