通过大田结合室内分析的方法,研究了不同氮磷配施方式下胡麻干物质的积累规律和产量形成.结果表明：单施低氮75 kg/hm2和单施中磷150 kg/hm2时胡麻植株的干物质积累最大,日均增加量分别达44.11 mg/d,46.16 mg/d,较不施肥分别提高22.84%和28.70%.配施氮磷均为150 kg/hm2胡麻植株干物质积累及最终积累量最大,日均增加量达49.30 mg/d,单株干物质积累量达4.95 g,分别较不施肥提高了37.44%,37.03%.根、茎、叶、非籽粒、籽粒干物质的最终积累量和分配比率最大的处理分别为单施低磷(75 kg/hm2)、施中氮(150 kg/hm2)和高磷225 kg/hm2、施中氮和低磷、单施中磷、施氮磷均为150 kg/hm2,且单施低氮叶物质对籽粒的转移率和贡献率最大,较不施肥均有显著提高.施低氮和中磷胡麻的产量最大,达2200.00 kg/hm2,较不施肥提高36.43%.可见,150 kg/hm2氮和150~225 kg/hm2磷配施时胡麻的干物质积累量、籽粒干物质最终积累量和分配比率、产量均达最大.

Dry matters accumulation law and yield formation of oil flax in irrigated field in various ni-trogen and phosphorus fertilization were studied by connecting field with lab analysis.The result showed that low nitrogen(75 kg/hm2 )fertilization and phosphorus middle fertilization (150 kg/hm2 )improved maximum the dry matters accumulation,which increased of 44.11 mg/d and 46.16 mg/d,and 22.84% and 28.70% higher than no fertilization.Fertilization at 150 kg/hm2 with nitrogen and phosphorus accumulated the maximum the dry matters,and the daily increasing was 49.30 mg/d,each plant get 4.95 g,which was 37.44% and 37.03% higher than no fertilization.The final and maximum accumulation and distribution in root,stem,leaves and grain were found at low phosphorus (75 kg/hm2 ),high nitrogen (150 kg/hm2 )and high phosphorus (225 kg/hm2 ),high nitrogen and low phosphorus,middle phosphorus,nitrogen and phos-phorus at 150 kg/hm2 .Low nitrogen contributed the leaf material for grain transfer rate and contribution rate was the maximum.All treatments were significantly higher than no fertilization.High nitrogen and phosphorus at 150~225 kg/hm2 was better for the formation of output.Low nitrogen and middle phos-phorus get the maximum the output,reached 2 200.00 kg/hm2 ,was 36.43% higher than no fertilization.It is suggested that nitrogen at 150 kg/hm2 and phosphorus at 150~225 kg/hm2 increase dry matter accumu-lation in oil flax,the final dry matter accumulation and distribution of the grain and output formation could be the maximum.
