为了明确氮磷对胡麻茎叶中生理指标及产量构成因子的影响，以陇亚杂1号为材料，设计不施肥、施磷、施氮和氮磷配施4个处理。在大田条件下，研究了灌溉地陇亚杂1号整个生育期茎、叶中叶绿素a、叶绿素b、总叶绿素、可溶性糖的动态变化。结果表明，叶绿素a和总叶绿素含量动态变化一致，呈先升后降趋势；叶片中叶绿素a和总叶绿素含量高峰值出现在现蕾期，茎中出现在盛花期；叶中可溶性糖含量先降后升，茎中呈降-升-降趋势；可溶性糖累积量，茎中先升后降，呈倒V型，最高值出现在绿熟期，叶中可溶性糖累积量也呈倒V型，最高值出现在盛花期。胡麻茎叶中叶绿素a、总叶绿素、可溶性糖含量和累积量都随氮磷增加而增加；氮磷配施与不施肥（CK）相比胡麻产量构成因子中单株蒴果数、每果籽粒数、千粒重及产量，分别提高了27．97％、16．13％、18．52％和49．07％。

To understand the effects of nitrogen (N)and phosphorus (P)on physiological characteristics and yield of oil flax,the cultivar Longyaza 1 was studied in fields under no-fertilizer (CK),P-fertilizer,N-fertiliz-er and NP-fertilizer.Dynamical changes of chlorophyll content and soluble sugar in leaf and stem during develop-ment in irrigated field.Results showed that changes of chlorophyll a and total chlorophyll were identical,and their peaks appeared at budding stage in leaf and at anthesis stage in stem respectively.Soluble sugar in leaf increased initially then decreased,and in stem it showed down-up-down trend.The peaks of soluble sugar accumulation appeared in leaf at anthesis stage and in stem at budding stage.The chlorophyll a,total chlorophyll,soluble sugar contents and their accumulation improved with increased nitrogen and phosphorus.Number of capsules per plant, number of seeds per capsule,1 000 -seed weight and yield in NP-fertilizer treatment increased by 27.97%, 16.13%,18.52% and 49.07% compared to CK respectively.
