摘要： 研究甜荞北旱生在内蒙古武川县(地处阴山北麓)不同氮、磷配施处理下赖氨酸和黄酮含量的变化，对于武川区域荞麦药用种植具有重要的指导意义。试验于2010年6月在内蒙古武川县上秃亥乡马铃薯种薯繁育中心进行，试验设氮、磷2个因素，作随机区组设计。测定荞麦现蕾期，盛花期，成熟期3个时期，荞麦茎，叶黄酮含量以及荞麦籽粒中黄酮和赖氨酸的含量。结果表明:在P₆N₈水平下，赖氨酸含量最高，达到120.14 mg/g，与对照相比增加了118.08%。在P8N8水平下，茎，叶黄酮含量最高，与对照相比，现蕾期分别减少了1.8%，2.7%；盛花期1.0%，8.6%；成熟期39.4%，12.7%。而荞麦籽粒，在P₆N₈水平下，黄酮含量最高，达到98.25 mg/g与对照相比增加了127.6%。

Abstract: Research lysine and flavonoids content of Beihansheng sheng buckwheat in Wuchuan xian of InnerMongolia ( Yinshan moutain) under different N， P treatments， for Wu Chuan regional buckwheat planting has important guiding significance． Test starts in potato seed breeding center， June 2010 Shangtuhai town of Wuchuan countyof Inner Mongolia． Test set nitrogen， phosphorus as two factors， make randomized to design． Test buckwheat stem，leaf flavonoid content and buckwheat grain lysine and flavonoids content in squaring stage， bloom stage， mature period． The experimental results show that， In P₆N₈ level， lysine reach the highest levels， 120． 14 mg /g， compared withCK， increased by 118． 08% ． In P8 N8 level， stems， and leaves flavonoids content get to the highest level comparedwith CK． Squaring stage reduced 1 ． 8% ， 2． 7% respectively; Bloom stage 1 ． 0% ， 8． 6% ; Mature stage 39． 4% ，12. 7% ． However， in P₆N₈ level， flavonoids of buckwheat grain achieve the highest content， 98． 25 mg /g， comparedwith CK increased by 127． 6% ． For Wuchuan develop their own special buckwheat industry provide certain theoretical basis， more develop local economy．

Key words: Nitrogen and phosphorus fertilizer, Dry farming buckwheat, North of Yinshan, Lysine, Flavonoids
