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
