| Abstract: | In order to better play the role of buckwheat in the landscape construction of Fangshan district, the sowing date experiment of buckwheat was carried out to study the effect of sowing date on the ornamental period and plant height of buckwheat. The results showed that the suitable sowing date for spring sowing of buckwheat in Fangshan District was April 5 to 16, and the blooming period was about 70 days, the duration from flowering to lodging were also about 70 days, the duration from closure to lodging were about 60 days, the duration from full flowering to lodging could last about 60 days, and the ornamental duration was the longest. The suitable sowing time for summer and autumn was from July 20 to August 25, the plant was not easy to fall, and the blooming period was 34 to 57 days, the best sowing time was about July 20 and the blooming period was 57 days.
