Abstract: Based on the analysis of the agricultural meteorological observation data of quinoa cultivated in Zhengning County from 2013 to 2017, this paper concluded the best way to get the full stand of seeding is transplanting the seeding to the field after cultivation in the greenhouse. It is suitable for seeding in late April, transplanting in late May, and harvesting in mid-late late August. The most important meteorological factor that affects the growth of quinoa is the temperature from transplanting to grouting period, when the temperature is high, the quinoa grows quickly. Sunlight can meet the need of the growth during the whole growth period. Precipitation has a negative effect on the growth during the whole growth period, while excessive precipitation is unfavorable to the growth of quinoa. Therefore, it is not suitable to plant quinoa in the Chuan Road area of Zhengning County and the adjacent Ziwuling where there is more precipitation, while the climate conditions of the plateau and mountainous area at the altitude of 1200m can meet the need of quinoa growth. The whole growth period of quinoa in Zhenging lasts for about 120 days from sowing to ripening, with 2212 ~ 2354 ℃ accumulated temperature ≥0 ℃, 879 ~ 970 hours sunshine, and 400 ~ 500mm precipitation. Although Zhengning is taken as an example in this paper, it has a good reference value for semi-arid and semi-humid quinoa region in Gansu Province.
