Abstract:

To grasp the suitability of quinoa in Yongchang and the existing problems in the cultivation process, we collected the growth period data of Yongchang quinoa from 2017 to 2019, combined with meteorological data and soil nutrients’ data, to analyze the relationship between the growth period of quinoa and meteorological factors and the reasons for the yield reduction of Yongchang quinoa. The results show that the whole growth period of Yongchang quinoa is 139 days, and the average accumulated temperature required during the whole growth period is 2363.9℃. Late April is the best seeding time for quinoa, and after the cultivation of quinoa, the reduction of soil phosphorus and potassium is obvious, which has a negative impact on the quality of cultivated land. Delayed sowing, rainy weather, and no crop rotation after quinoa cultivation are all reasons for quinoa yield reduction, so the cultivation of quinoa should be based on local conditions.
