摘要:

为掌握藜麦在永昌的适宜性和种植过程中存在的问题,整理2017—2019年永昌藜麦生育期资料,结合气象资料和土壤养分实测资料,用对比分析法分析藜麦的生育期与气象条件之间的关系和造成藜麦减产的原因。结果表明:永昌藜麦全生育期为139天,整个生育期内所需的平均积温为2363.9℃,4月下旬是藜麦的最佳播种期;种植藜麦后的土地,氮、磷、钾的减少幅度较大,对耕地质量存在不良影响;播期推迟、连阴雨天气、种植土地未进行倒茬都是造成藜麦减产的原因;藜麦的种植要根据当地的实际情况因地制宜。

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.
