青海共和地区藜麦种植的气象条件分析

Meteorological Condition Analysis of Chenopodium quinoa Plantation in Gonghe Area of Qinghai

利用2016年在共和地区的藜麦种植试验,得出共和地区种植藜麦的气候条件。共和地区藜麦生长期≥0℃积温为1 700℃左右,降水量250 mm,日照时数1 170 h,气象条件能够满足藜麦生长需求。开花期间的晴朗少雨天气对开花授粉有利,表现为空壳率少。藜麦开花期间温度适宜,降水日数少,日照时数日均达5.4 h,有利于藜麦开花。藜麦成熟后,在适宜的温度条件下,如果降水多,可导致种子发芽,因此收割期间多降水天气,对藜麦产量和品质有一定影响。播种期间的干旱少雨和收获期间的连阴雨天气是藜麦种植的一个不利因素。

The climatic conditions of Chenopodium quinoa grown in Gonghe area were obtained by using the C. quinoa planting experiment in the Gonghe area in 2016. The ≥0℃ accumulated temperature of C. qulnoa in the Gonghe area was about 1 700℃ , the precipitation was 250 mm, the sunshine hours were 1 170 h, and the meteorological conditions could meet the growth demand of C. quinoa. The sunny weather of the duration of flowering was beneficial to pollination, and the performance was the low full-empty shell rate. During the flowering period, the temperature was good, the number of days of precipitation was small, and the daily sunshine hours reached 5.4 h, which was beneficial to the flowering of C. quinoa. After the ripening of C. quinoa, if the precipitation was large, the seeds could be lead to germinate at the appropriate temperature conditions. So the abundent precipitation weather during the harvest period, had a certain impact on the yield and quality of C. quinoa. The drought weather during sowing and even rainy weather during harvest were unfavorable factors in the C. quinoa cultivation.
