摘要
为探究藜麦在北京浅山区的适应性及最佳播期,笔者以‘陇藜1号’为研究对象,开展从3月底至7月中旬共计8个播期的比较试验。结果表明:‘陇藜1号’在北京浅山区的最适播期为5月下旬,全生育期104天,株高153.6 cm,千粒重3.14 g,产量1781.25 kg/hm2,转色后可观赏18天,成熟时麦穗和茎秆都呈红色,全田景观效果好。与‘陇藜1号’生育日数相当的早熟型品种可于5月下旬在昌平延寿镇,乃至昌平、门头沟、密云、怀柔、平谷等海拔300 m左右、年平均气温与年平均积温与本试验点相近的浅山区示范种植。
The paper aims to explore the adaptability and optimal sowing date of quinoa in the shallow mountain areas of Beijing.We conducted a comparative test with 8 sowing dates from late March to mid-July by using the variety‘Longli-1’.The results showed that:the optimal sowing date for‘Longli-1’in the shallow mountain area of Beijing was late May;its whole growth period was 104 days,plant height was 153.6 cm,the 1000-grain weight was 3.14 g,and the yield was 1781.25 kg/hm2;the viewing period was 18 days;the ears and stalks of quinoa could all turn red when they were mature;the landscape effect of the whole farmland was fine.Premature varieties with similar breeding days as‘Longli-1’could be planted in Yanshou of Changping in late May,demonstration sites could be extended to Changping,Mentougou,Miyun,Huairou,Pinggu and other shallow mountainous areas with the similar elevation(300 m),average annual temperature and average annual accumulated temperature.
