摘　　要：为探究大理州不同海拔条件下播期对红七星大蒜性状及产量的影响,在宾川县(1424 m)、弥渡县(1670 m)、鹤庆县(2177 m)3地设置5个播期(间隔15 d)开展试验。试验结果表明,随播期推迟,大蒜全生育期缩短;弥渡县、宾川县独头率呈下降趋势,鹤庆县则上升。弥渡县播期3(10月10日)产量和产值最高(10045.96元/667 m^(2)),不宜晚播;宾川县播期3产量最优,产值达16520.67元/667 m^(2);鹤庆县播期5(11月9日)独蒜产量最高(1382.45 kg/667 m^(2)),但播期4产值最佳(13951.03元/667 m^(2))。综合表明,海拔差异明显影响大蒜适宜播期,低海拔区宜早播,高海拔区宜晚播,可优化独蒜产量和经济效益。In order to explore the effects of sowing dates on the traits and yield of Red Seven-star garlic at different altitudes in Dali Prefecture,five sowing dates(interval of 15 days)were set up in Binchuan(1424 m),Midu(1670 m)and Heqing(2177 m).The results showed that the whole growth period of garlic was shortened with the delay of sowing date.The single-clove rate decreased in Midu and Binchuan,but increased in Heqing.In Midu,the yield and output value(10045.96 per 667 m^(2))of sowing date 3(October 10)was the highest,indicating unsuitability for late sowing.In Binchuan,the yield of sowing date 3 was the highest,and the output value was 16520.67 per 667 m^(2).In Heqing,the single-clove garlic yield of sowing date 5(November 9)was the highest(1382.45 kg/667 m^(2)),while the output value of sowing date 4 was the highest(13951.03 yuan per 667 m^(2)).These findings suggested that the difference in altitude significantly affected the suitable sowing date of garlic.Early sowing in low altitude areas and late sowing in high altitude areas could optimize the yield and economic benefits of single-clove garlic.
