摘　　要：为探究呼和浩特地区春季胡萝卜的最适播期,以胡萝卜H1306为试材,设置4月25日、5月5日、5月15日、5月25日、6月4日和6月14日6个不同播期,比较分析了胡萝卜的先期抽薹情况、经济性状及产量等指标。结果表明:播期越早,先期抽薹率越高,对胡萝卜品质和经济性状影响越严重。6月4日和6月14日播种的胡萝卜先期抽薹率分别为4.1%、3.7%,均显著低于其他播期,且平均单根质量、根长、根粗及商品产量等各项指标表现均优于其他播期。综合分析得出,呼和浩特地区胡萝卜春季露地播种不宜早于5月25日,否则会发生先期抽薹现象,严重影响产量和品质。In order to explore the most suitable sowing dates of carrots in Hohhot district in spring,six different sowing dates were set up on April 25th,May 5th,May 15th,May 25th,June 4th and June 14th,and the early bolting,economic traits and yield of ‘H1306’ carrot were compared and analyzed.The results showed that the earlier the sowing date,the higher the early bolting rate,and the more serious impact on the quality,yield and traits of carrots.The early bolting rate of carrots sown on June 4th and June 14th were 4.1% and 3.7%,respectively,which were significantly lower than other sowing dates,and the average single root weight,root length,root diameter and commercial yield were all better than that of other sowing dates.A comprehensive analysis showed that the sowing date of carrot in Hohhot area in spring should not be earlier than May 25th,otherwise the phenomenon of early bolting would occur and the yield and quality would be seriously affected.
