摘　　要：2022年定点调查表明,重茬、晚播甜菜R/T比值小,含糖低;距离滴灌支管在5.0米范围内KWS1197(高、绿)甜菜R/T比值小,含糖相对低,而远离滴灌支管KWS1197(矮、黄)甜菜R/T比值大,含糖相对高;丰产型品种KWS2314和高糖型品种MA097,R/T比值大,含糖都比较高;2023年大田调查表明,坝上及毗邻区甜菜含糖不高。随着调查时间的推迟,甜菜平均单株块根重增加、平均单株地上部重减少或稳定、R/T比值增加、含糖增加。甜菜在不同锤度范围的甜菜样本数量分布频率与锤度范围之间有如下关系:正偏态分布、负偏态分布、正态分布、幂指数关系。A fixed-point survey in 2022 showed that the R/T ratio of continuous cropping and late sown sugar beets were small and the sugar content was low;Within a range of 5.0 meters from the drip irrigation pipe,KWS1197(high,green)sugar beets have a small R/T ratio and relatively low sugar content,while KWS1197(short,yellow)sugar beets far from the drip irrigation pipe have a large R/T ratio and relatively high sugar content;The high-yield variety KWS2314 and the variety MA097 with high sugar content have a high R/T ratio and high sugar content;The 2023 field survey showed that sugar content of sugar beets in Bashang and adjacent areas is not high.As the investigation time was delayed,the average root weight per plant of sugar beet increased,the average above-ground weight per plant decreased or stabilized,the R/T ratio increased,and the sugar content increased.The distribution frequency of sugar beet sample number in different Brix ranges has the following relationship with the Brix range:positive skewed distribution,negative skewed distribution,normal distribution,power exponential relationship.
