| 于2020年在新疆喀什新糖区采用大田随机区组试验设计，设置4个处理，其深松深度分别为：35 cm（S35）、45 cm（S45）、55 cm（S55），及未作深松处理（CK），研究不同深松深度对甜菜植株形态、作物产量形成的影响，并将甜菜形态特征与产量性状指标进行相关性及主成分分析。研究结果表明，S45、S55处理能提高甜菜单株绿叶数1.67～2.67个，且S55处理与CK处理相比显著提高了甜菜最大叶片长34.29%、最大叶片宽16.6%及最大叶柄长12.71%，为甜菜植株提供了较大的源, 促进了甜菜根直径、根围、根体长、根尾长及根尾质量的增长或增重，有效促进甜菜地下部生物量的积累，从而增加甜菜根冠比10.17%和生物量积累的15.15%。S45、S55处理单根质量和含糖率与CK处理相比分别增长了12.67%和10.20%，5.26%和8.33%，从而使S45、S55处理的甜菜产量和产糖量分别增长了14.71%和15.85%，20.75%和25.48%。主成分分析表明，深松条件下甜菜生长的主要指标为叶柄长、根冠比和生物量地下分配比例。在喀什新糖区深松深度为55cm可有效增加甜菜产量和产糖量。 |

| In this study, field randomized block design was adopted in Kashi New Sugar area of Xinjiang in 2020. Four treatments were set up. The subsoiling depth was 35 cm (S35), 45cm (S45), and 55 cm (S55), with no subsoiling as control (CK). The effects of different subsoiling depth on the morphological characteristics of sugarbeet and the formation of crop yield were studied. The correlation and principal component analysis of the morphological characteristics of sugarbeet were carried out, so as to provide the basis for constructing reasonable tillage depth of sugarbeet field in Kashi New Sugar area. The results showed that S45 and S55 increased the number of green leaves by 1.67~2.67. Compared with CK treatment, S55 treatment significantly increased the maximum leaf length by 34.29%, the maximum leaf width by 16.6% and the maximum petiole length by 12.71%, providing a greater source for sugarbeet plants. The root diameter, root girth, root body length, root tail length and root tail weight of sugarbeet were improved. The underground biomass accumulation of sugarbeet was effectively promoted, and the root shoot ratio and biomass accumulation of sugarbeet were increased by 10.17% and 15.15%, respectively. Compared with CK, the single root weight and sugar yield of S45 and S55 increased by 12.67%, 10.20% and 5.26%, 8.33%, respectively. The yield and sugar yield of sugarbeet increased by 14.71%, 15.85% and 20.75% and 25.48%， respectively. The results of principal component analysis showed that the main growth indexes of sugarbeet under subsoiling conditions were petiole length, root shoot ratio，and belowground biomass allocation ratio. In Kashi New Sugar area, the subsoiling depth of 55cm effectively increased beet yield and sugar yield. |
