Abstract：To identify suitable growth regulators for sugar beets under drip irrigation in Xinjiang and improve the sugar beets yield,the effects of different plant growth regulators on agronomic traits,photosynthetic characteristics,yield of sugar beets were investigated.At 50,70,and 90 days after the emergence of sugar beets,four plant growth regulators DPC,CCC,S3307 and ETH,were sprayed three times on the sugar beets,with water as the control(CK),in 2021 and 2022.The results showed that plant growth regulators could effectively reduce plant height,increase photosynthetic pigment content in sugar beet leaves by 7.38％—16.81％and the net photosynthetic rate by 0.54％—21.54％.The four treatments could increase the yield of sugar beet by 5.97％,12.91％,2.84％,14.20％in 2021,and 10.46％,13.08％,8.39％,18.17％in 2022,respectively,compared with CK.The sugar production of the four regulator treatments was increased by 4.56％,10.90％,6.87％,10.35％in 2021,and 8.34％,11.87％,9.44％,0.43％in 2022.By combining PCA(principal component analysis)and entropy weighted TOPSIS comprehensive evaluation,the impact level of the four growth regulators on sugar beets showed CCC＞ETH＞DPC＞S3307＞CK.Overall,CCC was the best regulator in regulating the growth,yield,and quality of sugar beets.
