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.

摘要: 为筛选适宜新疆滴灌条件下提高甜菜产量的生长调节剂,在2021、2022 年分别采用缩节胺(DPC)、矮壮素(CCC)、烯效唑(S3307)、乙烯利(ETH)4种植物生长调节剂在甜菜出苗后50、70、90 d进行3次喷施,同时以喷施清水为对照(CK),探究不同植物生长调节剂对甜菜生长、光合特性及产量的影响。结果表明,喷施植物生长调节剂能够明显降低甜菜株高,甜菜叶片光合色素含量较CK提高7.38%~16.81%,净光合速率较CK提高0.54%~21.54%,甜菜叶片光合物质生产能力得到了有效改善。2021年DPC、CCC、S3307、ETH 处理较CK 分别增产5.97%、12.91%、2.84% 和14.20%,产糖量较CK 分别提高4.56%、10.90%、6.87%和10.35%;2022年较CK分别增产10.46%、13.08%、8.39%和18.17%,产糖量较CK分别提高8.34%、11.87%、9.44%和0.43%。主成分分析和熵权TOPSIS综合评价表明,各生长调节剂对甜菜的效应大小依次为CCC>ETH>DPC>S3307>CK,矮壮素对甜菜生长发育及产量的调控效果最好。
