采用方差分析法研究噻苯隆对棉花的脱叶、吐絮影响，利用相关性分析法和灰色关联度分析法研究噻苯隆与棉花产量和农艺性状的关系。方差分析结果表明：50%噻苯隆可湿性粉剂在150～450 g/hm2施药剂量下，对棉花脱叶、吐絮效果显著。灰色关联度分析法表明：受噻苯隆影响较大的性状因子主要是籽棉产量，与相关性分析结果噻苯隆与籽棉产量呈极显著正相关一致；噻苯隆与子指、比强度关联度不大，与相关性分析结果噻苯隆与子指、比强度呈显著负相关有一定的差异。

Variance analysis was employed to investigate the effects of defoliation, boll opening of thidiazuron 50%WP on cotton. The correlation analysis and grey correlation degree analysis were employed to investigate the correlation of thidiazuron with agronomic traits, cotton yield. The results of variance analysis showed that at the dosage of 150-450 g/hm2 of thidiazuron 50%WP, the effects on defoliation and bol opening of cot on were remarkable. The results of grey correlation degree analysis showed that the seed cot on yield was greatly affected by thidiazuron, which was accordance with the results of the correlation analysis, the significant positive correlation existed between thidiazuron and the seed cot on yield. The correlation degree was not high between thidiazuron and seed index, specific strength, which was different with the results of correlation analysis, the negative correlation existed between thidiazuron and the seed index, specific strength.
