| 摘 要： | 运用三因素五水平二次正交旋转组合设计，研究了赤霉素、烯效唑和抑芽敏对苎麻茎秆抗倒伏性及其抗倒指数的影响，建立了相应的数学模型：Y=87.10-9.03X1+8.30X2 -9.41X12-12.25X32。经模拟选优得出，当赤霉素取14.29 mg·kg-1，烯效唑取20.00 mg·kg-1，抑芽敏取357.00 mg·kg-1时，抗倒指数达最大值103.23 g·mm-1，这个方程可作为反馈试验及大面积推广应用的基础。 |

| Abstract: | The orthogonal rotated combination design on the basis of three factors and five levels was used to investigate the effects of GA3, uniconazole and prime on resistance to lodging resistance and lodging-resistant index of ramie culm. A mathematical model was established as: Y=87.10-9.03X1+8.30X2-9.41X12-12.25X32. It was concluded from the model that when GA3, uniconazole and prime were used at the dosages of 14.29 mg·kg-1, 20.00 mg·kg-1 and 357.00 mg·kg-1 respectively, the lodging-resistant index was the highest(103.23 g·mm-1). The model would be a foundation for feedback trial and popularization. |
