本文以 4种 ABT剂型和 6种剂量对棉种进行处理 ,通过聚类分析和对子棉产量的正交多项式回归分析 ,结果表明 :ABT各剂型处理棉种的增产效果极显著 ,剂型不同 ,处理效果不相同 ,4种 ABT剂型的最佳剂量分别为 ,ABT6 :1 3.80 mg· kg- 1;ABT7:2 3.50 mg· kg- 1;ABT8:2 7.86mg·kg- 1;ABT10 :2 2 .2 2 mg· kg- 1,其中 ABT7效果最好 ,拟合的模型为 :Y2 =3647.32 1 7+ 2 7.62 50 X-0 .5877X2 ,有极显著相关的非线性回归。
In this paper, four kinds of ABT dosage forms and six kinds of dosage of cotton seed processing, by cluster analysis and orthogonal polynomial regression analysis of the yield of cotton, the results showed that: ABT each dosage form cotton yield stimulation effect is extremely significant, different dosage forms, The best dosage of the four ABT dosage forms were ABT6: 1 3.80 mg · kg-1, ABT7: 2 3.50 mg · kg-1, ABT8: 2 7.86 mg · kg-1, ABT10: 2 2 .2 2 mg · kg-1, of which ABT7 had the best effect. The fitting model was: Y 2 = 3647.32 1 7+ 2 7.62 50 X-0 .5877X2, and there was a very significant nonlinear regression.
