采用Design-Expert优化2种药剂对香蕉除芽效果最佳配比研究
Dosage Optimization of Two Disbuding Chemicals in Banana by Design-Expert Design
摘要
Abstract
The suckers from a mother plant of banana were used as the test material.On the basis of a single factor experiment,the experiment plan of the desuckering effect with mixed agents of potassium dihydrogen phosphate and paclobutrazol was designed using a Design-Expert 6.0 software.The desuckering effect of different mixture and the influence of the reagent on the banana mother plant growth was analyzed.Results of the interaction effect analysis and the best reagent proportion were predicted and verified in the field.Results showed among the 13 dose combinations of potassium dihydrogen phosphate and paclobutrazol in 1.5～8 g,the combination of 8 g potassium dihydrogen phosphate and 3.84 g paclobutrazol had the best effect on disbuding and promoting plant growth of banana.The mortality of banana sucker 3 days after was up to 100％.The treated suckers were wilted and rotten.The increasing rates of stem height and diameter 15 days after was up to 9.76％ and 6.94％.Therefore,potassium dihydrogen phosphate mixed with paclobutrazol in a ratio 2∶1 is recommended as an efficient,safe and economical desuckering agent.关键词
