Study on the Effect of Mechanical Manipulation on the Regulation of Pepper Seedling Plant Type
[Objective]To reveal the effects of different agitation treatments on chili seedlings,and to provide physical regulation of plant type patterns and technical support for reducing seedling elongation and cultivating strong seedlings.[Method]The effects of different times and frequency of agitation on the morphological indicators,photosynthetic characteristics,stem mechanical properties,and endogenous hormones of"Jiaolong 2"were studied.[Result]T3 treatment could significantly reduce seedling height,increase seedling stem diameter,improve seed-ling vigor index,photosynthetic characteristics,and stem mechanical properties.[Conclusion]After principal component analysis,the most suitable strategy for regulating the plant type of chili seedlings was T3 treatment,which involved stirring 90 times a day and stirring 45 times at 08:00 and 14:00 respectively.
