Effects Of Different Foliar Fertilizer On Main Characters Of Platycodon Grandiflorum

In order to solve the related issues in the process of artificial cultivation and the agronomic traits of Platycodon grandiflorum, In this study, the tentative have made foliar fertilizer on Platycodon grandiflorum. To choose12kinds of commonly used foliar fertilizer(Li duo feng, Yi bian shen fei, Si ji lv ge, Jia bao, Gao gai, Xiao ye di, Peng da su, Lin suan er qing jia, Jin bao lai, Huo li su, Ye fei). Treatment starting from the four leaf stage of Platycodon grandiflorum regularly spraying processing, investigating the main agronomic traits in the fall.Based on this,chooses6kinds of foliar fertilizer, Gao gai, Xiao ye di, Jia bao and Si ji lv ge can promote root length, Yi bian shen fei and Li duo feng can increase the stout, then cross combination. To grasp the Combination about different kinds of foliar fertilization effect on the characteristics of main agronomic traits. Then to provide a theoretical basis for screening foliar fertilizer is suitable for the large-scale cultivation of Platycodon grandiflorum.Through experiment and analysis the results get the following conclusion:1、After processing different kinds of foliar fertilization, characteristics of the plant height, stem diameter, branch number, stem and leaf fresh weight, root length, stout,lateral root number, root fresh weight between these traits and CK significant or extremely significant difference.2、To deal with different kinds of foliar fertilization experiment, Xiao ye di, Gao gai, Jia bao,Si ji lv ge performed better in terms of root length, Yi bian shen fei, Li duo feng in terms of has performed well.3、Cross combination after processing, characteristics of the plant height, branch number, aboveground fresh weight, leaf fresh weight, fruit fresh weight, root length, root thick, lateral root number, root fresh weight between these traits and CK there are significant or very significant difference.4、Li duo feng/Xiao ye di the best comprehensive performance, especially in the characteristics of the underground part of traits, which can promote root length, reduce the lateral root, increase root fresh weight at the same time.5、Yi bian shen fei/Gao gai has good performance in various characters, but the downside is that more lateral root.6、Yi bian shen fei and Xiao ye di combination did not play the advantage in root and lateral root number.7、Yi bian shen fei combined with Si ji lv ge treatment than single treatment effect is bad.8、Yi bian shen fei combined with Jia bao than single treatment performance general, no play their respective advantages of both in individual character.
