Effects of Different Container Types and Substrates on the Growth of Amorpha fruticosa
In order to improve the container seedling technology of Amorpha fruticosa,a randomized block experi-ment design was used to study the effects of different seedling containers and substrates on the growth of Amorpha fruticosa seedlings through interaction effect and simple effect analysis,so as to select suitable seedling containers and substrates.The results showed that both container types and substrates had significant effects on the growth of Amorpha fruticosa seedlings,and the interaction between them also had a certain effect.The main effect showed that the plastic nutrition cup container could promote the growth of each index like seedling height,ground diameter,stem dry weight,root dry weight,main root length,total root length,average root diameter,root surface area,root volume and root diameter grade of Amorpha fruticosa.The mixed matrix of yellow soil and turfy soil is obviously better than the single yellow soil matrix,which can effectively ensure the growth of the aboveground and under-ground parts of the seedlings.The interaction effects of substrates and container types on Amorpha fruticosa were mainly manifested in ground diameter,stem mass,root stem mass and large diameter root growth.Therefore,the combination of plastic nutrition cup container and mixed matrix of yellow soil and turfy soil is more conducive to promoting the growth of Amorpha fruticosa seedlings.
