초록

This study was conducted to evaluate the growth rate of landscape trees produced in containers for three year, and the growth rate of the establishment period during sixth month~twelve months after transplanting. Two types of container such as plastic pot(pot) and fabric growing bag(bag) were adopted to restrict tree roots. Each type of container was divided into seven sub-types. One traditional production method was included as comparison. Two landscape woody plant species (Magnolia denudata, Albizzia julibrissin) were planted in the seven sub-types of container. After one or two growing season in the container, the trees of each container type were transplanted. Half of the trees were transplanted in the mild spring season, and the other half were transplanted in the improper summer season. The data was collected on the diameter of root cellar and the tree height in each year. The research results are as follows; 1. Container production method was lower than the traditional production methods by 1.3 times ~ 2 times in the growth rates. 2. The Geocell bag and Root control bag revealed higher growth rates than pp-woven bag. And pot- in-pot(double pot)system revealed higher growth rates than the ether container pot system in A denudata. There were no differences in the growth rates between container production system in Albizzia julibrissin. 3, The growth rates of improper transplanting trees was high in the \"pot\" type - \"bag\" type - \"control\" in descending order. Especially, the growth rates of \"pot\" type revealed higher than \"control\" by 4 times. 4. From the results of ANOVA and Ad hoc test, the variable of growth factors of each container types in improper transplanting experiment was not significant for a range of 5% or 1% level. And the growth rates of traditional production method was lower than the container production method. 5. There was no differences in growth rate between the containerized and the traditional production system in the case of proper transplanting experiment. The growth rates of diameter of root collar was higher in the \"control\". The growth rates of tree height was higher in the \"bag\" type. Finally, based upon the results of this study, subsequent research on the development of container materials and maintaining methods that focused on the growth rates would be required.aintaining methods that focused on the growth rates would be required.
