For this purpose, research was made to look into the style, material, organization, and legal as well as institutional system of the bonsai industry in the three countries. In order to understand what significance it has and how it has changed historically, related literature was surveyed and questionnaires were distributed to the concerned people to collect the data needed for them to plan bonsai industry. The results of the survey are as follows. Analysis of awareness of bonsai culture, respondents replied that the motive and purpose of bonsai is because they like flower trees, and the technical information about bonsai is usually obtained by visits to bonsai gardens. The analysis revealed that respondents usually join more than one bonsai club and are active more than once a month, which means longer than 4 hours each month, and their activities are more frequently in the metropolitan area. From the analysis of preference for bonsai culture, it was made known that the favorite bonsai size is less than middle one(20~50cm), the characteristics of the favorite species are beauty. A research and analysis of bonsai-related technical education found that bonsai is trimmed manually in general, bonsai experts are usually kept in contact with, and the bonsai technique is learned through interaction with the experts.

Bonsai is part of export forest products in Korea. Demand for bonsai exports to other countries is growing but the need for quarantine hazards must be eliminated in other to export. Plant parasitic nematode is also an important factor in quarantine. The nematodes were surveyed from bonsai farms in 6 areas of Korea. The surveyed deciduous bonsai plants were Acer palmatum, Zinnia elegans, Ligustrum obtusiflium, Carpinus turcaninowii, and Malus sieboldii. Three plant parasitic nematodes (Hemicyliophora koreana, Rotylenchus blothrotylus and Xiphinema americanum) and three non-parasitic nematodes (Aporclaimellus donghwaens, Egtitus andhricus, and Mesodorylaimus usitatus) were isolated from bonsai. Non-parasitic nematode, Mesodorylaimus usitatus was isolated from all surveyed bonsai trees. Only two species of quarantine nematodes (Hemcylicopora koreana and Xiphinema americanum) were found from bonsai. A. donghwaens and M. usitatus were isolated from root of bonsai tree. However other nematodes were isolated from soil in bonsai trees.

There have been some problems of high labor. low productivity in the existing systems of bonsai cultivation. This study was conducted to cultivate a large quantity of hig-quality bonsai through the development of bottom irrigation system and management method. Bonsai placed on the FRP bed were grown very well by bottom irrigation system compared with direct watering and sprinkler system. It was concluded that bottom irrigation system was possible to reduce considerable manual labor and produce mass production of high-quality bonsai within shorter periods. This research was finally found that the growth was significantly better and earlier production was certain in the vinyl house, had another advantage which could cultivate less cold-resistant species and therefore broadened a range of species selection for market supply. Cultivation techniques by the use of vinyl house and bottom irrigation system developed was quite effective for early production of bonsai as well as for high productive and value added. This project developed a new practical techniques and systems which can make mass and early production of bonsai with high quality through input of less labor. Interest in bonsai is now expanding in landscape horticulture and other fields concerned, and bonsai export of our country is also increasing. Results from this research will make a great contribution to enhancing of bonsai cultivator's competitive position in world markets and to improving of their annual income.

Anoplophora chinensis and A. glabripennis is classified as important quarantine Cerambycidae beetles worldwide. These beetles cause serious damage on natural host plants and export bonsai trees in Korea. We evaluated efficacy of phosphine fumigant for control of two Cerambycidae beetles in bonsai. In the preliminary test to achieve CT (Concentration x time) values of phosphine to Cerambyicdae beetles larvae, we used Monochamus alternatus of larvae as an alternative insect. A 24 h phosphine fumigation with $2g/m^3$ phophine achieved 100% eggs mortality against Anoplophora chinensis and A. glabripennis. Larva of A. chinensis was also completely controlled when treated for 168-h at same dose desiccator. 100% mortality on larval stage of two beetle species were achieved both in dormancy (January) and vegetative period (February) of bonsai when treated with $2g/m^3$ phosphine. However, phosphine fumigation against vegetative period of Acer palmatum, Carpinus turczaninowii and Malus sieboldii bonsai showed slight phytotoxicity (shorten leaf and flower size and delayed flowering).
