조춘 저온기에 혼반용대두(풋콩)을 조기재배하는 경우 다수가능한 재식거리 및 질소질비료 시비적량을 구명하기 위하여 온상내에서 단일처리(1일 11시간)를 하고 오개수준의 재식거리 및 4개수준의 질소시비량(각 구 공히 인산과 가리는 표준시비량 시용)을 조합 적용하였다. 품종은 조생종인 북해일호를 공시하였으며 그 시험 결과를 요약하면 다음과 같다. (1) 일주당 협수, 입수, 및 분지수를 많이 착생시키기 위해서는 재식거리를 50cm$\times$10cm 및 30cm$\times$20cm 등 비교적 넓게 하는 것이 효과적이었으나 단위면적당 꼬투리 및 알맹이의 증수를 위해서는 오히려 평당주수가 월등히 많은 50cm$\times$5cm 및 30cm$\times$10cm 등 재식거리를 좁게 하는 것이 효과적이었다. (2) 단위면적당 꼬투리 및 알맹이의 다수를 위한 질소질비료의 시비적량은 표준시비량만으로 충분하다는 사실을 인정하였다.

Objectives: This study was conducted in order to evaluate personal and area exposure to airborne total dust and endotoxin during harvest and planting tasks at cucumber, yellow melon and potato farms Materials and Methods: Total dust was measured with NIOSH method 0500. Endotoxin were measured using a 37 mm glass fiber filter which was connected to an air pump calibrated to 2 LPM, and then analyzed with a Turbidmetric kinetic method. Results: The average(arithmetic mean) concentrations of total dust in the personal samples were $0.10-3.81mg/m^3$ for cucumbers, $0.21-1.19mg/m^3$ for yellow melon, and $0.08-2.72mg/m^3$ for potato. There was a significant difference in the harvest task among the three farm types(p=0.019 of personal sample, p=0.048 of area sample), in which the air concentration for potatoes was higher than with cucumbers and yellow melons. Conclusions: It was found that potatoes(planting and harvest) should be considered the first priority for studying and reducing total dust exposure.

This study aimed to select evergreen broad-leaved trees (EBT) that can be produced and planted in Korea by analyzing the current use of the trees for landscaping in the Kyushu area of Japan, a warm temperate region. The results revealed the total production of EBT was higher than that of conifers and due to the suitable growth environment of the area and the subsequent high demand for them. The landscape tree production methods in Japan were divided into container nursery and outdoor nursery, and the uses and species of the trees varied depending on the method; a variety of native species were produced in container nursery rather than in outdoor nursery, whereas trees used as ornamental, gardening, and shade plants were produced in outdoor nursery rather than in container nursery. The results also showed that in Fukuoka, a major city in Kyushu that is adjacent to Korea, the planting rate of EBT, used as ornamental, gardening, and shade plants, was higher than that of deciduous broad-leaved trees and conifers. In the city, the planting rate of Cinnamomum camphora was the highest, Elaeocarpus sylvestris var. ellipticus, Ternstroemia gymnanthera, Ilex rotunda, Quercus glauca, Camellia sasanqua, Eurya emarginata, Pittosporum tobira, Raphiolepis indica var. umbellata, Hedera rhombea, Kadsura japonica, Trachelospermum asiaticum var. asiaticum. These species were verified in Kyushu area for their application as landscape trees and are expected to serve as landscape trees in Korea if the planting areas of them are expanded by global warming, urban heat island and regional microclimate.

Background: Glomus intraradices is a species of arbuscular mycorrhizal fungi that, as an obligate endomycorrhiza, can form mutually beneficial associations with plants. Panax ginseng is a popular traditional Chinese medicine; however, problems associated with ginseng planting, such as pesticide residues, reduce the ginseng quality. Methods: In this experiment, we studied the effect of inoculating G. intraradices on several physiological properties and microbial communities of ginseng. UV-Visible Spectrum method was used to detect physical properties. Denaturing gradient gel electrophoresis method was used to analyze microbial communities. Results: The results indicated that inoculation with G. intraradices can improve the colonization rate of lateral ginseng roots, increase the levels of monomeric and total ginsenosides, and improve root activity as well as polyphenol oxidase and catalase activities. We also studied the bacterial and fungal communities in ginseng rhizospheric soil. In our study, G. intraradices inoculation improved the abundance and Shannon diversity of bacteria, whereas fungi showed a reciprocal effect. Furthermore, we found that G. intraradices inoculation might increase some beneficial bacterial species and decreased pathogenic fungi in rhizospheric soil of ginseng. Conclusion: Our results showed that G. intraradices can benefit ginseng planting which may have some instructive and practical significance for planting ginseng in farmland.

This study investigates, analyzes, and summarizes Dansplantation techniques and methods through practical methodology centering on fieldwork in order to present effective planting methods for large trees that have important significance. The conclusions are as follows : 1. The transplantation process of a large tree generally consists of the stages of digging up a tree, manufacturing a carrier frame, loading the tee on a vehicle, transporting, transplanting the tree, installing a strut and maintaining and managing the new transplant. In addition, planting a tree on a mounted place includes the primary procedures of trimming out the root, and preparing for transplanting the tree on a mounted place, as well as the secondary work of trimming out the root, transplanting a tree on a mounted place, maintenance and management. 2. In order to decide on a transplantation method for a large-sized tree, a structure calculation has to be performed first. That is, one must calculate the weight of the tree and the allowable stress of the strut (H-beam, etc.) fhst and then decide on the upper method through computer modeling based upon this structural calculation. 3. As a result of the analysis of a transplanted tree using the life soil method, it was confirmed that large quantities of feeder roots had developed around the root within a short time after the transplantation. The life soil method has proven to be very effective for transplantation of large-sized trees. 4. As for the production method of an H-beam strut frame, it was found that the manufacturing process and disassembly process were simple and proper; therefore, the H-beam frame is an appropriate structure to be used in the transplantation of large trees. 5. The concavo-convex method, which consists of filling the life soil in the concavo-convex area around the root, was found to be a method that promotes the growth of feeder roots within a short period of time and saves the supply of water at the same time.

This study is carried out for obtaining the basic materials for presentation of creation and desirable management of urban roadside trees through analyse the existence effect of trees on people who operate th commercial areas along the streets. Roadside tree and green areas are recognized comfort space in addition to simple planting area. Therefore various trees and flowering plants should be introduced in addition to roadside facilities for convenience. Planted roadside trees should be maintained. We will propose an method that residents plant and manage the trees and flowering plants on the two lane of one way road. However main lines more than four lane of one way have more public property beside the residents space. Therefore these should be maintained mainly by related government agencies.

Rice farmers can save labor and expenses by using expanded rice husk (ERH) as a seedling medium since ERH is lighter and cheaper than other commercial seedling media (CSM). This study was carried out to develop a method for rice seedling cultivation using ERH as a seedling medium. It is suggested that a mixture of $60\%$ of ERH and $40\%$ of a CSM could be used as a seedling medium; the planting densities would be 240g per tray for infant seedlings and 200 g for young seedlings; and nitrogen (N) would be applied at a rate of 1g per tray for infant seedlings prior to planting and 2g per tray for young seedlings with division. Great care should be taken to use $CO(NH_2)_2$ as an N-source fertilizer. These results would lay a foundation for the rice seedling cultivation with ERH as a medium.

This study is about apartment greening to improve urban environment. To achieve this, questionnaires concerning the planter preferences were distributed. To improve perpendicular greening methods for apartments, MOCT (The Ministry of Construction and Transportation) reformed the law to obligate constructors to make apartment planters in June, 2000. But apartment residents take negative attitudes to making green space. It is difficult to manage the planters as well, so it is necessary that the point at making green spaces at apartments be scrutinized through questionnaires and an active method for making and managing the planter be made. The results show that apartment residents are reluctant to pay the expenses for planting and managing planters and have negative attitudes about plant purchases. If planting and managing of simplified planters are continually entrusted to residents, even vertical landscapes will be affected by illegal diversion and negligence as a result. Therefore, support from governments and local administrations are needed and legal obligation should be imposed on construction companies to install irrigation facilities.
