As the spreading of abandoned bamboo forests is becoming a serious problem in Japan, new possible uses for bamboo biomass are being sought toward controlling their further spread. In the present study, we investigated the potential of bamboo powder substrates in cultivation of horticultural plants as well as for bamboo powder to be used as a soil supplement in potting substrate recycling. Twenty varieties of ornamental flowering species were sown either in a conventional potting substrate or bamboo powder substrates. After 30 days, the cumulative germination rate of each variety was not affected by the type of substrate the plants were grown in. Although the overall plant growth of pot French marigold, pansy, and strawberry showed a tendency of being inferior in the bamboo powder substrates compared with the conventional potting substrate, it was improved by the addition of compost. The growth of French marigold also improved when the fermented bamboo powder substrate was additionally fertilized. We found that the microbiota present in the recycled potting substrate containing fermented bamboo powder was similar to that found in fresh potting substrate. These results indicate that bamboo substrate has great potential to be employed both as a growing substrate for various garden plants and as a soil supplement in recycling of used potting substrate.
In Japan, it is known that the reason for the new value of the landscape of deciduous broad-leaved forests such as Quercus serrata was in the literature of the latter half of the Meiji era. However, there is no study that organizes what kind of literary work and what kind of expression formed the values for the landscape of deciduous broad-leaved forests such as Quercus serrata. This study clarified this part. As a result, I found expressions related to deciduous broad-leaved forests such as Quercus serrata in the following literary works. Ivan Sergeevich Turgenev " The Rendezvous "translated by Futabatei, Shimei (1896), Kunikida, Doppo "Musashino"(1898), Tokutomi, Roka"Shizen to Jinsei " [Nature and man] (1900) "Mimizu no tawagoto " [Ramblings of an earthworm] (1913), Tayama,Katai"Shincha no kaori "[New tea incense] (1909), Shimazaki, Toson "Chikuma Sukecchi "[Chikuma River sketch] （1913）. Today, the feeling we feel when we see deciduous broadleaved forests such as Quercus serrata is formed by the above-mentioned literary works, and the background is the influence of Romantic literature that begins in Western Europe.
We report on the practice of the actions for SDGs in Awaji Landscape Planning and Horticulture Academy and the verification of its results. We decided to promote SDGs in human resource development, community activities and campus management by reflecting the opinions of faculty members and students through workshops and questionnaires. The creation of faculty and student volunteer teams and a wide range of voluntary initiatives contributed to the realization of many of the SDGs. In addition students have led to the development of human resources who will contribute to the construction of a sustainable society through the process of participating in these efforts.
"Gossa Kaito remains" is a remains of the Yayoi period. The remains has been maintained to open as a remains park, and needs a plan for planting design in the park. In this project, we planned and carried out planting events mainly to contribute for learning the history and environment. This project is collaborated with Awaji city as administration and local residents. Considering environment and maintenance situation of the remains, we used plants in Yayoi period and plants in region to express regional characteristics. Through the consultation between administration, local residents, and experts, carried out events of the planting two times. According to result of questionnaire survey, people had a high evaluation for the planting events. Thus, thought carrying out process of maintaining park such as planting with local residents is good for interaction and learning. In future, it is important to continue planting in "Gossa Kaito remains" to cooperate and gain the understanding with administration, local residents more.
Parks have various open spaces such as grassy areas and shady trees. These spaces are used for a variety of activities. On the other hand, parks are also expected to have the potential for static use, where people can enjoy their time and refresh their bodies and minds. We focused on reading activities as a program to generate such use in open spaces such as lawns and shaded areas. We divided the project into three phases and conducted practical trials. In addition, we explored the relationship between the library, the plaza and roads, and tried to find out what kind of measures would promote such activities. As a result, we found that the "Green Library" was better promoted in areas slightly off the park road, near the playground equipment, and on the grass. We also examined the effectiveness of reading to children and the presence of staff. The results of the study revealed more effective ways of introducing the "Green Library" and points to be noted for its promotion.
The aim of this study was to improve the quality of Hydrangea in a factory that is manufacturing flowers for preservation uses and investigate the effects of training on the yield and quality of cutting Hydrangea for preserved flowers. We conducted researches for making a year’s maintain plan the Hydrangea; collecting data about weather and soil around the site and inspecting insects and diseases that are causing a decrease on the one’s yield. Inspecting one’s quality and quantity of the flower, a number of branches in the sample plants were restricted to 20, 30 and 40 in the previous year and 20 and 30 in the current year. The number of shoots and inflorescences were the highest in the plant samples restricted to 40 shoots in the previous year and the number of inflorescences per shoot was the highest in the one restricted to 20 shoots in the current year, whereas the lowest was observed in the one restricted to 20 shoots in the previous year. The size of the inflorescence was the largest in the plant samples restricted to 20 shoots in the current year, and the least was in the one restricted to 20 shoots in the current year. A positive correlation was found between the diameter of the inflorescence axis and the size of the inflorescence and the sepal thickness of the antique decorative flower. We also experimented with the sections were reduced one's shoot growth and a number of times pruning to examine the difference in one's height. The growth rate was higher reduced in shorter size than one's in a longer size
