  • After examining the viewpoints of the mental cultivation of The yellow Emperor's Internal Bible(內徑), from the viewpoints of The yellow Emperor's Internal Bible, I studied the principles and methods of the mental cultivation(精神養生) which the Taoism School, the Confusian School and the past physicians proposed. And I studied the methods of mental cultivation of the child, the woman and the old by the differences of ages and sex. At the subject of health preservation(養生學) on the basis of concept of relevant adaptation of man to nature(天人相應思想), the mental cultivation(精神養生) was regard more important than the body cultivation(肉體養生) and it was considered that the success of health preservation depended on the state of mind. the basic principles of the mental cultivation is achivement of the mental internal keeping(精神內守) through the state of peace and tranquility without avarice and wild fancy(恬憺虛無). The ways of mental cultivation of the Taoism School, the Confusian School and the past physicians were in the category of The yellow Emperor's Internal Bible. 4. In the previous Jin dynasty(先秦時代), the important theoretical bases and practices to mental cultivation were made. In the Han dynasty(漢時代), the physicians attached importance to mental treaments. During the time from Sui dynasty to Tang Dynasty(隋唐時代), the mental cultivation was made perfect theoretically. During the Period from Song dynasty to Yuan Dynasty(宋元時代), Many methods of mental cultivation were newly created. During the Ming and the Qing Dynasties(明淸時代), the theory of health preservation and the methods of mental treaments were embodied. 5. Studying the mental cultivation by the differences of ages, the childhood(小兒期) is the spring of life. So the mental cultivation of this period put importance to the cultivation of Sh ng(養生). And the youth(靑年期) is the summer of life. So the mental cultivation of this period pill importance to the cultivation of Ch'ang(養長). And the middle age(中年期) is the autumn of life. So the mental cultivation of this period put imporance to the cultivation of Shou(養收). And the old age(老年期) is the winter of life. So the mental cultivation of this period put importance to the cultivation of Tsang(養藏). Studying the mental cultivation by the differences of sex, the man must do the mental cultivation through the dynamic nature(性情) of Yang(陽) and the woman must do the mental cultivation through the static nature of Yin(陰).

  • To select the forage millet variety suitable for cultivation in the reclaimed tideland, forage yield and feed value were compared for six millet cultivars grown at the Dae-Ho reclaimed tideland, Korea, from March to October in 2004. The emergency rate of summer green was 95.0% which was more than those of any other vatieties. Fresh and dry matter yield of summer green were 21,444 and 5,296 kg/ha that were more than those of any other vatieties. respectively. The content of crude protein was the highest in Shirohie variety as 18.22%. TDN (total digestible nutrient) content was the highest in Siberian variety and the lowest in Panorama variety. Considering the emergency rate, forage production and feed value, Summer green was the most suitable variety in reclaimed tidelands.

  • Differences among cultivars, conditions of nutrient solution, nursing materials, and soilless culture systems were investigated to select suitable cultivar and cultivation methods for stable production of summer spinach in the highlands. The 'Quinto' spinach showed the earliest growth and highest yield. For yield increase of summer spinach, optimal solution pH was 6.0, EC was $2.0dS{\cdot}m^{-1}$, and $NH_4-N$ ratio of nutrient solution was 30 percent Stand rate of spinach in nursing seedlings, at 200-cell-tray filled with mixed nursing soil (peat : perlite = 7 : 3), was higher than those grown in urethane sponge and rock-wool plug. Yield was also 18 to 24 percent higher than those in rock-wool plug and urethane sponge. Plant length and yield of spinach in mixed substrate (peat : perlite = 7 : 3) filled nutrient film technique (MSNFT) system were longer of 18 percent, and higher of 9 percent than those in deep flow technique (DFT) system, respectively. However, changes of root zone temperature, pH and EC showed similar pattern with DFT. Therefore, growing 'Quinto' cultivar at 6.0 of pH, $2.0dS{\cdot}m^{-1}$ of EC, 30 percent of $NH_4-N$ ratio, at 200-cell-tray filled with mixed nursing soil, and MSNFT cultivation system, was the best for production of summer spinach in the highlands.

  • BACKGROUND: Generally, nitrogen (N) fertilization higher than the recommended dose is applied during vegetable cultivation to increase productivity. But higher N fertilization also increases the concentrations of nitrate ions and nitrous oxide in soil. In this experiment, the impact of N fertilization was studied on nitrous oxide ($N_2O$) emission to standardize the optimum fertilization level for minimizing $N_2O$ emission as well as increasing crop productivity. Herein, we developed $N_2O$ emission inventory for upland soil region during red pepper and Chinese milk vetch cultivation. METHODS AND RESULTS: Nitrogen fertilizers were applied at different rates to study their effect on $N_2O$ emission during red pepper and Chinese milk vetch cultivation. The gas samples were collected by static closed chamber method and $N_2O$ concentration was measured by gas chromatography. The total $N_2O$ flux was steadily increased due to increasing N fertilization level, though the overall pattern of $N_2O$ emission dynamics was same. Application of N fertilization higher than the recommended dose increased the values of both seasonal $N_2O$ flux (94.5% for Chinese cabbage and 30.7% for red pepper) and $N_2O$ emission per unit crop yield (77.9% for Chinese cabbage and 23.2% for red pepper). Nitrous oxide inventory revealed that the $N_2O$ emission due to unit amount of N application from short-duration vegetable field in fall (autumn) season (6.36 kg/ha) was almost 70% higher than that during summer season. CONCLUSION: Application of excess N-fertilizers increased seasonal $N_2O$ flux especially the $N_2O$ flux per unit yield during both Chinese cabbage and red pepper cultivation. This suggested that the higher N fertilization than the recommended dose actually facilitates $N_2O$ emission than boosting plant productivity. The $N_2O$ inventory for upland farming in temperate region like Korea revealed that $N_2O$ flux due to unit amount of N-fertilizer application for Chinese cabbage in fall (autumn) season was comparatively higher than that of summer vegetables like red pepper. Therefore, the judicious N fertilization following recommended dose is required to suppress $N_2O$ emission with high vegetable productivity in upland soils.

  • This experiments were carried out to investigate the growth responses of spinach to temperature controlling by shading treatments at different times during the summer, and the effects of environmental parameters on the growth and yield were evaluated. The fourth cultivation was showed maximum temperature at air temperature of 33.1$^{\circ}C$ and soil temperature of 28.6$^{\circ}C$, followed by third, second, fifth and first cultivation. Among the tested temperature decreasing by shading, shading with silver - coated PE film strips was the most effective in lowering greenhouse air temperatures by showing 1.1$^{\circ}C$ decrease as compared to the outside air temperature and 3.1$^{\circ}C$ decrease as compared to the air temperatures inside the non-shaded PE house and 2.3$^{\circ}C$ decrease as compared to the air temperaturese shading with black- coated PE film strips, the soil temperature was showing 2$^{\circ}C$ decrease in both shading treatments than non-shaded PE and outdoor. In first cultivation, difficult cultivated as compared to others period owing to bolting of spinach. This first period was cultivated used two domestic cultivars and six imported cultivars, significantly better growth and higher yield of spinach were recorded in glory, manchuparuk and sunlighr cultivars. The effectiveness of shading on spinach, as expressed by the crop yield increase, was the highest in the planting from July 1 to August 24.

  • This experiment was carried out to compare growth and fruit setting characteristics in ten winter-planted paprika (Capsicim annuum L.) cultivars. Five red line paprika cultivars ('Maduro', 'Maranello', 'Nagano', 'Sirocco' and 'Special') and five yellow line paprika cultivars ('Coletti', 'Sven', 'Thialf', 'Volante' and 'Zagato') were used for this study. The experiment was performed for 42 weeks, from winter of 2013 to autumn of 2014. Based on the growth stages of paprika, growth characteristics were investigated six times, and each investigation was categorized from group 1 through group 6. The relative internode ratio showed a normal range at the early growth stage, but tended to gradually decline as growth progressed. This trend was greater in red line paprika than in yellow line paprika. Among the cultivars used for this experiment, 'Special' and 'Zagato' showed growth inhibition, whereas 'Maranello' and 'Volante' kept a balanced growth during summer cultivation. The fruit set percentage in yellow paprika was 10.8% higher than in red paprika, while the number of branches in yellow paprika was 4.1% less than in red paprika. When measured after the full fruiting age, from June to July, the number of fruit set in group 4 was much lower in 'Sirocco' and 'Coletti' than in any of the other cultivars, indicating that they were more sensitive to the growth environment during the rainy season. These findings suggest that 'Maranello', 'Nagano', 'Sven', 'Thialf', and 'Volante' could be effectively used for summer cultivation in a high-plastic-film greenhouse, and 'Maranello', 'Special', 'Volante', and 'Zagato' could be good candidates for a low-plastic-film greenhouse.
