1. Automation of Forced Germinator for Production of Some Sprout Vegetables
This study aimed at development of a device optimizing the growth conditions, such as immersion temperature and time, aeration and so on. The findings of this study showed that the effect of immersion temperature on germination ratio was good under given temperatures. The germination ratio with aeration was 0.3∼7.3% higher than the one without aeration. In addition, the optimal time of aeration was achieved between 9 and 12 hours, but the continuous aeration time also showed the good growth of sprout vegetable in this study.
2. Improvement of seeder for Production of Some Sprout Vegetables
Published materials was ellipse sphere type radish seed, and its major axis diameter, minor axis diameter, thickness, and weight of thousand seeds were 4.23mm, 2.49mm, 2.46mm, and 23.74g, respectively. The results of sowing rate test according to opening adjustment rate and roller speed were as follows: the difference of sowing rate were showed as 83.3~164(60Hz), 84.1~162.4(50Hz), and, 83.5~159.8(40Hz) when opening area for sowing were 17.7㎠, 23.6㎠, and, 28.5㎠, respectively. But sowing roller speed did not showed significant difference. The smaller sowing roller diameter, and the faster rolling speed sowed more uniformly.
3. Development of cultivation system for the production of sprout vegetables
The light intensity of cultivation system was higher at the middle of bottom, and uniformly in the radial light intensity weakened. To solve this problem, we have to control light interval according to the light intensity. As growth rate according light intensity, the higher light intensity, the faster growth rate under fluorescent lamp and there was no difference of growth rate under LED light. Growth rate was faster in all varieties by bottom watering than over spraying. This considered that due to the bottom watering method supplied more moisture to the root by water contact directly. Growth rate was slightly faster under fluorescent lamp than LED light within significant differences. This showed that fluorescent lamp which had multi-wavelength was more advantageous than LED light which had single wavelength in sprout vegetable production.
4. Development of harvest system of sprout vegetables
This study was accomplished to develop harvest system of sprout vegetables like broccoli, canola, pea, buckwheat and so on. Because of eco-friendly agriculture, sprout vegetable farmers usually use nursery bed soil with seedling box. And harvest sprout vegetables by hand with hand held harvester from slantly stand seedling box against working bench. Developed harvester was designed for saving harvest labor and time by continuous operation with seedling tray contained sprout vegetables and rooted nursery bed soil. Sprout vegetable harvester was composed slope bench, metal chain belt, cutting blade, controller, etc. Slope bench could control the angle of seedling box not to spill nursery bed soil into sprout harvest box. Chain belt could move to cutting blade seedling box continuously by push bar connected with metal chain. Linear velocity range of chain belt was measured from 4 m/min to 10 m/minute, and supply time range of seedling box was from 50 sec/10box to 102 sec/10box. Cutting blade could harvest sproutvegetables by alternating motion with cam connected electric DC motor decelerated 1/60 ratio. RPM range of cutting blade was from 575 RPM to 1075 RPM. Harvest time required of sprout vegetable harvester and manual labor harvest were 190 sec/10box and 60 sec/10box, respectively. As ad result, developed sprout vegetable harvester could save labor time required by 68% compared with using hand held harvester.
