Research on the production of onion in labor-saving and safe manner

Research on stable production and supply of standardized export products.

Research on how well the mechanization can be applied in cultivating crops.

Research on how environmentally-friendly agricultural technology can be developed.

Performance

1.Developing the technology to produce onion stably.

• Raising species: Selecting good species: 24 and checking the productivity :3
• Selecting proper covering material in case of plug seed culture: reducing labor by 88% by using net.
• Inhibiting Rhizoctonia disease with chemicals: With Pensicuron, the disease can be eliminated by 85 %.
• Research on the proper volume in nitrogen fertilizer with Shallot: Increased by 15% to 30kg/10a.
• Registering patent for the manufacturing method of onion fermented liquor: alcohol content: 12.8%.

  Main fermenting processes

  Selection of good material → Cleaning → Cutting and squashing → Extraction of juice → Addition of sugar (adjusting it to 25%) → Sterilization → Inoculation of 5% of fermenting liquid → Fermenting (25℃ , 9-13 days) → Onion liquor.

  Characteristics and effects

  It is good for adult disease such as prevention of hypertension, cure of diabetes and heart disease, and control of weight, etc.

2.Developing an automatic onion transplanting machine and seedbeds

• Developed the automatic onion transplanting machine equipped on sulky management machine which was registered as patent.
  - It reduced labor from 50.2 hours/10a to 2.5 hours/10a.
• Developing the device to fix the automatic onion transplanting machine to cultivator.
  - Insert it into seedbed → Lift the seedling → Transport and divide → Transplant and suppress → Discharge the seedbed.
• Developing the seedbed tray proper to the automatic onion transplanting machine (registered as new design)
  - Developed products: circular synthetic resin products with 348 holes and rectangular products.
• Expected effects from tray seedbed.
  - Reduced space for tray seedbed: from 40-50 m2/10a to 30 m2 /10a.
  - Reduced seeds consumption required: from 8 ㎗/10a to 4 ㎗ /10a.

Future plan

• Developing good onion species: selecting good species: 36, verifying the productivity : 5
• Research on plug seedbed technology for mechanized transplanting: selecting proper coating inhibitor, coating material, and coagulants
• Establishing the culture technology of spring onion at flat field: 4 projects including the selection of proper species.
• Research on raising good shallot species and how to harvest more crops: Selecting species, and productions by regions.
