| Outline of Final Research Achievements |
Silicic acid is an important nutrient for improving yield and reducing stress of rice, and continuous supply is important, but application of silicic acid materials is omitted due to soaring raw material prices. Reeds that live in wetlands absorb silicic acid like rice and protect the wetlands by cutting them regularly. Therefore, in order to effectively utilize reeds to supply silicic acid to rice while maintaining the environment, we examined the materialization of reeds, the time of harvesting, resource evaluation, and rice application technology. The results showed that reeds in the Mogami River basin in the Shonai region of Yamagata Prefecture had chromosome multiplicity of 8 and 10, and that the higher the soil nutrient content, the higher the growth rate, and that reeds mowed after maturity could be made into material while protecting the wetland. When the material was applied to seedlings and paddy fields, growth and silicic acid absorption of rice plant were improved.
