養液栽培制御システムに関する研究(I) : ベット内の養液の流れ特性

The hydroculture system are now widespread among the special farmers. In these systems，the hydroculture systems having in store of water in beds have giving rise to public discussion with respect to uniformitysupply of diluted manure to culture beds.
And the objective of this studies were to obtain flow characteristies of diluted manure in the culture beds. Flow distributions of the diluted manure in beds could be able to obtain in the visual manner by using sucked white moist colors together with air by the use of a sucker. And mixing rates were influenced by the position of supply and drainage of water.
And the increase of the water flow rate was the increase of the mixing rate.
