Abstract
In late years a study about the useful material production by the genetic recombination plant is prosperous in various quarters, and some development about the cultivation facility are performed, too. There is a soy bean in the one of the plant species to cultivate in such an facility. There is extremely much protein content in the crops, and the soy bean is regarded as rose color as a host plant of the useful material production. In this study, I give environment condition suitable for the growth of the recombination soy bean and plan the construction of the closedown type plant production institution to cultivate uniformly and report it about the result that examined the environment condition in CFD before construction.
