<P>PROBLEM TO BE SOLVED: To provide a greenhouse cultivation system with an easy structure, suppressing aging of implanted stumps a little, and securing a maximum yield through long term harvesting. <P>SOLUTION: This greenhouse cultivation system includes a solar radiation introducing part (1) for receiving solar radiation light for implanted stumps, and a light amount regulating mechanism regulating the increase and decrease of the amount of light received for the implanted stumps. The light amount regulating mechanism comprises a light supplement lump (3), and performs light supplement regulation control so as to compensate light amount insufficiency according to sunshine, by obeying a standard light amount (C2) set in a diurnal pattern continuously changing in a range in which the amount of light received in a daytime time zone is brought to the maximum level in a range allowing the avoidance of sunshine stress, and the minimum amount of light received in a night time zone is brought to zero. <P>COPYRIGHT: (C)2011,JPO&INPIT |
