And high- set cultivation equipment , construction method of the moisture-permeable waterproof sheet in a high- set cultivation equipment

摘要

PPROBLEM TO BE SOLVED: To provide an elevated cultivation device having a simple structure, facilitated in construction, excellent in workability and reduced in initial cost. PSOLUTION: The elevated cultivation device 1 is structured so as to support a cultivation tank 3 wrapping culture media 3b with nonwoven fabric 3a between two shafts 2, 2(A) set up in parallel, and fixedly plant seedlings 4 in the cultivation tank to cultivate the seedlings. The device includes: a moisture-permeable waterproof sheet 5 supported between the two shafts 2, 2(A) so as to cover the lower part and the upper part of the cultivation tank 3; an air blowing pipe 13 blowing air to the lower space 7 between the lower part of the cultivation tank and the moisture-permeable waterproof sheet; and a watering tube 10 watering the upper space 8 between the upper part of the cultivation tank and the moisture-permeable waterproof sheet. The moisture-permeable waterproof sheet is fixed to one shaft 2 at its one end, is fixed to another shaft 2A while forming a lower part space 7 so as to be apart from the lower part of the cultivation tank, and is fixed to the one shaft 2 while forming the upper space 8 so as to be apart from the upper part of the cultivation tank.
