Abstract:
In this paper some conclusions are given which resulted from a working-party on "Greenhouse design and cladding materials". During this meeting many excellent papers and posters were produced.
They provided the participants with much valuable information that formed the basis for the discussion periods.
Ample time was available for the discussions and thus different results and opinions could be fully evaluated.
In several cases this approach led to new hypotheses as well as serving to stimulate further research work.
The papers as published in this Acta Horticulturae nr. , demonstrate the strong interrelationship which exists between
- local conditions
- greenhouse design
- cladding materials
- insulating measures.
However, it is evident that more information is needed especially on the effects of greenhouse design and cladding materials on the greenhouse climate and cropping results.
If this is to be realized a generally accepted standardization of measuring methods and devices is necessary to make the results transferable.
The discussions clearly demonstrated this need.
In this connection reference has to be made of the Acta Horticulturae nr. 90 (December 1982) "Harmonisation of parameters in protected cultivation". This publication gives a good basis for further agreements on standardization.
Throughout this meeting it was obvious that greenhouse design has to meet various requirements because local climate conditions as well as the aims of the users may differ considerably.
Herefore, it is possible that a range of appropriate greenhouse designs can be identified which are all well adapted to a specific site.
