ISHS Acta Horticulturae 76: Symposium on More Profitable Use of Energy in Protected Cultivation
A THEORY FOR OPTIMALIZATION OF PRIMARY PRODUCTION IN PROTECTED CULTIVATION: - I. INFLUENCE OF AERIAL ENVIRONMENT UPON PRIMARY PLANT PRODUCTION |
| Author: | H.Z. Enoch |
| Abstract:
An analysis of plant production in greenhouses is presented which emphasizes the energy costs and compares protected cultivation with other agricultural systems. An estimate is given for the energy expenditure needed to provide light, carbon dioxide and heat in the greenhouse. A model of net photosynthesis rate as a function of light, carbon dioxide and leaf temperature is used to compare the CO2 uptake rate of a C3-plant (spray carnation) inside and outside the greenhouse at selected environmental conditions. | |
