| Abstract:
In order to use and reach flexibility in a modern and complex control system, growers need qualified knowledge about handling the system as well as qualified knowledge about plant production and plant material. So the technical development and construction need to go hand in hand with biological claims and requirement to produce satisfactory plants and plant material at minimal labour and energy inputs and with economical gain. In view of this we have started studies on the effects of energy-saving constructions on the plant material and the effects of different environmental factors and changes of these factors. In other words studies of the optimal and reasonable possibilities of dynamic climate control in relation to the environmental conditions to plant growth. The aim is to receive information about environmental effects on plant growth capacities. Tolerances to changes and fluctuations in the environmental conditions as well as adaptive abilities. An additional important factor for dynamic cultivation schemes is the time factor for effects on growth and development of the environmental conditions. If simple dynamic controlled plant environmental conditions are useful in greenhouse production, computers are valuable means. The project and the studies can be divided in different systems, however interacting more or less. | |
