METHOD FOR WASTEWATER MEASUREMENT AND CONTROL OF WATERWORK WHEN GROWING PLANTS IN SUBSTRATE-SAVING PROCEDURES

摘要

Methods for drainage and irrigation control in the cultivation of plants in substrate-sparing processes serve the optimal supply of the plants with water and nutrients. For this purpose, the drain water from a substrate channel in a measuring system, which is designed as a tilting bowl and is coupled via a balance bar with a dip flag of a slot initiator or similar evaluation systems, quantitatively recorded and used via a subsequent evaluation for controlling one or more Bewaesserungskreisen. The method allows a control on the principle of minimum excess and can without the expense of an additional detection of the water requirement of the plants influencing influencing factors, such as radiation, temperature u. a. be used in any control system for plant watering when growing in substrate-saving processes.
