METHOD AND APPARATUS FOR THE AUTOMATIC REGULATION OF THE IRRIGATION OF PLANTS

摘要

The invention relates to a method for the automatic irrigation of plants, wherein the temporal progression of soil moisture is determined from measured soil moisture values, and said progression is used for the calculation of an optimized irrigation time duration, such that both water excess in the soil and soil drying are avoided as much as possible. Preferably, the time duration of irrigation is constantly evaluated and optimized using comparisons of measured values with prespecified moisture- and dryness threshold values (GWmoist, GWdry), and automatically adjusted to changing environmental conditions and/or plant requirements.

主权项

1. A method for automatically controlling an irrigation duration, the method comprising
calculating an irrigation duration by the aid of evaluation electronics and an application specific characteristic K; obtaining a soil moisture value by measuring soil moisture using a sensor after a soil irrigation operation for the calculated irrigation duration has been conducted; comparing the obtained soil moisture value with a target upper moisture limit value using the evaluation electronics and, in the event that the obtained soil moisture value deviates from the target upper moisture limit value, applying a correction to the application specific characteristic K to thereby alter an irrigation duration for a subsequent soil irrigation operation.
