초록 ▼

A process and device for managing irrigation of plants or crops using crop canopy temperate measurements by use of a specific time threshold. In this process, the canopy temperature of the target plant is repeatedly measured with an infrared thermometer. After each measurement, the canopy temperature is compared with a predetermined threshold canopy temperature, above which temperature the plant is thermally stressed. If the measured canopy temperature is less than or equal to the threshold canopy temperature, or if the existing humidity is restrictive to plant cooling, then irrigation is not indicated and the canopy temperature measurement is repeated at its designated time. However, if both the measured canopy temperature is greater than the threshold temperature, and the humidity is not restrictive to plant cooling, then an increment of time is added to a time register. The accumulated time in the time register is then compared to the time threshold, a predetermined constant defined as about the mean of the length of time per day that the canopy temperature for the plant, in a well-watered and non-stressed condition, exceeded the threshold canopy temperature in the target geographical area. As long as the accumulated time is substantially less than the time threshold, irrigation is either unnecessary or ineffective to achieve transpirational cooling, and the process is again repeated with measurement of the canopy temperature. However, once the accumulated time exceeds or is approximately equal to the time threshold, transpirational cooling is indicated and an irrigation signal is generated.

A method for use in managing the irrigation of plants comprising: a) measuring the canopy temperature of a target plant at a regular interval of time, ti, using an infrared thermometer; b) measuring the atmospheric humidity in the vicinity of said plant; c) comparing said canopy temperature with a threshold canopy temperature, said threshold canopy temperature for said plant being approximately that canopy temperature which is effective for optimal plant metabolism, and determining if said humidity is restrictive to plant cooling; 1) returning to said step (a) if either: (i) the measured canopy temperature is less than or equal to said threshold canopy temperature, or (ii) said humidity is restrictive to plant cooling; 2) adding an increment of time equal to ti to a time register to provide an accumulated time if both the measured canopy temperature is greater than said threshold canopy temperature, and said humidity is not restrictive to plant cooling; d) comparing the accumulated time in said time register to a time threshold, wherein said time threshold is determined as about the mean of the length of time per day that the canopy temperature for said plant in a well-watered and non-stressed condition exceeded said threshold canopy temperature; 1) if said accumulated value is greater than or approximately equal to said time threshold, then generating and displaying an irrigation signal, or automatically initiating irrigation, or both; 2) returning to said step (a), if said accumulated value is not greater than nor approximately equal to said time threshold.
