WIPO Patent Application WO/2019/205612
Kind Code:
A1
Abstract:
Disclosed is an automatic irrigation control method, comprising: starting intermittent irrigation, in which irrigation is started when the radiation cumulant is larger than or equal to a preset radiation threshold value, and after each irrigation, the radiation cumulant of irrigation is controlled to return to zero and the radiation cumulant of irrigation is recalculated; detecting whether a first characteristic value is greater than or equal to the preset threshold value, and if yes, stopping the intermittent irrigation, wherein the first characteristic value is used for representing the extent to which the irrigation liquid is not absorbed by plants; calculating a difference value between the stopping time of the intermittent irrigation and sunset time, and if the difference value is larger than a first preset duration, restarting irrigation once before the sunset time. By means of the method, reasonable irrigation of crops is realized,, which ensures that the irrigation amount satisfies the growth requirements of the plants; meanwhile, resource waste caused by excessive irrigation is avoided. Further disclosed are a server capable of executing the method and a computer readable storage medium.
