Automated irrigation control method

Abstract

The embodiment of the invention relates to the technical field of agriculture, and discloses an automated irrigation control method. The automated irrigation control method comprises the steps that within a first period, irrigation is started once at first preset time; within a second period, when the radiation accumulation amount equals to a first radiation threshold, irrigation is started once,and if irrigation is not started within a first preset duration, irrigation is started once at the first preset duration; within a third period, on sunny days, when the radiation accumulation amount equals to a second radiation threshold, irrigation is started, and the radiation accumulation amount is re-accumulated; before sunset, irrigation is ended; on cloudy days, when the radiation accumulation amount equals to a third radiation threshold, irrigation is started, if irrigation is not started within a second preset duration, irrigation is started at the second preset duration, after every-time irrigation, the radiation accumulation amount is re-accumulated, and time is reckoned; before sunset, irrigation is ended. The provided automated irrigation control method achieves reasonable irrigation of crops and satisfies different irrigation demands of the crops in different weather conditions.

Description

technical field [0001] The embodiment of the present invention relates to the field of agricultural technology, in particular to an automatic irrigation control method. Background technique [0002] Greenhouses, also known as greenhouses, can transmit light and keep warm (or warm) for growing crops. In seasons that are not suitable for crop growth, it can provide a greenhouse growth period and increase production. It is mostly used for cultivation or seedling cultivation of temperature-loving vegetables, flowers, forest trees and other crops in low temperature seasons. Since the growth of crops is inseparable from the water supply, irrigation devices are an important part of the greenhouse. In order to facilitate irrigation and reduce manpower, an automatic irrigation device is installed in the greenhouse in the prior art, and the automatic irrigation device can intermittently irrigate greenhouse crops at a specified time according to a preset irrigation program.

AI Technical Summary

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the prior art: in the automatic irrigation process of the prior art, due to different weather conditions, the water supply required by the crops is different, and the use of a single control strategy cannot meet the different irrigation needs of the crops under different weather conditions
