Crop irrigation method, device and system and readable storage medium

Abstract

The invention discloses a crop irrigation method, device and system and a readable storage medium, and belongs to the technical field of agriculture, and the method comprises the steps: S1, collectingcrop environment information from a vegetation field of a crop, wherein the crop environment information comprises temperature data, humidity data, long-wave net radiation data and short-wave net radiation data; s2, processing the crop environment information by using a maximum entropy increase model to obtain a potential evapotranspiration amount and an actual evapotranspiration amount of the crop; S3, calculating a crop coefficient Kc corresponding to the crop by utilizing the potential evapotranspiration and the actual evapotranspiration, wherein the crop coefficient Kc is used for representing the condition that the crop is subjected to water stress; and S4, generating an irrigation strategy based on the crop coefficient Kc corresponding to the crop so as to irrigate the crop. Crops are irrigated in a targeted mode, the irrigation reliability is good, the irrigation accuracy is high, and the problem that the crops are not fully irrigated or excessively irrigated can be effectivelysolved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and more specifically relates to a crop irrigation method, device, system and readable storage medium. Background technique [0002] Crops, also known as cultivated plants, refer to all plants cultivated for direct or indirect human needs.
