Irrigation system and method based on citrus canopy spectral response

Abstract

The invention discloses an irrigation system and method based on citrus canopy spectral response. The method comprises the steps of firstly obtaining a citrus orchard canopy spectral image and citrus growth environment information, transmitting to a cloud server through a GPRS technology, processing the spectral data through the cloud server, and inputting the processed spectral data into a pre-trained water stress index prediction model; obtaining a water stress condition diagram of the whole citrus orchard. An upper computer obtains the water stress condition of the whole orchard, extracts areas needing irrigation, calculates the irrigation amount of each area through a fuzzy controller, sends the irrigation amount to each irrigation control node through a wireless sensor network to irrigate the whole orchard, and achieves the monitoring and irrigation of the water of the citrus orchard. Water resources are fully utilized.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation management and control, in particular to an irrigation system and method based on the spectral response of citrus canopy. Background technique [0002] With the gradual shortage of water resources and the extravagance and waste of irrigation water, the situation of agricultural disasters caused by drought has become more and more serious, and the water resources for agricultural irrigation have become increasingly tense. Water shortage is one of the main factors leading to serious reduction in yield and quality of citrus. Traditional manual monitoring will lead to serious stress when crops are found to be short of water, and cannot make appropriate irrigation decisions, resulting in a large waste of water resources. ; and some methods that can accurately measure the moisture status of crops are inconvenient to operate and cannot remotely irrigate crops. At present, the wireless sen...

Water shortage is one of the main factors leading to serious reduction in yield and quality of citrus. Traditional manual monitoring will lead to serious stress when crops are found to be short of water, and cannot make appropriate irrigation decisions, resulting in a large waste of water resources. ; and some methods that can accurately measure the moisture status of crops are inconvenient to operate and cannot be used for remote irrigation of crops. At present, the wireless sensor network used in some areas to monitor the moisture status of crops is only suitable for small farmland
