An irrigation system and method based on the spectral response of citrus canopy

Abstract

The invention discloses an irrigation system and method based on the spectral response of the citrus canopy. First, the canopy spectral image of the citrus orchard and the growth environment information of the citrus are obtained, and transmitted to a cloud server through GPRS technology. The cloud server processes the spectral data and then inputs the Into the pre-trained water stress index prediction model, the water stress status map of the entire citrus orchard is obtained. The upper computer obtains the water stress status of the entire park, extracts the area that needs to be irrigated, and then calculates the irrigation volume of each area through the fuzzy controller, and then sends it to each irrigation control node through the wireless sensor network to irrigate the entire park , Realize the monitoring and irrigation of the water in the citrus orchard, and the water resources have been fully utilized.

Description

An irrigation system and method based on the spectral response of citrus canopy technical field The present invention relates to the technical field of agricultural irrigation management and control, more specifically to a kind of spectral response based on citrus canopy. appropriate irrigation systems and methods. Background technique Along with the gradual shortage of water resources, coupled with the extravagance and waste of irrigation water, the situation of agriculture is more and more caused by drought. Seriously, the water resources for agricultural irrigation are becoming increasingly scarce. Water deficit is one of the main factors leading to the severe reduction of citrus yield and quality. Using traditional manual monitoring will lead to the discovery of crop water shortage when the crop is already under severe stress and cannot make appropriate measures. Irrigation decision-making, resulting in a lot of waste of water resources; and some methods that ca...

Problems solved by technology

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
