Crop water-saving irrigation decision method based on multi-source information fusion and crop water-saving irrigation measurement and control system based on multi-source information fusion

Abstract

The present invention discloses a crop water-saving irrigation decision method based on multi-source information fusion and a crop water-saving irrigation measurement and control system based on multi-source information fusion, belonging to the field of crop irrigation. The method comprises the steps of: employing multi-source information data fusion based on a support degree function to perform multi-information fusion of farmland moisture information, a crop water-requiring information knowledge base and crop evapotranspiration prediction information, and obtaining an optimal irrigation result which is transmitted to an irrigation control system to regulate and control starting / stopping operation of a water pump and a solenoid valve so as to achieve crop water-saving accurate irrigation.The measurement and control system is configured to collect farmland moisture information and receive the optimal irrigation result so as to achieve accurate irrigation. The multi-source informationfusion method meets the demands of crop growth for the moisture and achieves the purpose of water-saving accurate irrigation.

Description

technical field [0001] The invention belongs to the field of crop irrigation, and in particular relates to a crop water-saving irrigation decision-making method and a measurement and control system based on multi-source information fusion. Background technique [0002] my country is the world's largest grain producer and consumer, and the cultivation of crops requires the support of a large amount of water resources. my country's crop water consumption accounts for more than 45% of the total water consumption, and it can be called the largest water user in the whole society. However, my country's agricultural water resources are very short, and with the development of the economy, water pollution incidents occur frequently, the degree of water shortage is getting worse, the scope of water shortage is getting bigger and bigger, and the water crisis is getting closer to us. As the first in the whole society Water-saving irrigation for large water users is becoming more and more...
