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

Abstract

The invention discloses a crop water-saving irrigation decision-making method and a measurement and control system based on multi-source information fusion, which belong to the field of crop irrigation. The knowledge base and crop evapotranspiration prediction information are fused with multiple information, and the optimal irrigation results are obtained and sent to the irrigation control system to regulate the start and stop operation of water pumps and solenoid valves, so as to realize water-saving and precise irrigation of crops. On the one hand, the measurement and control system is used to collect farmland moisture information, and on the other hand, it receives optimal irrigation results to achieve precise irrigation. The multi-source information fusion method of the present invention not only satisfies the water requirement of crop growth, but also achieves the goal of water-saving precision irrigation.

Description

technical field 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 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 urgent. In rec...
