Method and system for optimizing harvesting decision of citrus fruits

Abstract

The invention provides a method and system for optimizing a harvesting decision of citrus fruits. The method comprises the steps that a fruit ripeness prediction model is established by using historical accumulated temperatures and fruit ripeness dynamic change as indexes, dynamic prediction of fruit ripeness in a citrus orchard based on real-time accumulated temperatures is achieved, and the suitable ripeness standards of fruits for different purposes (processing or fresh eating) are determined; on the basis of establishing the fruit ripeness prediction module of the citrus orchard, a suitable harvesting time prediction model based on the different-purpose fruit harvesting standards with the accumulated temperatures over the year and the real-time accumulated temperature in the current year mutually corrected is established, and the precision and the reliability of the ripeness time prediction are improved. Through a citrus orchard fruit suitable harvesting time prediction technology and a yield non-destructive detection technology, an intelligent citrus fruit optimization harvesting decision system is developed, harvesting of the citrus fruits in the citrus orchard in batches is better achieved, the fruit supply period is prolonged, coordinate supply relation of an enterprise and base users can be achieved, and a support is provided for coordinate connection of the citrus fruits and enterprise processing and fresh fruit marketing progress.

Description

technical field [0001] The invention belongs to the technical field of fruit intelligent harvesting, and in particular relates to a method and system for high-quality harvesting decision-making of citrus fruits. Background technique [0002] The construction of my country's citrus industrialization base started late, the processing and marketing cycle is difficult to improve, and the utilization rate of processing equipment and marketing personnel is low. Although some studies have been carried out on winter fruit preservation technology in the main citrus producing areas of China, through scientific treatment, the fruit drop rate of varieties such as overwintering summer oranges and golden oranges in the experimental garden has been controlled at 5% to 10%, and the maturity period of varieties has been adjusted to 5%. ~June, but the blindness and randomness of citrus harvesting in China are still very large. Most farmers judge the maturity period based on experience, or har...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method and system for high-quality harvesting decision-making of citrus fruits, aiming to solve the blindness and randomness of citrus harvesting in my country, which leads to high concentration of raw material fruit time in processing plants and fresh fruit markets, and long-term supply. The problem of few and uneven quality
