Description

technical field [0001] The invention provides a corn monitoring agricultural internet of things system based on optical fiber sensing, which belongs to the technical field of optical fiber sensing. Background technique [0002] Maize is an important food crop and feed crop. It is also the crop with the highest total yield in the world. Its planting area and total yield are second only to rice and wheat. It has great potential for developing high-nutrition and high-biological function foods. Corn is a temperature-loving crop and requires higher temperatures throughout the growth period. The biological effective temperature of corn is 10°C, the optimum temperature for seed germination is 28-35°C, the jointing stage requires 15-27°C, the flowering stage requires 25-26°C, and the filling stage requires 20-24°C. Different corn varieties have different temperature requirements. Most of the world's corn production areas are concentrated in the range where the isotherm in July is ...

AI Technical Summary

Problems solved by technology

Due to the complex heredity of corn and the rich variety of variations, there are shortcomings in the conventional breeding process, such as too long cycle, too large coefficient of variation, and affecting the growth and development of offspring. Modern biological breeding technology not only overcomes the above-mentioned shortcomings and deficiencies, It also improves breeding speed and quality
