Study design of water and nitrogen optimal management model based on wireless sensor and maize growth model

摘要

As the important technology of the internet of things, the development and application in agriculture of wireless sensing technology were analyzed. Crop model has more advantages in providing management decisions. The yield forecast performance of crop model is superior to that of traditional statistical model or expert system from the angles of interpretability, mechanism and accuracy. The idea of studying and constructing maize water and nitrogen optimal management model based on wireless data and crop model was put forward. Finally, the system design goals, research contents and methods, and technical route were discussed.
