In the process of planting crops, it is greatly affected by the growing environment. The effects of weather, watering, fertilization, and pesticide s are important for the growth of crops and the final harvest. In order to cope with the bad weather, agricultural greenhouses have emerged. In order to make watering, fertilization and pesticide s more convenient and effective, water and fertilizer integrated control equipment has emerged. But so far, there have been no equipment facilities that can combine several, so that it is impossible to fundamentally solve the impact of weather and water and fertilizer on crops. In order to further promote the development of modern agriculture and fundamentally solve the problem of crop growth, this paper puts forward the automatic control equipment of dynamic water, fertilizer and pesticide, which adjusts the dynamic water, fertilizer and pesticide according to the different dynamic changes of weather, soil properties and crop varieties.
