The cotton has long growth period, large water and fertilizer requirements, and the water and fertilizer saving technology must be vigorously developed to improve the competitiveness of the Xinjiang cotton industry. Drip irrigation under the film is used as a Xinjiang cotton planting mode in a large area, and automatic control is basically realized; however, in the aspect of fertilizer application, due to the problems of unstable external water pressure, low reliability of fertilizer application equipment and the like, the fertilizer is still applied mainly by manual experience. Therefore, it is necessary to develop a precise water and fertilizer integrated control system suitable for Xinjiang cotton fields.
The invention relates to a water and fertilizer integrated precise fertilization control system, which aims to realize precise fertilization of cotton fields, improve the yield of cotton and accelerate the healthy, rapid and stable development of Xinjiang and war group cotton industries.
