Abstract
Provided are a control method and system for water and fertilizer under drip irrigation. In the method, the crop type, soil type, fertilizer type, water-fertilizer irrigation amount and other factors are coupled with the drip irrigation tape parameters in the drip irrigation system, and matching calculation is performed to obtain the fertilization duration. In addition, deduction and calculation are performed according to the solubility of the fertilizer, the fertilization amount, the rotation irrigation area and the fertilization duration determined by the self-allocation system, and the characteristic that the maximum fertilizer absorption amount is reached when the outlet of the Venturi fertilizer applicator is at −9 m is combined, so as to determine key components of the fertilizing machine in the drip irrigation system.
