Description
Summary:Aiming at the problems of high control cost and high water consumption in the current commercial greenhouse automatic irrigation system, this paper presents an algorithm of crop water demand model based on nonlinear identification of water, fertilizer and medicine integrated water-saving irrigation, and establishes a model of crop water demand model based on nonlinear identification of water, fertilizer and medicine integrated water-saving irrigation, which can ensure the normal output of crops and save water In order to improve the estimation efficiency of crop water demand model, based on the empirical irrigation amount, matlab simulation is used. Matlab simulation results show that the irrigation effect of water fertilizer is good and the nonlinear identification ability is strong. The results of the greenhouse tests in Tianshui City and Qingyang City of Gansu Province show that the control system reduces the water consumption by 30% and allocates water resources reasonably and effectively, which greatly reduces the waste of water resources.
