The invention relates to the technical field of indoor planting, in particular to a method for planting crops applied to the industry. The method comprises the steps of providing an environment control system with temperature, humidity and illuminance of a crop capable of being changed; observing the affect of illuminance, temperature and humidity on growth of the crop, and obtaining three environment parameter curves indicating the change of the optimal illuminance, temperature and humidity of the crop along with time and the growth curve of the crop indicating the change of growth of the crop along with time; establishing a reference growth function of the crop according to the three environment parameter curves and the growth curve. By providing the environment control system, obtaining the optimal environment parameter curves of the crop and establishing the reference growth function of the crop, industrial production of the crop is controlled so as to obtain the optimal growth mode. Furthermore, the growth speed of the crop can be controlled by changing environment parameters.
