Planting model and planting method for reducing incidence rate of perilla rust

The invention belongs to the field of plant protection, and particularly relates to a planting model and a planting method for reducing the incidence rate of perilla rust. Land is ridged, and then purple perilla is planted; the width of the ridge land is 1.4 m +/-0.05 m, and the height of the ridge land is 0.15 m +/-0.05 m; and then the purple perilla is planted on the ridge land, the planting distance of the purple perilla is 0.55 +/-0.05 m, and the line spacing is 0.95 +/-0.05 m. According to the planting method, the ventilation and light transmission performance is improved, the survival space of the purple perilla is enlarged, the root system is fully stretched, the plant shape is further enlarged, the leaf surfaces fully receive sunlight, and physiological activities such as photosynthesis and respiration of plant seedlings are enhanced. According to the method, the incidence rate and the harm degree of the perilla rust are remarkably reduced, so that the propagation and harm of mosaic diseases are reduc
