Efficient cultivation method for increasing yield and starch content of canna edulis

The invention discloses an efficient cultivation method for increasing the yield and starch content of canna edulis. The method comprises steps of land selection, soil preparation, sowing, field management, pest disease and weed control, maturation, harvest, and seed reservation. The method comprises following operation steps: (1) land selection and soil preparation; (2) sowing including variety selection, sowing time selection, potato seed processing, base fertilizer application and planting mode selection; (3) filed management including seedling stage management, intertillage weeding and hilling, top application of fertilizer, water management and florescence management; (4) disease and pest control including disease control and pest control; (5) maturation and harvest; and (6) seed reservation. By employing the method, the canna edulis is high in yield and starch content, and problems that the canna edulis is low in mu yield and starch content are effectively solved. Through the interplanting of canna edulis and soybeans, the growth of weeds can be effectively controlled, soil is loosened, nitrogen is fixed through soybean rhizobium, the application amount of fertilizer can be reduced, green leaves and stems of the harvested soybeans can be returned to the field, the soil productivity can be increased, and finally the income of farmers can be increased.
