Method for culturing and transplanting seedling of cassava

The invention discloses a method for culturing and transplanting a seedling of cassava, which belongs to the technical field of plant cultivation. In the method, the seedling is cultured at the end of a dry season and at the beginning of a rainy season, wherein the furrow height of the cultured seedling is 15 to 20cm and the width of a furrow surface is 8 to 10cm; a seedling culturing material adopts a stem section cuttage propagation method; a stem stick under a branch of the cassava is cut off to form a seed stem, wherein the length of the seed stem is 15 to 20cm and the thickness of the seed stem is 1 to 3cm; a root dipping agent is prepared by mixing 0.5 to 1 kilogram of calcined lime, 0.5 to 1 kilogram of rooting powder and 10 to 20 kilograms of water before cuttage; after dipped into the root dipping agent, the seed stem is inserted into the furrow surface, wherein the distance between every two seed stems is 20 to 25cm; and thoroughly decomposed clear dung water is used for irrigation for one time after 3 to 5 days of the cuttage, the seedling with the height of 8 to 15cm is transplanted. The method has the advantages that average survival rate is up to 92 percent, planting survival rate is 18 percent higher than that of plants by the conventional cultivation method, 300 strips of sprouts are saved in each square hectometer, 20 days of labor force is saved in each square hectometer, operation is simple and convenient and the method is easy to grasp.
