1. Control illumination: Many plants cannot grow without sufficient illumination. For yam, it is necessary to provide illumination, and the illumination time should not be too long.Long light time is conducive to the growth of branches and leaves, but not conducive to the development of rhizomes.Generally, strong light should be used, but the time should not be too long, so as to accelerate the accumulation of nutrients and improve its quality.
2. Proper fertilization: If the yam wants to grow well, it must provide a lot of nutrients, so it should be fertilized well.Fertilization is mainly based on base fertilizer, usually organic fertilizer or decomposed farm manure, which can provide nutrients continuously.In the growth period, appropriate topdressing is needed, nitrogen fertilizer is the main fertilizer in the early stage to promote the development of branches and leaves, and then compound fertilizer should be applied in order to make roots grow.
3. Build a frame to attract vines: Yam is a vine plant. If it is not managed, it is easy to block each other's growth, resulting in poor ventilation and lighting of the leaves, affecting its development.Usually, it is necessary to set up a bracket on it so that its vines can grow along the bracket, so as to ensure good air circulation and better sunshine.The height of the bracket is 1.8-2.4 meters, and the minimum height shall not be less than 1.6 meters.
