Dwarf yam is generally planted in February-March, and excavation begins in September-December. 1. Soil selection: The soil with deep loose soil and sandy loam with water source should be selected. 2. Preparation and treatment of seedlings 2.1 Planting of yam medlars: At present, yam medlar is the main breeding material. When the yam dumplings are cut off, the incision is treated with stove fire ash or quicklime, and then stored in a cool, ventilated place; the yam dumplings cannot be placed in a dry place to avoid excessive loss of water and loss of germination capacity. 2.2 Planting with Chinese yam dumplings: The yam can be cut into 50- to 100-g sections, then the incision is treated with stove fire ash or quicklime, or the incision is treated with 45% carbendazim 400 times, and it is planted on the seedbed after the Spring Festival. The germination was carried out and transplanted into the field when the shoots were sprayed. . 2.3 Giving full basal fertilization and reasonable dense planting: Basal fertilizer is the key to high yield. It requires applying about 2,500 kilograms of manure per mu, 40-50 kilograms of normal calcium, and 40 kilograms of compound fertilizer. Apply planting ditch to the ground. Planting density: spacing 50 cm, plant spacing 18-20 cm, planting 4000-4500 per mu (head). 2.4 Perforated planting and perforating planting can improve the quality of yam products. The depth of drilling is about 60-70 cm, the diameter is 5-6 cm, sawdust is placed in the hole, and the yam can grow into the hole when planting. The buds are aligned with the holes, covered with earth or fine feces, poured with water, and then covered with straw or covered with a plastic film, which is conducive to water conservation and emergence. 3. Pest Control: To prevent underground pests when planting, Chlorella insecticide can be used to treat planting ditch with 2.5-3 kg of chlorine insects per acre. At present, the disease has good disease resistance and less incidence. 4, frame: frame material can be used small bamboo or other bamboo, high 1.5 meters high adult frame, will help improve the light and the use of ventilation and light, increase the output per unit area. 5 Timely Harvest: When the vines start yellowing in late August, they can be harvested and marketed. Digging the yam to be selected in the clear days, this is conducive to the storage of yam.
