The first is to popularize high-yield, high-quality varieties suitable for the local area and to make appropriate combinations. The second is germination sowing. Breaking the dormant period to germinate the autumnal pods is the key to improving yields. Practice has shown that germination can increase the rate of emergence by 20-30%, early emergence of 7-10 days, and neat and robust. Specific approach: cut the yam into small pieces (each one guarantees 1-3 buds), then use cold water to wash the juice, and cool dry germination. The number of layers of germination is generally no more than 2 layers, a layer of sand and a layer of lumps, and then the pods are germinated. In the process of operation should adhere to the "five should five not appropriate", that is, should not be small, large and small layers should not be more, soil (sand) should not be wet, dry time should not be short, buds should not be short long. The third is to focus on standardized planting. The main planting methods are as follows: First, the relay is used for rice transplanting. After the rice is harvested, the soil is deep-turned, the base fertilizer is re-applied, and the rope is drawn. The transplanting is carried out according to the specifications of 17 cm (24+50) cm or 17 cm (30+54) cm. Two rows of single rapeseed were planted in 50- and 54-cm columns, and two-way faulty potato was planted in rows of 24 and 30 cm, which promoted the harvest of rape and potato. The second is net work. The use of fields such as Tianshao and Chaotai for planting autumn yam is suitable for 17cm20cm. The fourth is scientific fertilization. Generally, 1500 kilograms of organic manure, 30-50 kilograms of phosphate fertilizer, 150-200 kilograms of plant ash, and 5-10 kilograms of bio-potassium are mixed and used for planting. The fifth is mastery. When the young plants grow 60-70% in autumn, they use 2.5-3 kg of urea, 1600-2000 kg of water and fertilizer, and when they grow to 30-40 cm, they use 500 kg of plant ash and 40-50 kg of human and livestock urine. Mix well and apply for soil. At the same time pay attention to the prevention and control of pests and diseases in various periods.
