First, the election. Any place where a bud is raised or transplanted must be a land that has not been planted for more than 3 years. Second, buds. 1. Selection of potatoes: The original or original species harvested in the previous year is carefully selected, and 100 grams of uniform and uniform potato pieces are selected to remove the deformed and deformed potato pieces. 2. Pregermination: The selected potato pieces will be spread on the ground in the nylon net shed, and the germination seeds will be dried for 10-15 days. The surface of the seed potatoes will become soft and the top buds will grow to the bean size when the planting potato shoots. 3. Breeding Bud Bed: The bed is 1 meter wide, 2.5 meters long, and 0.3 meters deep. The fresh donkey horse manure is used to filter into small pieces and spread into the bowl. The thickness is up to 0.2 meters, and the water is poured and watered. To the extent that the foot is applied to the surface of the fertilizer, it is advisable to squeeze the water around the foot. Timely plus small plastic shed, plastic seal with plastic cover, in the greenhouse greenhouse 25-35 degrees Celsius let it fully decomposed a week is appropriate. 4, planting potatoes: first spread the surface of the bed 3 cm thick fluvo-aquic soil, and then put the seed germination selected and put into the bed, tuber umbilical downward, top up, tilted from north to south, The distance between the potato and the potato is about 4 centimeters, and then 3 centimeters are spread on the surface of the seed potato to scrape the surface. If the surface layer is dry, spray it properly to moisten the topsoil and then cover the plastic. The film is incubated and incubated. On May 23, planting potato shoots were planted. The first axillary buds were carried out on June 10, the first germination period was 18 days, and the second germination period was 12 days. Third, transplanting. 1. Do the trick: In the nylon net room, make a smooth, wide 1 meter, apply enough base fertilizer, and apply 3,000 kg of high quality manure fertilizer and 40 kg of ammonium nitrate per acre. 2. Transplanting of axillary buds: When the buds of seed germinating buds grow to 3-4.5 cm and they are stout, with a root length of about 9 cm and a large number of fibrous roots, they can be transplanted.
