(l) Dicing a piece of Qiutaoqi potato to produce a “cool†character, avoiding bad seeds, ensuring that the seedlings and seedlings are strong, and selecting the size of a disease-free wound 7-10 days before sowing (single potato weight 70-80 G) Seed potatoes, cut into 3-4 pieces (20-25 pieces per 500 g) with a sharp knife and cut them along the top of the bud. Each piece has 1-2 buds, and more than 90 grams of seed chips are cut by buds. The cut surface should be flat, and the seed potato is too small (20-30 g) to be sown directly without cutting. When cutting potatoes, brown vascular bundles are found to be diseased potatoes (ring rot). Should be removed, the knife must be sterilized to prevent the spread of germs. Immediately after cutting into pieces of cold water, wash away the starch paste in order to facilitate healing of the incisions and prevent them from being rotted. Then put it in 0.5-1 ppm gibberellin solution and soak for 15-30 minutes. After removing it, spread the potato pieces to open for three or four hours and dry.

The floor should be filled with clean sand (squeezing into a group by hand and the hand loosen to a degree). The thickness is about 9 cm and the bed width is 1 meter. . When the germination buds will shoot up, closely arranged in a layer not to overlap, cover the wet sand about 7 cm thick, such as more than a piece of potato, you can press a layer of sand, a stack of two blocks, two layers, and finally close the bed On the surface, cover with straw or plastic film moisturizing, keep the bed temperature at 25-28 °C, the humidity to the topsoil but dry as well, such as bed sand dry, can use a small amount of cold water kettle wine, after 4-6 days can bud. When the shoot grows 1 centimeter, you can take out sowing. If the weather is not good, you can put it under the diffuse light for 2-3 days, so that the buds will be sturdy and then sown.
