Potato cultivation is a comprehensive and nutritious crop. The components contained in the general fresh potatoes are: starch 9% - 20%, protein 1. 5% - 2. 3%, fat 0. 1% - 1. 1%, crude fibre 0. 6% - 0. 8%. 100g nutritional content in potatoes: heat 66 ~ 113 j, calcium 11 ~ 60 mg, phosphorus 15 ~ 68 mg, iron 0. 4 ~ 4. 8 mg, sulfide 0. 3 ~ 0. 07 mg, nuclei ~ 0 03 ~ 0. 11 mg, nickric acid 0. 4 ~ 1. 1 mg. In addition, the potato truncheons contain carrots and anti-fatal acids not found in grain grains. The main factors affecting potato production are the degradation of varieties, the late planting of seeds, the late onset of high temperatures that are not conducive to the expansion of potatoes, and the inappropriateness of measures to manage crude production, and the decline in cultivation. 1. The selection of high-quality detoxification potatoes has shown that good varieties of potatoes and their high-quality detoxification can contribute about 60 per cent to potato production. Detoxification is early, strong, fat, strong, resilient and productive. Therefore, all detoxification g2 and g3 generations must be selected for production. 2. Precipitation of the soil selects the fertile soil, the flatness of the terrain, the ease of drainage, the depth of the crop, the estranged sandy soil or the frontier soil. It's not like it's an eggplant crop in front of it, so as to mitigate the disease. After the pre-harvest harvest, the leaves and strains are removed from the field in time for treatment, till about 30 crn before winter, to freeze the soil, to degenerate it, to receive rain and snow, to freeze the winter pests. And so we plant it in time, so that it can be so small, so small, so flat and so flat. 3. Scald seed. Cut-block sprouts require the planting of about 150 kg of potatoes per acre. Before the show, 20-25d put the potatoes in the warm and sunbath and plant 2-3d, while removing the sick potatoes, the rotten potatoes, and then cutting them. When cutting blocks, fully exploiting the top edge, the spiral is tilted to the top, and ends up in two or four steps by top bud, with one or two buds of each potato, weighing 25 to 30 g. When the dry knife is laid in a room with a temperature of 18-20°c, the layer is sprung, and it grows to about 3 cm
