1. Potato seed potato selection: select potato seed potato with a weight of 70-80g. You can't choose broken potatoes with patches. You need to choose potato seeds with more buds, which is beneficial to the smooth growth of seedlings after potato planting.

2. Cultivated land: It is necessary to plough the soil to a depth of 30cm to make the soil more loose. You can add a proper amount of manure as base fertilizer before turning over the soil, and then turn over the soil to combine the two to provide growth nutrients for potatoes.

3. Cutting into pieces to accelerate germination: Before planting, you need to cut the potatoes into pieces to accelerate germination, disinfect the knives with alcohol, then cut the potatoes into 3 to 4 pieces with small buds, dry them and then sow them.

4. Planting and covering soil: turn the processed potato pieces over the ploughed land, and pay attention to the fact that the potato bud eyes need to face upwards, so as to facilitate the better growth of potato buds. Then cover with thin soil, so that the potatoes can grow smoothly in a warm and moist environment.

5. Post-maintenance: After potato planting, it needs to be watered once to provide suitable temperature and light conditions for potatoes. After one month, do a good job of weeding to avoid absorbing too much nutrition.
