---

The breeding time for potato seedlings is from April to May. At this time, the temperature is around 15-20℃. If the climate is different, the seedling raising time can be delayed. Choose seed potatoes of the right size and plant them in the soil. The distance between each piece is 3 cm and covered with a layer of soil 2-3 cm thick. Then use mulch to keep it warm, and then remove it after the seedlings grow. When the temperature is above 20°C, ventilation should be strengthened to prevent seedlings from burning due to high temperatures. Spray water regularly to keep the substrate moist.

1. Seedling cultivation time

The seedling cultivation period of potato is generally from April to May. At this time, the temperature is not very high, which is conducive to the growth of seedlings. At the same time, the light is relatively sufficient, and the temperature is between 15-20°C. If the climate is different, the seedling cultivation time can also be delayed.

1 3. Seed potato selection: Potatoes are rarely propagated by seeds. Instead, seed potatoes, which are their tuberous roots, are chosen. Select some seed potatoes that are free from diseases and insect pests and have no surface damage, weighing between 100-250 grams.

2. Planting: Potatoes are generally planted on a large scale , the distance between each seed potato is about 3 cm. After it is lined up, cover it with a layer of soil of 2-3 cm. The soil should not be too thick to avoid affecting the emergence of seedlings.

3. Insulation measures: According to different potato varieties, the insulation measures are also different. Early maturing varieties use three layers of greenhouses, small arches and mulch for insulation, while conventional varieties use two layers of small arches and mulch. After the seedlings emerge, the mulch film should be removed to avoid affecting the growth of the seedlings.

4. Maintain ventilation: When the temperature is above 20℃, It is necessary to strengthen the ventilation of the greenhouse to prevent the temperature from being too high and burning the seedlings. At the same time, water should be watered in time after the soil is dry to ensure that the environment is moist.
