1、 When is the best time

The planting time of potatoes should be determined according to the temperature. It is most appropriate to plant potatoes from March to April in spring, from September to October in autumn and from December to January in winter. Seed potatoes can germinate and grow when the soil surface temperature reaches 5-8 ℃, and the suitable temperature for growth is about 15-20 ℃. China has a vast geographical area and the climate in different regions is different, so the sowing time is also different. Only when the temperature meets the growth demand can they be sown and planted, but it is best to sow in time and early

2、 Planting method

1. Select seed potatoes: before planting potatoes, you must select healthy and full seed potatoes. Selecting appropriate seed potatoes can improve the planting survival rate

2. Soil preparation and fertilization: in order to promote the growth of potatoes, we must select the soil for sowing, provide fertile and loose soil, deeply plough and fine adjust in advance, apply base fertilizer to the soil, and use rotten organic manure

3. Sprouting and cutting: you can cut and sprout 1-3 days before sowing. Prepare a sharp knife in advance, disinfect it in advance, and then cut the seed potato into small seed blocks to ensure that each seed block has healthy bud eyes

4. Sowing: sow potato seed blocks into the soil, avoid contact with chemical fertilizer, and cover the soil after sowing

5. Field management: do a good job in field management after sowing, check seedlings in time, apply fertilizer in time, and pay attention to the prevention and control of diseases and pests
