South potato planting method
1, soil conditions
When planting potatoes, we should choose loose and fertile soil with good drainage, add peat and decomposed leaves to the soil to increase the fertility of the soil, and apply some decomposed base fertilizer to meet the growth needs of potatoes.
2. Potato seed treatment
When planting potatoes, we should follow the principle of cutting before planting. The day before sowing, evenly cut dormant seed potatoes with buds, complete appearance and no pests and diseases into small pieces of 25-30g, ensuring that each piece has bud holes. Before sowing, soak the seed blocks in hot water for 30 to 40 minutes.
Step 3: sow.
When sowing, the seed blocks are evenly buried in the soil to ensure the depth of 25 cm and the spacing between the seed blocks is 3-5 cm. After filling the soil, water should be poured once in time to ensure that water can penetrate to the bottom of the soil and keep the soil moist. Covering the soil surface with a plastic film plays the role of heat preservation and moisture retention.

After potatoes are planted, they can be watered once to keep the soil moist and promote them to take root and sprout as soon as possible. After potatoes enter the growth period, you need to water the plants every 3-5 days to meet their growth needs and maintain the normal growth of potatoes.
