How many times a year can potatoes be planted in the South?

The climatic conditions in the southern region are more suitable for the growth of potatoes, and the growth cycle is about 3 to 4 months. Compared to other crops, potatoes have a shorter growth cycle and can be harvested faster, thus improving economic benefits. So how many times a year can potatoes be planted in the south? Let’s take a look with the editor below.

1. How many times a year can potatoes be planted in the south?

1. Two-crop planting

In most parts of the south, such as the Yangtze River Basin, potatoes can usually be planted twice a year, once in spring and once in autumn. Spring planting generally takes place from January to February, while autumn planting takes place around September.

2. Three-crop planting

In some areas with warmer climates and longer frost-free periods, such as Yunnan and Guangxi, potatoes can even be planted three times a year. This is thanks to the fact that these areas provide more time and suitable temperature conditions for potato growth.

2. Potato planting methods in the south

1. Seed potato processing

Choose healthy, pest-free seed potatoes and cut them into 25 to 30 g pieces, making sure each piece has eyes. The cut seed potato pieces should be soaked in hot water for 30 to 40 minutes before sowing. After cutting, dip the cut surface with wood ash to prevent the wound from becoming inflamed by the wind.

2. Select the site and apply fertilizer

Potatoes prefer moderate moisture, but too much water can cause root rot. Therefore, before planting, make sure the soil is well drained and avoid waterlogging. Apply an appropriate amount of organic fertilizer , such as well-rotted farmyard manure, before planting to improve soil fertility. At the same time, you can also add an appropriate amount of compound fertilizer or potassium fertilizer as base fertilizer.

3. Planting seeds

Bury the seed potatoes evenly in the soil to a depth of about 25 cm, with a distance of 3-5 cm between the seed pieces. After filling, water it in time to ensure that the water can penetrate to the bottom of the soil and keep the soil moist. Cover the soil surface with a layer of plastic film to keep it warm and moist.

4. Field management

During the growing period, the plant needs to be watered every 3-5 days to meet its growth needs. Pay attention to replenishing nutrients in time and keeping the soil moist. In the early stages of growth, the soil should be watered and fertilized, and weeding should be carried out in a timely manner.

The above is an introduction to how many times potatoes can be planted in the south in a year. In the southern region, potatoes can generally be planted twice. The first planting time is between January and February in early spring, and the second planting time can be chosen in September.
