Best time to plant potatoes in winter

Potatoes are grown in all parts of China, north and south. Generally speaking, potatoes can be harvested 120-150 days after planting, depending on the variety and climatic conditions. If you want to get a high yield when growing potatoes , you must master the time and method. Here, the editor will introduce the best time to plant potatoes in winter. Let’s take a look.

1. The best time to plant potatoes in winter

The best time to plant potatoes in winter is generally around October to December each year. Specifically, potatoes can be planted in the southern region in winter from October to November and harvested in February to March of the following year. In the northern and northwestern regions, planting generally begins in late April to early May and harvests in September or October. In the dual-crop areas of the Central Plains and Central South, crops are usually planted in spring from February to March and harvested in June to July. Some crops are planted in August and harvested in October to November.

2. How to plant potatoes in winter

1. Choose the variety

Choose suitable high-yield potato varieties according to local climate and soil conditions. Different varieties have different adaptability to the environment. Choosing varieties with strong disease and pest resistance and high yield is the key to high yield.

2. Soil preparation

Potatoes prefer deep, well-drained soil rich in organic matter. Deep plowing should be carried out before planting to increase the soil's aeration and water retention capacity, while adjusting the soil pH to keep it neutral or slightly acidic.

3. Reasonable fertilization

Potatoes need adequate fertilizer to support their growth, especially nitrogen, phosphorus and potassium fertilizers. Apply sufficient base fertilizer, such as fully decomposed organic fertilizer , and appropriate amount of chemical fertilizer to ensure adequate nutrient supply during potato growth.

4. Seed potato processing

Choose healthy seed potatoes that are free of pests and diseases. You can cut the seed potatoes into pieces, making sure there are eyes on each piece. After cutting, the pieces can be disinfected to prevent diseases and pests.

5. Germination

Soak the seed potatoes in the humic acid solution for 10 minutes, pick them up and bury them in a moist sand bed, cover them with a film for germination, which can ensure fast and uniform germination.

6. Planting seeds

When the daily average temperature is 15-25℃, sowing can be done, and the planting density should be reasonably arranged according to soil fertility. Under normal cultivation conditions, about 6,000 potatoes can be planted per acre.

The above is an introduction to the best time to plant potatoes in winter. When planting potatoes in winter, you should also pay attention to choosing land that has not been planted with potatoes in the past 2-3 years. The soil should be loose and breathable, with a deep and fertile soil layer and a high organic matter content. This is more conducive to the development and expansion of underground potato tubers and increases later yields.
