How to plant potato seeds in potted plants?

When planting potatoes in potted plants, first disinfect the seeds with alcohol, lysol or 0.5% potassium permanganate solution for 5-10 minutes, and cut them into pieces 3-5 days before sowing. After dressing seeds, put them in ventilated places, and sow them when wounds heal. After the seeds are treated, the seeds are sown in a basin prepared in advance, and the soil covering thickness is 3-5cm.

What month is the best time to plant potatoes?

1. Northeast China, Gansu Province, Qinghai Province and other northwest regions are generally planted in spring (from mid-late April to early May) and harvested in autumn. Usually only one season of potato can be planted in a year, which is called the north and northwest one-season planting area.

2. Shandong, Hebei, Henan, Shanxi, Jiangsu, Hunan, Hubei and other provinces and regions planted two seasons of potatoes a year. Among them, spring sweet potatoes are sown in February and March in Shandong, Hebei and other central plains, and harvested from June to July; autumn sweet potatoes are sown in August and harvested from the end of October to the beginning of November; spring sweet potatoes are sown in January to February in Jiangsu, Zhejiang and other central and southern provinces, and harvested from May to June; sowing in September and harvesting in December. These areas are known as the Central Plains and Central and South China Two-Season Crop Areas.

3. Guangdong, Guangxi, Hainan, Yunnan, Guizhou and other places can use the gap after harvest of autumn rice to plant a season of potatoes. Sowing is usually done from mid to late October to November, and harvesting is done in February to March of the next year. Because most of the growing season is in winter, these areas are usually called southern winter farming areas.

2 How to grow potatoes?

1. sowing

To timely early soil preparation fertilization sowing, so that the whole growth period of potato in a relatively cold, low temperature season, so that potato formation and expansion to avoid high temperature period. Pay attention to the thickness of the soil. Generally, the thickness of the soil is not less than 12 cm. If the soil thickness is insufficient when sowing, cultivate the soil 1-2 times with the seedling growth after emergence. The soil cover is too thin, the ground temperature changes violently, and the stolons are easy to jump out of the ground.

2. fertilization

Potato fertilization is generally based on the principle of "mainly organic fertilizer, supplemented by chemical fertilizer, heavy application of base fertilizer, early application of topdressing". Because organic fertilizer is rich in organic matter, it is beneficial to fertilize, loosen soil, improve soil fertility, and is more conducive to potato tuber expansion and root growth. Potato growth period needs the most water and fertilizer is flowering stage, and this is also the season of rising temperature and increasing rainfall, and it is also the stage of organic fertilizer gradually ripening and decomposing to release nutrients.

3. field management

The potato plant is divided into two parts: aboveground and underground. The aboveground part has aboveground stems, pinnate compound leaves, buds and fruits; the underground part has underground stems, roots, stolons and tubers. Whether the aboveground part bears fruit or not is related to the variety and external environmental conditions. The same variety will bear fruit or not in different years and different planting time in the same year.
