When is the best time to plant potatoes? Can I plant it in summer?

Potato is called potato in Yunnan, and some people call it yam earth egg. Potato is its real written name. Potato is an annual plant of Solanaceae, which is mainly commercialized with nutrient-rich underground tubers.

Potatoes are rich in starch and vitamins, which can not only replace vegetables and fruits, but also be processed into various convenience foods, and are deeply loved by people.

Summer is hot, with high temperature and long sunshine, which is not suitable for planting potatoes. It belongs to plants with short sunshine and cold climate. Planting potatoes in summer is easy to cause non-emergence, excessive growth and diseases, and will seriously reduce production, which is not an ideal planting season.

Usually potatoes can be planted twice a year, and the best planting season is spring and autumn. Most people like planting in spring, and the Xiaoya family is no exception. They also grow two kinds of potatoes. Next, I will take potatoes planted in spring as an example to talk about matters and problems that should be paid attention to.

First, planting time

Early-maturing varieties should be selected for potatoes planted in early spring, and attention should be paid to planting according to local temperature. Potatoes had better be planted in the field after first frost, or they will freeze to death if they germinate too early. Water them until they germinate, or they will rot.

Second, base fertilizer should be applied adequately.

Potatoes are high-yield products that need fertilizer most. Generally, sufficient base fertilizer is applied at one time before sowing, and no fertilizer is applied after emergence. The base fertilizer is mainly organic fertilizer, supplemented by chemical fertilizer, so that nitrogen, phosphorus and potassium can be used together.

Third, properly store seed potatoes and properly accelerate germination.

Pay attention to temperature and humidity when storing potato seeds to avoid excessive temperature difference and uneven bud length. Potatoes without spores should be heated to germinate.

Fourth, prevent the production of green potatoes.

When we grow potatoes, the soil should not be too thick, nor too thin, too thick, airtight and perishable. If it is too thin, it will be exposed to light, which will turn the grown potatoes green and affect the quality.

Therefore, the soil should be compacted gently before planting, so that it is compacted but not solid. You can also spread a layer of straw on the border without leaving white space to avoid the growing potatoes turning green.

Verb (abbreviation of verb) pest control

The main diseases of potato are early blight, late blight, ring rot, soft rot and virus disease. Pests include potato ladybugs, mites and aphids. In order to avoid the occurrence of epidemic diseases, we should pay attention to planting non-solanaceae crops in rotation for more than three years. Late blight can be planted with disease-free potatoes, or soaked in formalin solution for five minutes before planting, dried and sowed.

Intransitive verb harvest

When the leaves and stems of potatoes turn yellow and the leaves at the base turn yellow and fall off, they can be dug. Usually it is carried out in sunny, cool and dew-free conditions, and then it is placed in a cool place and spread out to dry to prevent sun and rain. Pay attention to stop spraying any chemicals within seven days before excavation.
