Field Management of Potato

Potatoes, also known as potatoes, potatoes and so on, occupy an important position in both western food and Chinese food and are very popular. So, how should potatoes be managed in the field?

1. Soil and water management

Potatoes have a great demand for water at all stages from sowing to ripening. In order to keep the soil moist, the soil water content should at least be more than 60%. After sowing, water should be watered enough in each ditch to moist the soil. At the same time, herbicides are used to remove weeds in the field after sowing. If you encounter high temperature and drought in the seedling stage, you must replenish the water in each ditch again in the seedling stage. Potatoes need water most, so be sure to keep the soil fully moist, but in the final ripening period of potatoes, water should not be too much, because too much water will make the ventilation between the soil worse, potatoes can not breathe, resulting in rotten fruit, so the mature period should pay attention to field drainage in cloudy and rainy weather.

2. Ploughing and fertilization

Potato is not only a crop with high water demand, but also has a high yield, so the amount of fertilizer needed is also very large. The higher the sufficient yield of fertilizer application is, the more quick-acting fertilizer should be applied to improve the growth rate and health of potato seedlings. Half a month after emergence, the first intertillage should be carried out, urea and potassium chloride should be mixed on the soil, and the second intertillage should be started when the buds appear. Compound fertilizer and urea are scattered in each potato hole, but when using chemical fertilizer, you should be careful not to let the stem of the potato touch the chemical fertilizer to prevent the stem from touching the chemical fertilizer.

3. Prevention and control of diseases

Diseases and insect pests have always been a factor affecting the yield and quality of potatoes and even all crops, so in the process of potato growth, potato diseases and insect pests must be well controlled. there are a series of diseases such as early and late blight, dry rot and so on. first of all, when selecting varieties, we can choose disease-free varieties, appropriate sowing time in advance, if fungal diseases are found. To use pesticides for prevention and control in time to prevent further aggravation, Anke manganese zinc and other chemicals can be sprayed once a week for about a month.

4. Timely harvest

When it is found that the stems and leaves of potatoes begin to turn yellow, it means that the potatoes are basically ripe and ready to be harvested. Stop watering 1-2 weeks before harvest, and a week before harvest, cut off part of the stems and leaves in the ground to allow potatoes to ripen in the ground. Harvesting should be carried out on a sunny day, be careful when digging, avoid damage to potatoes, and dig potatoes to avoid long-term exposure to the sun. Bean skins will turn green after being exposed for too long, affecting their appearance and quality.
