Field management of the latest potatoes

Potato is an underground plant, and it is one of the four most important foods in the world. China is also the country with the largest potato production. In recent years, the market price of potatoes is also increasing step by step, and many people also see that the potato market begins to grow on a large scale, but it still needs good field management after sowing. So today I bring you the method of field management of potatoes. Let's take a look.

1. Soil and water management

Potatoes have a great demand for water at all stages of growth from sowing to ripening. To keep the soil moist, the soil water content should be kept at least 60%. After sowing, water is watered enough in each ditch to moist the soil, and herbicides are used to remove weeds in the field after sowing. In the seedling stage, if you encounter high temperature and drought, you must replenish the water in each ditch again. In the seedling stage, potatoes need water most, so you must keep the soil fully moist. However, 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. Therefore, we 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 it needs a lot of fertilizer. In order to improve the growth rate and health of seedlings, it is necessary to re-apply quick-acting fertilizer in the seedling stage of potatoes. Half a month after emergence, the first ploughing was carried out, and urea and potassium chloride were mixed and scattered on the soil. Start the second intertillage when the bud appears, using compound fertilizer and urea to spread in each potato hole, but be careful not to let the stem of the potato touch the fertilizer when using chemical fertilizer. Prevent the stem from touching the fertilizer and getting burned.

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 it is necessary to control potato diseases and insect pests in the process of potato growth. 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, and if fungal diseases are found, pesticides should be used in time to prevent further aggravation. Anke manganese zinc and other agents 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 for harvest. Stop watering 1-2 weeks before harvest, and cut off some of the stems and leaves in the ground a week before harvest, so that potatoes can finally ripen in the ground. Harvesting is best carried out on a sunny day, and care should be taken when digging to avoid harming potatoes. And dug out potatoes to avoid long-term exposure to the sun, bean skins will turn green after being exposed for too long, affecting the appearance and quality.

The above is the field management that needs to be paid attention to after sowing potatoes. It is easier to manage potatoes in the field to get high-yield and high-quality potatoes. Many growers still stick to their previous planting habits and don't care after planting them, but now according to scientific management methods, potatoes can become your source of income.
