The latest key points of Potato Management in the Middle and late stage

Potato is the potato that we often talk about in our daily life. Potato is a very important food crop in China, which has a very wide planting area. When planting potatoes, we should pay attention to adjust the management methods according to the growing period of potatoes. Especially in the middle and later period, how to manage the potato in the middle and later period? The following editor brings you the key points of potato management in the middle and later period, let's have a look!

1. Water and fertilizer management

In the middle and late stage of potato, it is the key period of potato tuber expansion. Therefore, the demand for water and fertilizer will also greatly increase during this period, so we must do a good job in water and fertilizer management. To meet the water and fertilizer needs of potato growth, it is necessary to start watering and fertilizing potato tubers when they are about the size of walnuts. Because potatoes have a high demand for potassium, we should pay attention to increasing the proportion of potash fertilizer. In watering, can be combined with topdressing nitrogen and potassium fertilizer, generally once every ten days or so, twice in a row or so. The soil should be watered in time when the soil is too dry, and drainage should be done well when there is too much water in the same way.

2. Ploughing and weeding

After entering the middle and later stage, the growth of potato is relatively large. Therefore, we also need to do a good job of weeding in mid-tillage, which is mainly to improve soil permeability, promote normal breathing of potato roots, improve soil structure, and ensure normal expansion of potato tubers. Then we should weed in time to avoid too many weeds to snatch the nutrition of potatoes. And the soil should be cultivated at the root of the potato, and reasonable ploughing and weeding is the key measure to increase the potato yield, so we must pay more attention to it.

3. Pest control

There are also many diseases and insect pests in the middle and later stage of potato, among which the common pests are aphids, grubs and so on. Insect pests will harm the roots and leaves of potato, absorb plant juice and so on, and seriously affect the normal growth of potato. And aphids are also very likely to carry viral pathogens, resulting in potato diseases, thus reducing yield. Therefore, we should strengthen prevention, disinfect the garden regularly, and dispose of plants with diseases and insect pests in time. Remove the affected parts, check the specific diseases and insect pests, and then take corresponding measures to use the corresponding agents for disinfection.

4. Timely harvest

The growing period of potatoes is not very long, usually about 4 months. And in the later stage of potato, it is also necessary to do a good job in harvesting potatoes. When the stems and leaves of the aboveground part of the potato are withered and yellow and the tubers are easy to separate, they can be harvested at the right time. When harvesting, it should not be carried out in overcast and rainy days to avoid reducing the storage performance of potatoes. When harvesting, we should be careful not to let the potato produce wounds and avoid causing postharvest diseases. At the same time, we should pay attention to the harvest time, not too early and too late, otherwise it will have a great impact on the yield and quality of potatoes.

The above is a brief introduction to the main points of potato management in the middle and later stage. That's all for today's introduction. This article is for reference only. I hope it can help you all.
