How to manage potatoes during the expansion period

Everyone should have eaten potatoes. Potatoes are a kind of tuber vegetables that are very good for human growth. They are very rich in nutrients and are very popular in the market. Although the current market price is not high, but there is a large "fan group". So it is cultivated in all parts of our country. Growing potatoes has different management at each growth stage, and what the editor is going to talk about today is how to manage potatoes during the expansion period. Let's take a look at it.

1. Topdressing

Potatoes have a large demand for nutrition during the whole growth period, especially during the expansion period, and the demand for potash fertilizer is relatively high. When fertilizing, we should work with loosening the soil according to the growth of potatoes to improve the permeability and fertility of the soil. It is necessary to cover the soil in time after fertilization to prevent fertilizer from burning roots.

2. Loosen the soil

Loosening the soil is a necessary work that we have to do, and we should be careful not to destroy the plastic film when loosening the soil. The main purpose of loosening soil is to promote the root, and when watering and topdressing, it is easier to penetrate and improve the absorptive capacity of the soil. The growth of the plant is more robust, which can effectively help potatoes to expand better and enhance the commercial value of potatoes.

3. Watering

In the potato expansion period of the hand, to do a good job of watering, but to pay attention to the use of small water drip irrigation, do not flood. Prevent the impact of water from excessive, causing damage to the root of the plant. The expansion period is the time when potatoes need the most water, but we should also pay attention to watering water, not too much, and discharge the excess water in time in cloudy and rainy weather, otherwise it will rett root and rotten fruit.

4. Weeding

Weeding is very important because weeds have a great impact on plant growth. If there are too many weeds in the field, it will compete with potatoes for nutrients and water, especially in the expansion period, too many weeds rob the growth nutrition, resulting in swelling hindrance and reduce the quality of potatoes. When weeding, try to uproot weeds to prevent secondary growth.

5. Pinch buds

Pay attention to the number of buds on the plant during the potato expansion period and keep a small amount or all of them. Because the bud blooming and growth needs a lot of nutrients, if the bud is not pinched in time, it will compete for the nutrition when the tuber is enlarged, resulting in the obstruction of tuber expansion. Therefore, choking buds can promote the transfer of nutrients to the tuber, improve the expansion speed of the tuber and enhance the quality.

6. Cultivate the soil

It is necessary to cultivate the soil at least twice when the potato is finally ripe, each time during the expansion period, the first time when the stem is enlarged and the second when the tuber expands. Each time the height of the soil is 3-5 cm, the main purpose of soil cultivation is to prevent the tuber from exposing the ground after expansion and affect the growth in the later stage.

The above is the management method during the potato expansion period, in fact, there is also pest control, but pest control is a good work to be done throughout the growth period, and the editor did not elaborate on it. We should pay attention to observe the basic situation of the plant, check the abnormal situation in time, and take corresponding measures. Only by doing a good job in the prevention and control of diseases and insect pests can potatoes grow better and increase their yield.
