How to manage the latest potato expansion period

Potato everyone should have eaten, potato is a very good tuber vegetable for human growth, its nutrients are very rich, very popular in the market. Although the current market price is not high, but there is a large "fan base." It is cultivated everywhere in our country. Planting potatoes has different management at each stage of growth. What Xiaobian wants to talk about today is how to manage potatoes during the expansion period. Let's take a look below!

1. Topdressing

The whole growth period of potato needs more nutrition, especially in the expansion period, and the demand for potassium fertilizer is relatively high. When fertilizing, we should carry out the work together with the loosening according to the growth of potatoes to improve the permeability and fertility of the soil. After fertilization, cover soil in time to prevent fertilizer from burning roots.

2. Loose soil

Loosening is a necessary job for us to do. Be careful not to destroy the mulch film when loosening the soil. The main purpose of loosening soil is to promote root taking and to improve soil absorption capacity by making it easier to penetrate when watering and topdressing. The growth of plants is more robust, which can effectively help potatoes expand better and enhance the commodity value of potatoes.

3. Watering

In the potato expansion period of the hand, to do a good job watering, but pay attention to the use of small drops of irrigation, avoid not big water. Prevent the impact of water is too large, causing damage to the roots of plants. Expansion period when the potato water demand is the largest time, but also pay attention to watering, not too much, rainy weather will also be timely discharge of excess water, otherwise it will be rotten roots fruit.

4. Weeding

Weeding is very important because weeds have a great impact on plant growth. Too many weeds in the field will compete with potatoes for nutrients and water, especially in the expansion period, too many weeds rob the growth nutrition, resulting in expansion obstruction and reducing 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 when the potato is expanding, leaving a few or pinching them all. Because flower buds need a lot of nutrients to bloom and grow, if they are not pinched in time, they will compete for nutrients when tubers expand, resulting in blocked tuber expansion. Therefore, bud pinching can promote nutrient transfer to tubers, improve tuber swelling speed and enhance quality.

6. Soil cultivation

At least two times of soil cultivation should be carried out when the potato is planted to the final maturity. Each time the soil cultivation is in the expansion period, the first time is when the stem is expanded, and the second time is when the tuber is expanded. Each time the soil height is 3-5 cm, the main purpose of the soil is to prevent tubers from exposing the ground after swelling, affecting the later growth.

The above is the management method during the potato expansion period. In fact, there is also pest control, but pest control is a good job to be done throughout the growth period, so there is no detail in the small editor. Pay attention to the basic situation of the plant, check it in time when abnormal conditions occur, and make corresponding measures. Do a good job of pest control work, in order to make potato better growth, improve yield.
