Prevention and remedial measures of growing Potato seedlings without Potato

Potatoes are the most common vegetables in our lives, and for growers, what they fear most is that potatoes grow but do not produce potatoes, especially in spring. Once it happens, it will have a great impact on the yield of potatoes, so preventive and remedial measures need to be taken. Let's take a look at it with the editor.

1. Cause of occurrence

There are many reasons why potatoes only grow seedlings but do not produce potatoes, for example, when sowing is too late, varieties cannot be introduced, varieties are not suitable for planting in the local environment, the soil is too shallow, or the soil is too dry. It is possible to cause potatoes to grow seedlings but not to produce potatoes.

2. Preventive measures

In order to obtain high yield, the excellent varieties with detoxification, very early maturity or early maturity should be selected when selecting varieties, and the measures such as sprouting, drying and timely early sowing should be adopted to promote their early growth and rapid development, so that the formation and expansion period of potato pieces are under more suitable environmental conditions. in order to obtain higher yield. When cultivating the soil, we should pay attention to the thickness of not less than 12 cm. If the thickness of the covered soil is not enough, we should cultivate the soil 1-2 feet with the seedling growth after emergence. The soil temperature will change sharply if the covering soil is too thin, and the thicker sugar beet can end at a relatively balanced cool ground temperature. Nitrogen fertilizer is beneficial to plant growth, but if topdressing is too late, it is very easy to cause stem and leaf growth, which is not conducive to tuber and tuber expansion, so it is necessary to apply nitrogen fertilizer timely and reasonably, not too late.

3. Remedial measures

After the discovery, we should find out the cause in time, remedy it in time, watering the small water frequently and keeping the soil moist, which is beneficial to the similarity of the potato to the fertilizer and water, and can also reduce the ground temperature in the late spring and promote the expansion of potato blocks, but we should be careful not to get fat and water. According to the situation of the soil, for those who have not been closed and did not cultivate the soil in the later management, we can cultivate the soil appropriately according to the situation and thicken the soil layer, which can reduce the effect of external high temperature on the expansion of potatoes. From the late growth stage to the tuber-forming stage, we should control the prosperity in time, spray multiple frustrations, control the plant growth, the proportion of tall and medium potatoes, and increase the yield.

The above is the introduction of potato prevention and remedial measures, hope to help you, want to know more related knowledge, please pay attention to us.
