What happened to the latest dead cucumber seedlings?

When we plant cucumbers, we often encounter a lot of things that are harmful to the growth of cucumbers. One of the most common is dead seedlings, cucumber seedlings die for a variety of reasons after breaking the soil. As a result, the yield of cucumber decreased sharply, and the planting efficiency of farmers was seriously affected. So what happened to the dead cucumber seedlings? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Excessive fertilization

When planting cucumbers, many friends blindly apply a lot of fertilizer in order to increase the yield of cucumbers. And did not control the application of chemical fertilizer, resulting in too much fertilizer in the soil, excessive concentration, which is very disadvantageous to the growth of cucumber seedlings. The heat generated is too large to cause the seedlings to be burned out, and in the high temperature weather, water evaporation is relatively fast, resulting in the phenomenon of dead cucumber seedlings. Therefore, when we apply fertilizer, we should pay attention to control the amount of fertilizer application, do not apply too much, reasonably match the proportion of chemical fertilizer and farm fertilizer, avoid fertilizer damage to burn seedlings and reduce the phenomenon of dead seedlings.

2. Overwatering

There is a great demand for water in the growth of cucumber, especially in the expansion period, if the water is insufficient, it will have a great impact on the yield of cucumber. Therefore, many friends will apply a lot of water when watering, in fact, this is also wrong. We should also pay attention to control the amount of water, not too much watering, especially during the seedling period. If there is too much watering or there is no timely drainage on rainy days, then the seedlings will produce waterlogging damage, resulting in root water retting roots, resulting in the emergence of new Siyang County. Therefore, when watering, we should reasonably water the cucumber according to the growth stage of the cucumber to ensure the normal growth of the cucumber.

3. Causes of drug damage

The production capacity of cucumber is relatively strong, and the economic benefit is also good. However, the resistance to diseases and insect pests of cucumbers is relatively poor, so vegetable farmers will be accustomed to drug control. If the pesticide is used improperly or too much leads to too high concentration. Then it is very easy to cause drug damage to cucumbers, resulting in dead seedlings. Therefore, in the prevention and control of diseases and insect pests, we should pay attention to the rotational use of a variety of pesticides. At the same time, we should pay attention to all kinds of taboos and prepare pesticides reasonably to avoid excessive concentration of pesticides. In summer, spraying should not be carried out during the period of high temperature at noon to protect cucumber plants.

4. The cause of disease

As I just said, there are still many diseases in cucumbers. Therefore, disease is also a major cause of cucumber seedling death, in which our common diseases are Fusarium wilt, downy mildew and sudden drop disease, which will lead to cucumber death. Therefore, when we plant cucumbers, we should pay attention to the prevention of diseases. Strengthen field management, regularly do a good job of disinfection, control the amount of water and fertilizer, maintain a suitable environment to promote the growth of cucumber. After finding the disease, we should find out what the disease is in time, and then take corresponding measures to prevent and control the disease to avoid expanding the disease.

The above is a brief introduction to what happened to the dead cucumber seedlings. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
