Dead cucumber seedlings. What's going on?

When we grow cucumbers, we often encounter a lot of unfavorable conditions for cucumber growth. Among them, the most common is dead seedlings. Cucumber seedlings die for various reasons after breaking ground. As a result, the yield of cucumber dropped sharply, and the planting efficiency of farmers was seriously affected. So what happened to the dead cucumber seedlings? Today, Xiaobian will give you a brief introduction. Let's take a look at it together.

1. Excessive fertilization

When planting cucumbers, many friends will blindly apply a large amount of fertilizer in order to improve the yield of cucumbers. And there is no control of fertilizer application, resulting in excessive fertilizer in the soil, excessive concentration, the growth of cucumber seedlings is very unfavorable. The heat generated is too large to cause the seedlings to be burned, and in high temperature weather, water evaporation is relatively fast, resulting in the phenomenon of cucumber dead seedlings. Therefore, we should pay attention to controlling the amount of fertilizer when applying fertilizer, not applying too much, reasonably matching the proportion of chemical fertilizer and farm manure, avoiding fertilizer damage and burning seedlings, and reducing the phenomenon of dead seedlings.

2. Too much watering

Cucumber in the growth of water demand is greater, especially in the expansion period, if the water shortage, then the cucumber yield will cause greater impact. Therefore, many friends will apply a lot of water when watering, in fact, this is also wrong. We should also pay attention to controlling the amount of watering, not too much watering, especially during the seedling period. If too much watering or rainy days do not drain in time, then seedlings will produce waterlogging damage, resulting in root system by water, resulting in Siyang County new. Therefore, when watering, we should water reasonably according to the growth stage of cucumber to ensure the normal growth of cucumber.

3. Causes of phytotoxicity

Cucumber production capacity is relatively strong, economic benefits are also relatively good. However, cucumber disease resistance and pest resistance is relatively poor, so vegetable farmers will habitually use drugs to prevent and control. And if pesticides are used improperly or excessively, the concentration is too high. Then it is easy to cause cucumber phytotoxicity, resulting in dead seedlings. Therefore, when we control pests and diseases, we should pay attention to the rotation of multiple pesticides. At the same time, we should pay attention to various taboos, reasonably formulate pesticides, and avoid excessive pesticide concentrations. Summer can not be sprayed at noon high temperature period, protect cucumber plants.

4. Causes of disease

As mentioned earlier, cucumber diseases are still relatively high. Therefore, diseases are also a major cause of cucumber seedling death, among which our common diseases are blight, downy mildew and damping-off disease, which will lead to cucumber death. Therefore, when we plant cucumbers, we should pay attention to the prevention of diseases. Strengthen field management, do disinfection regularly, control water and fertilizer, and maintain a suitable environment to promote cucumber growth. After discovering the disease, we should find out what the disease is in time, and then take corresponding measures to prevent and control it, so as to avoid expanding the disease.

The above is a simple introduction to what happened to cucumber dead seedlings. Today's introduction is here, this article is for reference only, thank you for reading and support.
