Causes of death of watermelon seedlings in slow seedling stage

Watermelon can be said to be one of our national fruits, which has a very large market demand in our country, and it is basically planted everywhere. When growing watermelons, watermelons need to go through many growth periods. Among them, the slow seedling stage is one, but the phenomenon of dead seedlings often occurs in the slow seedling stage of watermelon. So what is the reason for the death of watermelon seedlings in slow seedling stage? Let's take a look at it with the editor.

1. Low temperature and high humidity

After the watermelon seedlings are planted, the requirements for temperature and humidity are relatively high. If you encounter a low-temperature and high-humidity environment at the slow seedling stage after planting, such as a long-term overcast and rainy day, resulting in too low ground temperature and too much humidity. Or when the soil is heavy, too much watering, and the soil is difficult to breathe, it is easy to lead to watermelon seedlings retting root phenomenon, resulting in dead seedlings. Therefore, after the watermelon seedlings are planted, we must pay attention to control the temperature and humidity, do a good job of ventilation, maintain the temperature and humidity in the field, and ensure the normal growth of watermelon seedlings.

2. the quality of planting is poor.

In planting, planting quality is very important, planting quality will directly determine the growth ability of watermelon after planting. On the other hand, if the seedlings are planted, the nutrient clods are not concentrated, the soil moisture is insufficient and there is little water for fixed roots. Or when the planting hole is too small, melon seedlings are too shallow, and so on. When the seedlings encounter high temperature environment, they are very easy to die. Therefore, when we plant, we must dig the planting hole strictly according to the requirements, control the planting depth and nutrition, and ensure that the seedlings pass through the slow seedling stage as soon as possible.

3. Improper fertilization

Fertilization is also very important when planting watermelon seedlings. Fertilization is the main way for watermelon seedlings to obtain nutrition, and if fertilization is not appropriate, such as shallow fertilizer and large pieces of feces. It will cause the seedlings planted on the dung block to burn easily, resulting in the death of seedlings. And fertilizing too much, uneven and so on, then the fertilizer will also produce a lot of heat to burn out the seedlings, but also prone to the phenomenon of dead seedlings. Therefore, we should have a reasonable fertilization method, which should not only provide adequate growth nutrition for seedlings, but also avoid the phenomenon of burning seedlings and dying seedlings.

4. Diseases and insect pests

The damage of diseases and insect pests is also one of the main reasons for the death of watermelon seedlings at slow seedling stage. Especially in some continuous cropping soil plots, soil-borne diseases and insect pests are very serious. Both diseases and insect pests will cause serious harm to the roots and young stems of watermelon seedlings. It leads to the disease of seedlings, resulting in serious seedling death. Therefore, we also need to do a good job in the prevention and control of diseases and insect pests, and use corresponding chemicals for different diseases and insect pests to prevent watermelon seedlings from dying by diseases and insect pests.

The above is a brief introduction to the cause of death of watermelon seedlings in slow seedling stage. That's all for today's introduction. This article is for reference only. I hope it can help you all.
