What causes seedling death during the watermelon seedling recovery period?

Watermelon can be said to be one of our national fruits, with a very large market demand in our country, and it is basically grown in all regions. When growing watermelons, watermelons need to go through many growth stages. Among them, the seedling recovery period is one, but seedling death often occurs during the watermelon seedling recovery period. So what causes seedling death during the watermelon seedling recovery period? Let's take a look together with the editor below!

1. Low temperature and high humidity

After watermelon seedlings are transplanted, the requirements for temperature and humidity are relatively high. If during the seedling recovery period after transplanting they encounter a low-temperature and high-humidity environment, such as long periods of rainy days, causing the ground temperature to be too low and the humidity to be too high. Or when the soil is heavy and clayey, too much water is applied, and the soil is difficult to aerate, it is easy to cause root rot in watermelon seedlings, resulting in seedling death. Therefore, after transplanting watermelon seedlings, we must pay attention to controlling temperature and humidity well, do a good job of ventilation, maintain good field temperature and humidity, and ensure that watermelon seedlings can grow normally.

2. Poor transplanting quality

When transplanting, the quality of transplanting is very important. The quality of transplanting directly determines the growth ability of watermelons after transplanting. If during transplanting the seedlings have nutritional soil blocks that are scattered and not concentrated, insufficient bottom soil moisture, and too little rooting water. Or when the transplanting holes are too small and the melon seedlings are planted too shallowly. When the seedlings encounter a high-temperature environment, seedling death is very likely to occur. Therefore, when transplanting, we must strictly dig the transplanting holes according to requirements, control the transplanting depth and nutrition well, and ensure that the seedlings pass through the seedling recovery period as quickly as possible.

3. Improper fertilization

When transplanting watermelon seedlings, fertilization work is also very important. Fertilization is the main way for watermelon seedlings to obtain nutrients, and if fertilization is improper, such as shallow fertilization and large manure clumps. It will cause the seedlings planted on the manure clumps to be very prone to fertilizer burn, leading to seedling death. And if too much fertilizer is applied or it is unevenly applied, then the fertilizer will also generate a large amount of heat and burn the seedlings, and seedling death is also likely to occur. Therefore, we need a reasonable fertilization method, which must both ensure sufficient growth nutrients for the seedlings and avoid fertilizer burn and seedling death.

4. Damage from pests and diseases

Damage from pests and diseases is also one of the main causes of seedling death during the watermelon seedling recovery period. Especially in some soil plots with continuous cropping and repeated cropping, soil-borne diseases and insect pests are very serious. Whether it is disease or insect pests, they will cause serious damage to the roots and young stems of watermelon seedlings. Causing the seedlings to become diseased, thereby resulting in serious seedling death. Therefore, we must also do a good job in the prevention and control of pests and diseases, and use corresponding pesticides for different pests and diseases to prevent watermelon seedlings from dying due to damage from pests and diseases.

The above is a brief introduction to the causes of seedling death during the watermelon seedling recovery period. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
