What are the latest causes of tomato seedling death
Tomato can be said to be a beauty product, so it is deeply loved by female consumers. With the advancement of planting technology, tomato yields have also been continuously increasing, so have you ever encountered the phenomenon of seedling death when growing tomatoes? Recently, the editor received messages asking about the causes of tomato seedling death and how to prevent and control tomato seedling death, so the editor sorted out the content, and interested friends can take a careful look.
1. Symptoms before tomato seedling death
During the tomato planting process, seedling death may appear in many cases, so does it mean the seedlings die directly? Or is there a certain period of symptom expression? Generally, before tomato seedlings die, if you observe carefully, there are signs of seedling death. For example, tomato seedlings grow slowly or do not grow at all for a long time; tomato seedlings are very thin and weak, with poor nutrition; the tomato leaves gradually turn yellow and wither, then the roots and stems also gradually dry up, lose water, and finally the whole plant dries up and dies, or rots and dies. Of course, some symptoms also show gray-white mold layers on tomato seedlings, or a water-soaked appearance, etc.
2. Causes of tomato seedling death
Why do tomato seedlings die after planting? If the tomato variety is improperly selected, the seedling quality is poor, or there is damage when pulling the seedlings, seedling death may occur after planting. If the planting site is too clayey, or is continuous cropping land, or the soil permeability is too poor, it will all cause seedling death. After planting, if the nutrients in the soil are insufficient to supply the growth of the seedlings, causing poor nutrition and no timely nutrient supplementation, or if the amount of fertilizer applied is too large and the fertilizer concentration is too high, it will also cause seedling death. Seedling death after planting may also be caused by too much water in the field, causing root rot and plant death, or by severe water shortage, causing the plants to dry up and die. Finally, there is the harm to tomato seedlings from diseases and insect pests, such as root rot, nematode disease, bacterial wilt, stem rot, basal rot, aphids, and so on.
⟦NL>3. Prevention and control measures
If we understand why seedling death occurs during tomato planting, then prevention and control become very simple. We should choose high-quality varieties with good resistance and high-quality, robust tomato seedlings, and plant them in plots with good soil permeability, good drainage, and fertile soil. After planting, water appropriately to keep the soil moist, but in case of continuous rain or heavy rain, drainage should be done in time to avoid water accumulation, which can lead to root rot. When fertilizing, it should be done according to the growth stage of the tomato. The seedling stage is mainly based on nitrogen fertilizer to promote seedling growth, but it should also be combined with the use of phosphorus and potassium fertilizers, and the use of nitrogen fertilizer should not be excessive. To avoid excessive nutrient concentration, remember to water after fertilizing. There is one more point to note here: to avoid soil compaction, which affects soil permeability and nutrient absorption, remember to loosen the soil after rain or watering. Finally, for different diseases and insect pests, use specialized agents for prevention and control.
The above are the causes of tomato seedling death and the prevention and control methods that the editor wants to introduce to you today. Here, due to limited energy and time, the editor did not specifically explain the use of agents.
