What causes tomato seedling death
Tomatoes can be said to be a beauty treasure, so they are deeply loved by female consumers. With advances in cultivation techniques, 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 it, so the editor has put together the content below, and interested friends can take a careful look.
1. Symptoms before tomato seedling death
During tomato cultivation, seedling death can occur in many cases, so does it mean the seedlings die directly? Or is there a period of symptoms beforehand? Generally, if you observe carefully before tomato seedlings die, there are warning signs. For example, tomato seedlings grow slowly or do not grow at all; tomato seedlings are very thin and weak, with poor nutrition; the leaves of tomato seedlings 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, there are also symptoms such as grayish-white mold layers appearing on tomato seedlings, or a water-soaked appearance.
2. Causes of tomato seedling death
Why do tomatoes die after planting? If the tomato variety is not chosen properly, the seedling quality is poor, or the seedlings are damaged when pulled up, seedling death can occur after planting. If the planting site is too clayey, or is continuous cropping land, or the soil permeability is too poor, it can 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 too much fertilizer is applied and the fertilizer concentration is too high, it can all 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 pests and diseases, such as root rot, nematode disease, bacterial wilt, stem rot, basal rot, aphids and so on.
3. Prevention and control measures
If we understand why tomato seedling death occurs during cultivation, 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 during continuous rain or heavy rain, drainage should be done in time to avoid water accumulation that causes root rot. When fertilizing, it should be done according to the growth stage of the tomatoes. During the seedling stage, nitrogen fertilizer is mainly used to promote seedling growth, but it should also be combined with phosphorus and potassium fertilizers, and nitrogen fertilizer should not be used excessively. To avoid excessive nutrient concentration, remember to water after fertilizing. There is one more thing 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 pests and diseases, use specialized agents for prevention and control.
The above is what the editor wants to share today about the causes of tomato seedling death and prevention and control methods. Here, due to limited energy and time, the editor has not explained the specific use of the agents. If you need it, you can consult relevant professionals locally, or leave a message for the editor.
