What is the cause of tomato seedling death?

Tomato can be said to be a kind of beauty sacred product, so it is deeply loved by the majority of female consumers. With the progress of planting technology, the yield of tomato cultivation is also increasing, so we do not know if we have encountered the phenomenon of dead seedlings when planting tomatoes? Recently, the editor has received a message to inquire about the causes of dead tomato seedlings and how to prevent and cure dead tomato seedlings, so the editor has sorted out the content, and interested friends can understand it carefully.

1. Symptoms of tomato before death.

In the process of tomato planting, dead seedlings may appear in many cases, so is it directly dead seedlings? Or do you have symptoms for a certain period of time? In general, if the tomato is carefully observed before it dies, it is a sign of dead seedlings. For example, tomato seedlings grow slowly or do not grow all the time; tomato seedlings are very weak and malnourished; tomato leaves slowly turn yellow and wither, and then the rhizomes slowly dry up and lose moisture, and finally the whole plant dries up and dies, or rot and die. Of course, some symptoms are that tomato seedlings appear gray-white mildew layer, or show water stains, and so on.

2. The cause of tomato seedling death

Why do tomatoes die after planting? If the tomato varieties are not selected properly, the quality of the seedlings is poor, or if there is some damage when pulling out the seedlings, the dead seedlings may appear after planting. If the stickiness of the planting land is too heavy or the soil permeability is too poor, it will cause dead seedlings. After planting, the nutrients in the soil are not enough to supply the growth of seedlings, resulting in malnutrition and no timely supplement of nutrition, or too much fertilizer application, too high fertilizer concentration, will lead to the death of seedlings. After planting, the dead seedlings may also be caused by too much water in the field, resulting in root rot, leading to plant death, or serious lack, leading to plant dry death. Finally, there is the harm of diseases and insect pests to tomato seedlings, such as root rot, nematode disease, bacterial wilt, stem rot, basic rot, aphids and so on.

3. prevention and control measures

If we understand why dead seedlings appear in the process of tomato planting, it will be very simple to prevent and cure them. We should choose high-quality, resistant varieties and high-quality and robust tomato seedlings, and plant them in land with good soil permeability, good drainage and fertile soil. After planting, the soil should be properly watered to keep the soil moist, but in case of continuous rainfall or rainstorm, timely drainage is needed to avoid stagnant water and lead to rotting roots. Fertilization needs to be carried out according to the growing period of tomato, the seedling stage is mainly nitrogen fertilizer to promote seedling growth, but also with the use of phosphorus and potassium fertilizer, and the use of nitrogen fertilizer should not be excessive. In order to avoid excessive nutrient concentration, it should be watered after fertilization. It is also important to note that in order to avoid soil consolidation, affect soil permeability and nutrient absorption, remember to loosen the soil after rainfall or watering. Finally, special chemicals are used to control different diseases and insect pests.
