How to prevent premature aging in tomatoes? A detailed guide to the latest methods
When growing tomatoes, premature aging is not unfamiliar. After premature aging appears in tomatoes, the most direct effect is on the tomato variety, and the nutrient absorption function of prematurely aging tomato plants drops greatly, and their yield also falls sharply. So how should premature aging in tomatoes be prevented? Let us take a look together.
1. Apply more organic fertilizer
Tomatoes have a relatively high fertilizer demand, and a large part of the reason for their premature aging is insufficient soil organic matter, which leads to soil compaction, poor permeability, weak plant absorption capacity, and thus premature aging. Therefore, while ensuring the three elements needed for tomato growth, appropriately increase the application of decomposed organic fertilizer, farmyard manure, and trace element fertilizer, which can enhance the soil organic matter content, improve soil permeability, and promote root growth and development. Especially during the seedling stage, flowering stage, and fruiting stage, multiple topdressings should be carried out, alternating chemical fertilizer and organic fertilizer to prevent premature aging. In the middle growth stage, foliar spraying can be used to maintain trace elements for the plants and avoid premature aging.
2. Strengthen water regulation
When the soil is too dry, the absorption capacity of the root system is weak, and the transport of nutrients is also hindered. Over time, the plants will show leaf wilting and yellowing due to lack of water and nutrients, and in severe cases will die from water shortage. In addition, after the rainy season, when there is standing water in the field or humidity is high, root rot is likely to occur, which can also lead to premature aging of the plants. Therefore, water must be well regulated, and the soil moisture content should be 60%-85%; it should not be too high. Water promptly during drought, and after rain take good drainage measures and loosen the soil to avoid soil compaction.
3. Pruning and removing side shoots
Removing side shoots is also one of the measures to prevent tomato damage. The timing of side-shoot removal should be noted; it should not be too early or too late. For those with weaker growth, side-shoot removal should be appropriately delayed. The first side-shoot removal is carried out when the side branches grow to 7-10 cm. After the first side-shoot removal, remove the lower old leaves and diseased leaves, which can reduce plant nutrient consumption and also prevent pests and diseases.
4. Regulate growth
During the flowering and fruiting stages, fruit should be retained appropriately, paying attention to the balance between vegetative growth and reproductive growth, so as to avoid retaining too much fruit, which can cause the plant's nutrient supply to be insufficient and lead to fruit drop. Early harvesting of fruit should be advocated to avoid premature aging of the plants.
