How to prevent early aging in tomatoes? These key measures must be done well
When growing tomatoes, early aging is not unfamiliar. After tomatoes show early aging, the most direct effect is on the tomato variety, and the ability of early-aged tomato plants to absorb nutrients drops greatly, and their yield also drops sharply. So how should tomato early aging be prevented? Let's take a look together.
1. Increase the application of organic fertilizer
Tomatoes have a relatively high fertilizer demand. A large part of the reason for their early aging is insufficient soil organic matter, which leads to soil compaction, poor permeability, and weak plant absorption capacity, resulting in early 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's organic matter content, improve soil permeability, and promote root growth and development. Especially at the seedling stage, flowering stage, and fruiting stage, topdressing should be carried out multiple times, and chemical fertilizer and organic fertilizer should be used alternately to prevent early aging. In the middle growth stage, foliar spraying can be used to maintain trace elements for the plants and avoid early 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, they will die from lack of water. In addition, after the rainy season, when there is standing water in the field or the humidity is high, it is easy to cause root rot, which can also lead to early aging of the plants. Therefore, water must be well regulated. The soil moisture content should be 60%-85%, and it should not be too high. Water timely during drought, and take good drainage measures after rain, and loosen the soil to avoid soil compaction.
3. Pruning and pinching
Pinching is also one of the measures to prevent tomato damage. The timing of pinching should be noted; it should not be too early or too late. For those with weaker growth, pinching should be appropriately delayed. The first pinching should be done when the side branches grow to 7-10 cm. After the first pinching, remove the lower old leaves and diseased leaves. This 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, and attention should be paid to balancing vegetative growth and reproductive growth, so as to avoid excessive fruit retention causing the plant's nutrient supply to be insufficient and leading to fruit drop. Early fruit harvesting should be advocated to avoid early aging of the plants.
