The latest ways to prevent premature senescence of tomatoes

In the cultivation of tomato is no stranger to premature senility, after the emergence of premature senility of tomato, the most intuitive is to affect the variety of tomato, and premature senescence of tomato plant nutrient absorption function greatly decreased, its yield will also decline in a straight line. So how to prevent the premature senescence of tomatoes? Let's take a look.

1. Increase the application of organic fertilizer

Tomato needs a large amount of fertilizer, and a large part of its premature senescence is due to the lack of soil organic matter, resulting in soil consolidation, poor permeability and weak absorption of plants, resulting in premature senescence. Therefore, under the three elements needed to ensure the growth of tomato, the appropriate application of rotten organic fertilizer, farm fertilizer and trace element fertilizer can enhance the content of soil organic matter, improve soil permeability and promote root growth and development. Especially in the seedling stage, flowering stage and fruit stage, topdressing should be carried out many times, and chemical fertilizer and organic fertilizer should be used alternately to prevent premature senility. In the middle stage of growth, foliar fertilizer spraying can be used to keep trace elements for the plant and avoid premature senescence.

2. Strengthen water regulation and control.

When the soil is too dry, the absorption of the root system is weak, and the transport of nutrients will be hindered. For a long time, the plant will appear leaf withering and yellowing due to lack of water, and in serious cases, it will die due to lack of water. In addition, after the rainy season, when there is stagnant water or high humidity in the field, it is easy to cause root rot and plant premature senescence. Therefore, the water content should be well regulated, and the soil water content should not be too high. It should be watered in time during drought, the best drainage measures should be taken after rain, and the soil should be loosened to avoid soil consolidation.

3. Pruning and branching

Forking is also one of the measures to prevent tomato from suffering. attention should be paid to the time of forking, not too early or too late, for those with weak growth, it is appropriate to branch late and grow to 7-10 cm in the side branches for the first time. Remove the lower old leaves and diseased leaves after the first forking, which can reduce plant nutrient consumption and prevent diseases and insect pests.

4. Regulating growth

It is necessary to keep fruit properly in flowering and fruiting stage, and pay attention to the balance of vegetative growth and reproductive growth, so as to avoid the lack of plant nutrition supply and fruit drop phenomenon. Early fruit harvest should be advocated to avoid plant premature senescence.
