Causes and control methods of tomato railings

Tomato is our common fruit and vegetable, its sour sweet taste is loved by many people, as its market demand increases, its planting area pressure is increasing year by year. Many people inevitably encounter many problems when planting, among which many growers are deeply harmed by tomato railings. So what's going on here? How to prevent it? Let's take a look at the causes and prevention methods of tomato railings.

Reason 1: improper watering, high soil moisture

Although tomatoes need a lot of water when they grow, they should not be watered too much each time. They can keep the soil moist. Too much watering leads to ponding, resulting in low ground temperature and poor soil permeability, thus causing rotten roots and railings.

Control methods: planting choose loose, good drainage soil, tomato growth period for water requirements are different, so scientific watering, watering can be frequent, but each time watering should not be too much. If you water too much or the soil moisture is high, you can increase the length of the tomato light, using the transpiration of the leaves to evaporate excess water.

Reason 2: Low temperature

The best temperature for tomato planting and growth is 20-30 degrees Celsius. If the temperature is lower than 13 degrees Celsius, its growth will slow down. If it is below 13 degrees Celsius for a long time, its growth and development will be poor. If it is lower than 6 degrees Celsius, the plant will be damaged by freezing, resulting in railing phenomenon.

Prevention and control methods: This phenomenon mainly occurs in the cold areas of the north, rarely occurs in the south, the temperature is too low can use greenhouse technology, continue to warm up, keep the temperature above 15 degrees can be.

Reason 3: Large temperature difference between day and night

Tomatoes grow at temperatures between 25-28 degrees during the day and 16-20 degrees at night. When the temperature difference between day and night is large, it will damage the roots and cause the plants to wither.

Control methods: This situation mainly occurs in the southern region in late spring and early summer, when the temperature is high during the day and low at night, which can easily lead to plant problems. Daytime temperature is too high can be shade, at night can be artificially heated or planted in greenhouses.

Reason 4: Disease

No disinfection of seeds and soil before planting, or long-term continuous cropping, resulting in the proliferation of bacteria in the soil, these bacteria easily lead to tomato bacterial wilt, blight and other diseases, these diseases will lead to plant railings.

Control method: Disinfect seeds and soil before planting, remove and burn diseased plants in time, sprinkle quicklime or plant ash on the soil to disinfect and sterilize, and apply chemicals for treatment.

The above is the introduction of the reasons and prevention methods for the tomato railings brought by the pro-agricultural network. I believe that everyone has some understanding of the reasons for the tomato railings. The pro-agricultural network also brings relevant prevention and control methods to everyone. I hope it helps.
