Tomatoes are our common fruits and vegetables. Their sweet and sour taste is loved by many people. As its market demand increases, its planting area is increasing year by year. Many people will inevitably encounter many problems when planting, and many of them are deeply affected by tomato railings. So what is this about? How to prevent it? Let's take a look at the reasons and prevention methods of tomato railings.
Reason one: improper watering, high soil moisture, although tomatoes need a lot of water during growth, but each time watering should not be too much, keep the soil moist, too much watering causes water accumulation, resulting in low ground temperature, soil pass Poor permeability, causing rotten roots and railings.
Control method: When planting, choose loose and well-drained soil. The tomato needs different water requirements during each growth period, so it should be scientifically watered and watered, but it should not be too much. If there is too much watering or high soil moisture, it can increase the length of light of the tomatoes and use the transpiration of the leaves to evaporate excess water.
Reason 2: The temperature is low. The optimal temperature for tomato planting growth is 20-30 degrees. When the temperature is lower than 13 degrees, its growth will be slower. If it is at a temperature below 13 degrees for a long time, the growth and development will be poor. Below 6 degrees, the plant will freeze. Damage, resulting in railing.
Control methods: This phenomenon mainly occurs in the cold regions of the north, and rarely occurs in the south. If the temperature is too low, the greenhouse technology can be used to continue to heat up and keep the temperature above 15 degrees.
Reason three: the temperature difference between day and night, large tomatoes during the day, the temperature is between 25-28 degrees, at night between 16-20 degrees, when the temperature difference between day and night is large, it will damage the roots, causing the plants to wilted railings.
Control method: This situation mainly occurs in the southern part of the spring and early summer. At this time, the temperature is high during the day and the temperature is low at night, which is likely to cause problems in the plant. When the temperature is too high during the day, it can be shaded, and at night it can be artificially heated or planted in a greenhouse.
Reason 4: The disease is not disinfected before seeding and soiling, or long-term heavy sputum, leading to the proliferation of pathogens in the soil. These bacteria are easy to cause diseases such as bacterial wilt and blight of tomatoes, and these diseases will lead to plant railing.
Control method: Disinfect the seeds and soil before planting, and find that the diseased plants are removed and burned in time, and lime or grass ash is sprayed on the soil to disinfect and sterilize, and the medicament is used for treatment.

Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
