How to prevent and cure tomato flower face disease? learn these three tricks not to make a face.

Tomato mosaic disease will affect the quality and yield of tomatoes, but many farmers are not clear about how to prevent and grow tomatoes. Mosaic disease is generally due to lack of water and nutrients, unreasonable temperature, light and humidity, red and yellow spots on the fruit, or brown or green spots on the fruit, and the interior of the fruit is also different from that of the normal fruit. Therefore, it is necessary to grasp the correct prevention and prevention methods to avoid tomato faces.

How to prevent tomato flower face disease

1. Fertilization must be reasonable.

Tomato mosaic disease may be due to excessive vegetative growth, resulting in the increase of tomato chlorophyll, inhibit the formation of lycopene, and then the emergence of a large number of macula, and then the formation of "flower face".

When boron and potassium are deficient and nutrient delivery is not smooth, the tomato will turn brown due to lack of nutrition, so it needs to be applied base fertilizer and reasonably matched with various trace elements, which can strengthen the photosynthesis of the plant and make the tomato grow healthily.

two。 Keep the right temperature

The temperature of tomato fruit noodles should not exceed 32 degrees, because this is not conducive to the synthesis of lycopene in the fruit, which will make the pericarp appear residual green or brown. When the temperature is below 8 degrees, lycopene will be destroyed, and this damage can not be reversed. Finally lead to tomato "flower face", so it is necessary to maintain a temperature of about 25-30 degrees, at night the temperature can be maintained at about 13-17 degrees, and adjust the moisture. Tomatoes can grow well.

3. Keep plenty of water and light

Water and light will affect the transpiration of tomato, so it is necessary to keep sufficient light, be careful not to let direct sunlight, and do not let the soil be too dry, tomato root nutrient supply is insufficient, so can maintain scattered photosynthetic water, pay attention to root cultivation, tomato fruit can grow well.

When farmers encounter mosaic disease when planting tomatoes, they should pay attention to analyzing the causes to see whether it is caused by lack of fertilizer, or by lack of trace elements, or by low temperature, so that corresponding ways need to be taken to avoid it. Pay attention to watering and fertilization, keep the temperature appropriate, so that tomatoes do not appear flower face.
