The causes and solutions of the latest uneven color conversion of tomatoes

Tomatoes, also known as tomatoes, are common vegetables in our lives. When they are not ripe, the skin is cyan and gradually turn red with growth, but some tomatoes are generally green and red after maturity. What causes its uneven color? the following pro-agricultural network brings you the reasons and solutions for the uneven color conversion of tomatoes.

1. Variety

There are many varieties of tomatoes, and each variety has different adaptability and quality to the environment, so it will show different external image in different environments, so when selecting planting varieties, we should combine the planting environment and choose good varieties suitable for the local environment.

2. Temperature

Tomato color change is due to lycopene, but too high and too low temperature will inhibit lycopene production, resulting in uneven tomato color conversion, forming irregular yellow and green spots on the fruit surface. This situation mainly occurs in early summer, the temperature difference between day and night is large, tomato growth does not adapt to the sudden change of temperature, resulting in uneven color, so we should pay attention to the temperature change when planting. If the greenhouse culture, the temperature during the day should not be higher than 30 degrees, at night to control the temperature of about 15 degrees.

3. Improper fertilization

Excessive application of nitrogen fertilizer will lead to exuberant growth and dense leaves, which will cause the leaves to seize nutrients and lead to the rapid increase of chlorophyll, thus inhibiting the formation of lycopene. Secondly, in the color conversion period, the demand for phosphorus and potassium fertilizer increases, the lack of phosphorus and potassium fertilizer will lead to the lack of nutrition and necrosis of the fruit, and the lack of nutrition in the color conversion process, the production of lycopene is less, so there will be cyan-red. We suggest that organic fertilizer should be used as the main fertilizer, with a balanced collocation of various elements.

4. Light and moisture

Light and water will affect plant photosynthesis and transpiration, too weak light, less lycopene production, poor color conversion; too strong light, direct radiation will burn the fruit, resulting in fruit discoloration. Too little watering, plant water loss, poor growth, too much watering, will cause stagnant water and lead to rotting roots.

The above are the reasons and solutions for the uneven color conversion of tomatoes brought by the pro-agricultural network, and the main cases of poor color conversion of tomatoes are the above, I hope they can help you.
