Tomato green peel is related to many factors, such as temperature, light, moisture, fertilizer, etc., which will affect the growth of the plant, and then affect the color change of the fruit. So, what measures should be taken in production to promote the uniform coloring of tomatoes and reduce the green peel fruit?
Temperature control and shading promote uniform color transfer
Tomato coloring is mainly due to lycopene. There are many reasons for the coloring of tomatoes, according to the current environmental conditions, high temperature and strong light affect the accumulation of lycopene, which is the primary factor leading to the occurrence of tomato green peel fruit. Studies have shown that the optimal temperature for lycopene formation is 19 degrees Celsius ~ 24 degrees Celsius, and the greenhouse temperature below 14 degrees Celsius or higher than 32 degrees Celsius will affect the normal production of lycopene. When the temperature in the shed exceeds 35 degrees Celsius, lycopene is easily broken down, resulting in a yellowish color of the fruit.
In the current weather, the temperature in the shed can easily exceed 35 degrees Celsius, and at this time, the symptoms of yellowing of the fruit will appear. When tomato veraison, suitable light can promote its veraison, but too strong light is not only not conducive to veraison, but will destroy the pulp cells, thereby affecting the smooth process of veraison. Vegetable farmers are reminded that at present, the ventilation can be moderately increased according to the light conditions of the day, and the shed is covered with a shade net, which can be covered in time according to temperature and weather changes to avoid strong light and high temperature.
Rational fertilization balances nutrient supply
Fertilization is also an important factor affecting tomato coloration. When the fruit still appears green after ensuring that there is suitable light and temperature in the shed, it is necessary to consider whether the fertilization is reasonable. When the ratio of nitrogen, phosphorus and potassium is out of balance, especially when the nitrogen is high and potassium is low during the veraison period, the formation of lycopene will be affected, resulting in uneven veraison. Therefore, when the fruit enters the veraison stage, it is necessary to grasp the reasonable supply of nutrients such as nitrogen, phosphorus, potassium and medium and trace elements. For tomatoes with green skin, it is recommended that vegetable farmers supplement foliar fertilizer in time to adjust the nutrient status of the plant and promote fruit color change.
In addition, it is necessary to do a good job in the maintenance of the root system, and reasonably add biological fertilizer or rooting agent when watering, so as to improve the absorption capacity of the root system and reduce the impact of uneven fertilization in the early stage, so as to avoid the continued appearance of green skin in the later stage.
Tomatoes appear green skin to pay attention to these are introduced here, I hope it will be helpful to everyone. If you want to buy high-quality and high-yield tomato seeds, you can download the seed bank App, and the country's excellent tomato varieties are available for everyone to choose.
