Teachers, what is the white skin of tomatoes?

The fruit of the tomato became pale, which proved that it was almost discolored. The fruit color is the best when the temperature is 65438 08℃ ~ 26℃. When the daily temperature is higher than 32℃, the fruit grows and matures quickly, and the formation of lycopene is blocked, which affects the coloring. If the temperature is too low, it will also seriously affect the fruit coloring. At present, if the shed is protected,

If the temperature effect is not good, when the greenhouse temperature is lower than 12℃, the green decomposition of leaves will be delayed or slowed down, and the formation of lycopene will be hindered, which will seriously affect the fruit coloring.

Especially in the stage of turning red at fruiting stage, if excessive nitrogen fertilizer is applied, chlorophyll will increase greatly, which will inhibit the formation of lycopene and carotene, thus affecting fruit coloring.

Potassium dihydrogen phosphate and calcium magnesium nitrate can be sprayed to promote tomato coloring.
