At present, eggplants grown in greenhouses often suffer from poor coloration of purple eggplants. The main manifestations are: the eggplant surface is not bright, the color is darker in front of the sun, the backlight surface is lighter in color, and the fruit surface is lavender, red-purple, and total to nearly green. Variegated, some of the fruit half color is not good, reducing the value of the goods. What is the cause of the poor coloration of eggplant fruit?
There are many factors that contribute to the poor coloration of round tomato, but there are three main points:
First, lack of light causes poor coloration of round tomato. Illumination weakly affects photosynthesis and delays fruit ripening and pigment transformation. In recent days, the haze weather was severe and the light was weakened, so that the fruit of the circle eggplant could not be adequately sunlit and coloring was poor. In addition, the fruits hidden under the leaves of the plants are also susceptible to poor coloration. This is mainly because the direct light irradiated on the eggplant fruits is blocked by the leaves. Therefore, the fruit can only be scattered light, and direct light irradiation cannot be obtained. As a result, fewer pigments are produced, and the color of the eggplant is also lighter, so it does not achieve a good product effect. To solve this problem, we should pay attention to reasonable sparse leaves to avoid shade shading affect fruit coloring.
Second, the high temperature caused a poor coloration of the round tomato. Temperature not only affects the differentiation of flower buds, but also affects the production and transportation of lycopene. The temperature in the shed is high, so it must be properly ventilated. This will not affect the formation of pigments, but also conducive to the accumulation of organic nutrients.
Third, malnutrition caused poor coloration of round tomato. If partial nitrogen fertilizer is applied, the soil will have poor air permeability and the fruit will be difficult to turn. In the late stage of the tomato eggplant, many sheds were yellowed in the leaves, and there were a lot of old leafy leaves. Many vegetable growers did not pay attention to late fertilization, there was an issue of unreasonable fertilization, there was a problem of insufficient potassium, and in the case of more fruit, plant production The nutrition can not meet the fruit growth needs, therefore, in the expansion period, should pay attention to the rational supplement fertilizer.
