Tomatoes do not change color
A vegetable in Shouguang City, Shandong Province: How do tomatoes do not change color?
Wang Yanyi A: The main reasons for this phenomenon: First, high temperature, strong light, affecting the color change of tomato fruit. During this time, temperature and light conditions are the main factors that restrict the color change of tomatoes. Increase the amount of ventilation, cover the sunshade net outside the shed, cover it in time according to temperature and weather changes, avoid glare and high temperature. Second, insufficient supply of nutrients. The late management can't keep up, the soil is too dry, and the nutrient supply is insufficient, which is the second reason that affects the color change of tomatoes. Reasonable supply of fertilizer and water, strengthen the maintenance of the middle and upper leaves to ensure the normal supply of nutrients, can ensure the formation of tomato lycopene, and ensure normal color change.
