First of all, according to the different positions of the head, reasonable sparse leaves. Because the light is sufficient now, the tomatoes generally do not turn bad due to lack of light, on the contrary, too strong light will also affect the coloring of tomatoes, so the farmers can not be excessive when the leaves. When cherry tomatoes are just beginning to be harvested, because the upper leaves of the plants are dense and shading is better, the vegetable farmer can remove the leaves of the fruit of the 1~2 ear near the lowermost part of the plant to promote fruit color conversion, but for the plants above the 3 ear fruit For the leaves, the tomatoes on the ear should be completely removed and then the leaves on the upper part of the corresponding ears should be removed. Alternatively, one-third of the leaves should be cut off by cutting the leaves to ensure the ventilation and light transmission of the fruits. The scattered light shines on the tomato fruit to promote fruit coloration, while avoiding direct sunlight on the surface of the fruit, producing sunburn fruit. In addition to promoting fruit coloration, it can also retain more leaves to ensure the organic nutrients produced by the leaves and promote fruit enlargement.
Second, the top of the plant should be left with collateral shading. The closer to the point of tomato growth, the greater the chance of the tomato's fruit to see the light, because the skin of the cherry tomatoes is thin, and after entering the summer, once the strong light is shining on the surface of the ripening fruit, the sunburst fruit can easily be produced, so the vegetable farmers are sparse. In addition to lateral branches, in addition to taking 2 to 3 leaves in the upper part of each trunk, we must also pay attention to leaving two side branches. When the side branches grow to about 3 leaves, we will pick the heart again to increase the shading area of ​​the fruits and prevent them from being produced. Sunburn fruit.
In addition, the vegetable farmers can also use the shading nets to shave the fruits when the temperature is high at noon and the sunlight is strong, and it can also effectively prevent the generation of sunburn fruit.
