Coping techniques of Tomato Fruit cracking

First, strengthen the management of water and fertilizer. The root system of the plant grew well by ploughing the soil deeply and applying more organic fertilizer. When the temperature of tomato falls sharply after autumn, we should pay more attention to the management of soil moisture to avoid the rapid change of soil moisture. When cultivating in open field, we should water more at ordinary times to avoid drastic changes in soil moisture when it rains suddenly, and drain water in time after rain. Second, tomato fruit cracking is related to calcium and boron absorbed by plants. Insufficient supply of calcium and boron can cause fruit cracking, so it is necessary to supplement calcium and boron fertilizer in time, adjust the proportion of various nutrient elements in the soil, nitrogen fertilizer and potassium fertilizer should not be too much, otherwise it will affect the absorption of calcium by plants. Third, pay attention to environmental regulation. Pericarp aging is also easy to cause fruit cracking, avoiding direct sunlight on the shoulder is an effective measure to prevent pericarp aging, so when selecting inflorescences and pruning and binding vines, inflorescences should be arranged on the inside of the support and shaded by their own leaves. When picking the heart, leave two leaves on the top of the last ear to shade the ear. It is necessary to ventilate in time, reduce the air humidity and shorten the dew time of fruit surface during protected cultivation.
