First, strengthen water and fertilizer management. Deeply pour into the ground, increase organic fertilizer, so that the plant roots grow well. After the fall of tomatoes, when the temperature drops sharply, the soil humidity management must be paid more attention to avoid excessive changes in humidity. In open field cultivation, watering is usually required to avoid sudden changes in soil moisture when rain suddenly occurs, and timely drainage after rain.
Second, tomato cracking is related to calcium and boron absorbed by plants. Insufficient supply of calcium and boron can cause cracking, so it is necessary to supplement calcium fertilizer and boron fertilizer in time to adjust the proportion of various nutrients 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. Peel aging is also easy to cause cracking, avoid direct sunlight is the effective measure to prevent skin aging, so in the election of inflorescence and pruning vines, the inflorescence should be arranged on the inside of the bracket, by its own leaves shading. When picking the heart, leave two leaves on top of the last ear to shave the ear. Ventilation during facility cultivation should be timely, reduce air humidity, and shorten fruit surface condensation time.
