How to Prevent Fruit Cracking in Tomatoes in Summer and Autumn? Please Introduce Control Methods
Symptoms of Tomato Fruit Cracking in Summer and Autumn: When tomatoes ripen, radial cracks appear near the stem end of the fruit, which is radial cracking; concentric cracks appear on the shoulder of the fruit, which is concentric cracking. Many cases of fruit cracking are of a mixed type in which both cracking phenomena appear at the same time. In terms of cultivation type, fruit cracking occurs more often in tomatoes grown in open fields in summer and in tomatoes grown in plastic film greenhouses in autumn.
Control Methods: The main methods for preventing fruit cracking are preventing the aging of the fruit skin and avoiding a sharp increase in soil moisture content.
Aging of the fruit skin is caused by direct sunlight hitting the skin. The leaves of the tomato after fruit set can provide shade and protection for the fruit. If the sunlight is very strong, a paper tube made from newspaper can also be placed over the flower cluster. If a large leaf can cover the fruit from above, the disease-prevention effect is better.
Low calcium and boron content in the soil also easily causes aging of the fruit skin. Calcium fertilizer and potassium fertilizer should be supplied adequately, and the plants should be able to absorb them well. Under dry conditions, the ability of tomato plants to absorb calcium becomes poorer, and under conditions of excessive fertilizer and potassium, calcium absorption is also affected. Attention should be paid to deep plowing of the soil and applying an appropriate amount of base fertilizer, so that the roots can grow fully and absorb nutrients and water well.
Attention should be paid to rational irrigation to avoid a sharp increase in soil moisture caused by rain after drought. Avoiding direct contact between rainwater and the fruit surface is also very important. Strengthen soil management so that the roots can extend deeper.
