Tomato planting techniques: how to prevent fruit cracking in summer and autumn?
How to prevent tomato from cracking in summer and autumn? Please introduce the prevention and treatment of tomato cracking symptoms in summer and autumn: when the tomato is ripe, radial cracks appear near the pedicel, which is radioactive cracking; concentric cracks appear in the shoulder of the fruit, which is concentric cracking. Many dehiscences are mixed dehiscence in which two kinds of dehiscence occur at the same time. In terms of cultivation types, there were more fruit cracking in tomato cultivated in open field in summer and in plastic film greenhouse in autumn. Prevention and control methods: the main method to prevent fruit cracking is to prevent the aging of pericarp and the sharp increase of soil water content. The aging of pericarp is caused by direct sunlight. The leaves of tomato after fruit setting can protect the fruit from the sun. If the sun is strong, you can also use a newspaper to make a paper tube over the inflorescence. If there are large leaves on the top of the fruit to cover the fruit, the disease prevention effect is better. The low content of calcium and boron in soil is also easy to cause pericarp aging. Calcium and potash fertilizers should be fully supplied and easily absorbed by plants. Under the condition of drying, the calcium absorption capacity of tomato plants becomes worse, and in the case of more fertilizer and potassium, the absorption of calcium will also be affected. Attention should be paid to the deep ploughing of the soil and the application of 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. It is also important to avoid direct contact between Rain Water and fruit noodles. Strengthen soil management so that the roots can expand to the deep.
