What are the latest methods to prevent and control tomato fruit cracking
Tomato is a common fruit and vegetable variety in our daily life; it can be eaten as a fruit and also used as a vegetable. When we grow tomatoes, fruit cracking generally occurs during the young fruit stage and near maturity, which seriously affects the quality of tomatoes and thereby reduces the economic benefits of vegetable growers. So what causes tomato fruit cracking? And how should it be prevented and controlled? Now let me give you a detailed introduction.
1. Causes of tomato fruit cracking
There are many causes of tomato fruit cracking. For example, the varietal characteristics of tomatoes: some varieties have thinner skin, so the fruit cracking is more severe; secondly, the timing of ventilation is wrong, and ventilation is not carried out reasonably; another cause is improper fertilizer and water management, which can also cause tomato fruit cracking; if tomatoes are not harvested in time after ripening, fruit cracking can also occur later; finally, if the concentration of the pesticide sprayed is too high or the spraying time is unreasonable, it can also cause fruit cracking. These are the most common causes of tomato fruit cracking.
2. Symptoms of fruit cracking
When the causes of tomato fruit cracking differ, the symptoms shown by some tomatoes also differ. For example, there are two phenomena: top cracking and pattern cracking. Top cracking is when the fruit's navel area and the surrounding skin crack, sometimes even splitting into many pieces; pattern cracking is divided into several symptoms such as radial pattern cracking, concentric circle pattern cracking, stripe pattern cracking, and tomato transverse cracking, and the severity of cracking among them also varies, requiring case-by-case analysis.
3. Prevention and control methods
There are many methods to prevent and control tomato fruit cracking, but they are all determined according to specific situations. First, we can choose tomato varieties resistant to fruit cracking; secondly, reasonably control water and fertilizer, and supply fertilizer and water scientifically according to the tomato's water and fertilizer requirements; another point is scientific fertilization, reducing the use of nitrogen fertilizer and potassium fertilizer, and ensuring the supply of calcium and boron elements; finally, plant growth regulators can be used, and sprayed at a reasonably prepared concentration, which can also achieve a preventive effect.
4. Planting precautions
In the process of growing tomatoes, we should generally pay attention to these points, which can also provide good protection against tomato fruit cracking. First is the control of the growing environment, reasonably controlling light intensity; secondly, reasonably control the temperature of the planting site; another point is the reasonable use of pesticides, and paying attention to the time, temperature, concentration, etc. of pesticide spraying; finally, pruning and removing side shoots should be moderate to avoid excessive concentration of nutrients, which can cause fruit cracking.
The above is all the content I want to share with you today, and I hope it can help you. Of course, in the process of growing tomatoes, preventing and controlling fruit cracking must be done step by step. As long as every step is done properly, fruit cracking will basically not occur.
