Tomatoes, commonly known as "tomatoes," are one of the common vegetable varieties on people's daily dining tables. They are juicy, sweet and sour, and rich in nutritional value. However, many growers often encounter various problems during the cultivation of tomatoes. Let's learn together.
Reasons for Tomato Fruit Drop
-
High Temperature
When the temperature inside the greenhouse is high, especially when the night temperature is high, tomatoes tend to grow rapidly, with rapid stem elongation, making it difficult for them to set fruit.
-
Inappropriate Nutrient Supply
If tomatoes are supplied with too much fertilizer, especially nitrogen-rich fertilizer, the plants will absorb excessive nutrients, leading to excessive growth.
-
Hormonal Effects
Many farmers now use quick-acting foliar fertilizers, which may contain growth-promoting hormones. Excessive use of these fertilizers can accelerate the growth of tomatoes, leading to nutrient imbalances and excessive elongation of the plants.
Prevention Methods for Tomato Fruit Drop
-
Temperature Regulation
The temperature inside the greenhouse should not be too high. It is best to keep it below 30 degrees Celsius during the day and between 12-18 degrees Celsius at night. If it is a sunny day, shading or spraying water at noon can be done to control excessive growth.
-
Application of Growth Regulators
Foliar spray with growth regulators can control the growth of tomatoes, making the stems thicker and stronger. The dosage of growth regulators should not be too high, and spraying is best done on sunny days.
-
Leaf Removal
Remove some vigorously growing leaves to adjust the growth of tomatoes.
-
Supplementing Boron and Calcium
When tomatoes grow too fast or when the weather is too hot, spraying some boron or calcium micronutrients can be beneficial.
-
Proper Pollination
Use point pollination wisely. If the temperature is high, increase the proportion of water to promote flower and fruit setting.
In conclusion, the above are the reasons and prevention methods for tomato fruit drop. Tomato growers can refer to their own actual situation and take preventive measures in advance.
Tomato Fruit Drop FAQ
What are the main reasons for tomato fruit drop?
The main reasons for tomato fruit drop include high temperatures, inappropriate nutrient supply, and hormonal effects.
How can I regulate the temperature to prevent tomato fruit drop?
To prevent tomato fruit drop due to high temperatures, it is essential to keep the temperature inside the greenhouse below 30 degrees Celsius during the day and between 12-18 degrees Celsius at night. On sunny days, shading or spraying water can help control excessive growth.
What growth regulators can be used to prevent tomato fruit drop?
Using growth regulators for foliar spray can help control the growth of tomatoes, making the stems thicker and stronger. It's crucial to ensure that the dosage of growth regulators is not too high, and spraying is best done on sunny days.
