Ways to Prevent the Malformation and Empty Fruits of Tomato

It is easy for tomatoes cultivation in warm house to have malformed fruits and hollow fruits, which can decline the quality and yield of tomato.
1. Symptom
Deformed fruits: irregular enlargement of fruits, and there is a large piece of scar in the skin of fruits.
Empty fruits: there are hollowness between the peel and the pulp and the appearance of fruit is a multi-vector form.
2. Etiology
1, Deformed fruits: mismanagement in the seedling period is the main cause. breeding in the weak light and low temperature (less than 10 ℃) will lead to deformed fruits. Drought will inhibit the normal growth of seedlings in the early state, and lead to scared fruit and exposed fruit.
2, Empty fruits: It is the improper management in the fructification period. (1) the impact of fruit hormone. (2) a longer period of low temperature and poor light will reduce the photosynthetic products, and the demand exceeds the supply of the nutrient delivery to the fruit. (3) the amount of fertilizer and water is insufficient and the growth of fruits is inhibited.
3. control methods
1, Deformed fruits: (1) maintain temperature 20-25 ℃ in the daytime, and 13-17 ℃ in the night, and prevent the emergence of low temperature below 10 ℃, which will cause abnormal flowers. (2) Maintain a suitable temperature and moisture, plus spray 85% chemical powder to control the abnormal growth of the seedlings. (3) Remove timely the deformed fruits to decline the nutrition consumption and promote the other fruits to grow.
2, Empty fruits: (1) rationally use fruit hormone. Especially in the early spring, it is necessary to spray after the flowers bloom. Also pay attention to the management of water and fertilizer to promote the normal growth of fruits and remove the hollow fruits to reduce the nutrition consumption. (Reproduced)
