What to do with tomato fruit "ribs"

Every year in the autumn and winter seasons, vegetable farmers always report that the tomato fruits in the shed are "ribbed", which are hollow fruits, with low yield and poor quality. The occurrence of this situation has a lot to do with the weather and improper cultivation management.

cause

There are many reasons for tomato hollow fruit, such as excessive use of nitrogen fertilizer, continuous rainy weather, insufficient light, reduced photosynthesis, insufficient nutrients inside the tomato fruit, easy to produce hollow fruit; during the flowering period of the tomato, if the temperature in the shed exceeds 36 The temperature lasts for a long time, pollen is poorly fertilized, and the cells of the pulp tissue during fruit development are not coordinated with the growth rate of the fruit, which will form hollow fruits. In addition, if the supply of fertilizer and water is insufficient during the tomato fruit setting period, the concentration of anthers is unreasonable, which may easily lead to hollowness. The formation of fruit.

Precaution

Control the temperature difference between day and night: in early winter, the temperature difference between day and night is widened, but the temperature is not low in the deep winter. The light is strong around noon in fine weather, and the temperature in the shed is high. Vegetable farmers should pay attention to maintaining the temperature difference between day and night to avoid high night temperature and causing plants to appear Lengthen, reduce the flow of nutrients to the fruit, and then produce hollow fruit. After entering the fruitful period, the night temperature should be controlled at about 15°C, which can be adjusted by adjusting the air release time and the release time of the insulation quilt.

Reasonable use of fertilizer: After the tomato enters the flowering and fruit-setting period, it is necessary to appropriately control the amount of nitrogen fertilizer and increase the amount of potassium fertilizer. Potassium can promote the synthesis and transportation of sugar, and promote the transportation of nutrients to the fruit, which can not only increase the weight of the fruit, but also make the fruit taste Good, bright color, reduce the occurrence of hollow fruit. In addition, proper boron and calcium fertilizer should be added to the leaves during the flowering and fruit setting period of the tomato to increase the fruit setting rate.

Don’t be greedy for more fruits: If there are more fruits in the first few panicles, it will easily lead to insufficient nutrients in the next panicle fruits and more hollow fruits. Therefore, in terms of fruit retention, it is recommended that vegetable farmers keep the fruit reasonably according to the growth of the plants in their shed and the nutrient supply. Generally, there are 2-3 first ear fruits of tomato, and 3-4 per ear afterwards; in the early stage, there are appropriate few to cultivate strong trees; the weak ones are appropriate to leave less, promote plant rejuvenation, and ensure the quality and yield of fruits in the middle and late stages. Of course, if the tomato is growing more vigorously, you can also take early fruit retention to control the tree, but you must grasp the degree and immediately remove it after reaching the goal. Avoid too much fruit, and the probability of hollow fruit will greatly increase, which will affect the yield. And benefits.
