Causes and Control of Tomato Hollow Fruit

Tomato fruit is generally large and round, with full juice inside, but recently it has been found that tomato fruit has a hollow fruit, the interior is hollow, there is irregular hollow, there is no juice or very little juice, and the appearance is also irregular shape, must not be round, this is what's going on, let's explore the reasons in order to find the appropriate prevention and control methods.

First, reasons

The placenta develops abnormally, the pericarp is too thin, and there are no seeds; or the pericarp grows rapidly and the pulp does not keep up with the growth to form a cavity; the pericarp grows too fast and the placenta can not keep up with the development of placenta, so it is deformed hollow; some early-maturing varieties themselves have relatively few petal chambers, so they are easy to be hollow; in the case of low temperature or high temperature and extreme weather during flowering, pollen will lose vitality, poor fertilization and produce malformed fruit. Improper use of growth regulators, stimulation and formation; improper management, irregular light, water and fertilizer.

II. Preventive measures

1. Selection of species

Choose the right variety, try not to choose the early-maturing variety, you can choose the middle-maturing variety or late-maturing variety, and you can choose the variety with more petal chamber, not the one with less petal chamber.

two。 Temperature

Sowing in the open field should choose the temperature suitable for emergence and growth before sowing, and the sowing time can be simply estimated, and then the fern will determine the sowing period, which indirectly determines that the flowering period after planting should not be too cold or too hot. Seedlings can be raised in small arched sheds and planted in greenhouses in early spring. It is good to have protected cultivation in late autumn and winter.

3. Use of growth regulators

In order to protect flowers and fruits, it is necessary to use some growth regulators, such as dipping flowers with 2pyr4-dichlorophenoxyacetic acid, although the flower preservation effect is good, but the pericarp growth can not catch up with placental growth. Therefore, it is best to use other spray fruit protection agents, such as Tomato Ling fruit setting effect is good.

4. Strengthen management

In the period of rapid growth and expansion, the light is not good, the nutrition can not keep up, and then the nutrition of the plant fruit is not balanced, and the fruit is easy to be stored without nutrition and hole. Lack of water and fertilizer, nutrition supply, will be empty, can be greenhouse planting automatically adjust light, fertilization and water supply should be based on the stage supply.

There are many reasons for tomato holes, and there are three types of holes that travel most frequently. Probably summed up a few points, there may be other reasons. Some other reasons may be found during production and planting. We can sum up experience and aim at prevention.
