What is the cause of pot-bellied cucumber? How to prevent it?

Cucumber is a common vegetable, which tastes refreshing and light, has high nutritional value, and is deeply loved by consumers. In the process of planting cucumbers, the prices of good and fresh cucumbers are higher. However, there will still be some reasons for the phenomenon of big belly of cucumbers, so farmers can not get a good price. Let's take a look at the cause of pot-bellied cucumbers.

What is the cause of pot-bellied cucumbers?

The main feature of the big-bellied melon is that the head of the melon strip appears obviously thick, shaped like a big belly. Most of these melons are caused by incomplete pollination and fertilization. If it is not fertilized unisexual melon, it is due to weak plant growth, malnutrition, especially caused by potassium deficiency. Sometimes in the process of melon strip growth, there is a lack of water in the early and later stages, and a big-bellied melon can be formed in the middle period.

Cucumber female flower fertilization is not complete, only produce seeds at the top of the melon, so that nutrients accumulate to the apex, resulting in the apical pulp tissue is particularly hypertrophic, showing a big belly melon head.

Plants are deficient in potassium and oversupplied with nitrogen fertilizer, which will produce melons.

Cucumber is short of water in the early stage of growth, but a large amount of water supply in the later stage will produce big-bellied melon. This is because water has a strong effect on the elongation or hypertrophy of cells. when water is scarce, cells grow slowly, while when there is a large amount of water supply, cells develop rapidly.

Second, how to prevent the phenomenon of pot-bellied cucumber?

1. Create suitable conditions to promote flowering and pollination, or use suitable anthers.

two。 Appropriate application of plant ash, potassium nitrate and other potassium fertilizer, foliar spraying potassium dihydrogen phosphate and other potassium-containing foliar fertilizer.

3. Balance the water supply in the whole growth cycle of cucumber, keep the soil dry and wet, and avoid sudden flood irrigation after excessive drought.

Third, how to improve cucumber belly melon?

First of all, create good conditions for flowering and pollination. Cucumber female flower fertilization is not complete, only produce seeds at the top of the melon, so that nutrients accumulate to the apex, resulting in the apical pulp tissue is particularly hypertrophic, showing a big belly melon head. First, the male flowers are picked and the petals are removed. Then gently rub the stigma of the female flower with the style to make the pollen fall on the stigma. In order to increase the chances of success, several male flowers can be used to pollinate a female flower. You can also dip a cotton swab with male pollen and brush it on the female stigma.

Secondly, balanced fertilization should be applied during the flowering and fruiting period. When the nutrients needed and consumed by flowering and fruit setting and fruit growth and development were applied in time, the ratio of nitrogen, phosphorus and potassium was 5:2:6, and a second high quality foliar fertilizer was sprayed every 10 to 15 days.

Once again timely and appropriate amount of watering, with water and fertilizer, promote root development, prevent soil from being too dry and wet, and ensure balanced water supply; balanced water supply throughout the growing period, keep the soil wet, and avoid excessive drought and lack of water or flood irrigation.

Finally, the flowers and fruits were thinned properly, and the melons were left after the plant growth was restored. When the female flower blossoms upward, it blossoms abnormally and should be removed. Normal female flowers open obliquely downward, with large, bright yellow flowers.
