The causes of the latest cucumber glue flow and its control methods

Cucumber is a common vegetable in daily life, which is widely planted, but the phenomenon of cucumber stem gum flow often occurs in the process of cucumber planting, which will cause the stem vines to wither gradually until the water temperature. After guar gum flow, the commodity value is low, and even deformities or soft rot appear, resulting in the loss of edible value of cucumber, light yield reduction, heavy harvest, which does great harm to the yield. So what is the cause of cucumber gumming? Come and have a look with the editor.

I. bacterial diseases

Bacterial canker and edge blight of cucumber are the main bacterial diseases that often cause bacterial pus in melon strips. White blossoming bacterial pus will appear on melon strips, which is not easy to flow, the wound where pus is unknown, the color is generally white, and it will also cause melon strips to rot and give off a bad smell.

Prevention and treatment: bacterial agents can be sprayed on the leaves, and at the same time, the wound of the plant should be prevented, otherwise it is easy to be infected with bacterial diseases. In order to reduce the indoor temperature in greenhouse cultivation, rice husks can be laid in continuous overcast and rainy days, reduce humidity and increase carbon dioxide content, which has an obvious effect on increasing yield.

II. Fungal diseases

There are many fungal diseases causing cucumber gum flow, such as gray mold, Sclerotinia sclerotiorum, scab, vine blight, brown spot and so on.

Prevention and control methods: the prevention and control methods of these diseases should be based on the characteristics of their diseases. First of all, preventive measures should be taken to reduce the humidity in the field, increase ventilation, and try not to leave wounds during agricultural operations. Fungicides can be applied to prevent fungal invasion after picking leaves and melons. When the disease occurs, it is necessary to identify the symptoms of various diseases, and then prescribe the right medicine.

III. Physiological diseases

The glue flow of melon strips caused by physiological diseases generally appears small cracks on the surface of melon strips, and then appears glue flow, the main reasons are: first, watering suddenly dry and wet, melon strips grow slowly during the harvest period. Can not be watered during long-term drought, otherwise it will cause melon strip skin cracks and glue flow; second, poor ventilation, sudden ventilation, will also cause cucumber skin wrinkling and glue flow; third, improper use of hormones, such as excessive anther concentration or application of a large amount of hormone fertilizer, will lead to cucumber rapid growth in a short period of time, resulting in cracks in the epidermis and glue flow.

Prevention and control methods: reasonable watering and ventilation, when the necessary conditions for the normal growth of cucumbers, when using hormones, we should pay attention to weather changes, cloudy days to reduce the concentration, but also pay attention to the types of hormones, cucumbers have different responses to hormones, improper use of drugs may cause serious glue flow.

The above is the introduction of cucumber glue flow causes and control methods, hope to help you, want to know more related knowledge, please pay attention to us.
