What about the latest cucumber retting?

Cucumber is a common melon vegetable in our daily life. Cucumber is relatively simple to grow, the yield is also relatively high, and the market demand is also very large. Therefore, now the planting area of cucumber is also relatively large, and when planting cucumber, there is often the phenomenon of cucumber retting root. Lead to a decline in cucumber yield, so what should be done about cucumber retting? The following editor will give you a brief introduction, let's have a look!

1. Retting root symptom

Cucumber root retting is a common physiological disease in cucumber growth period. After the retting phenomenon of cucumber roots, the roots will not grow new roots or adventitious roots. The color of the old root will be dark brown, which will cause the root to rot and eventually cause the plant to wilt. In serious cases, cucumbers will dry up in large numbers in the field. If you look at it only from the surface, it is similar to element deficiency. Root retting for a long time, then cucumber is also prone to root rot or quenching disease and other diseases, seriously affecting the growth of cucumber.

2. The reason of retting root

The root retting of cucumber is mainly caused by too low ground temperature or too much water. If the ground temperature is below 12 degrees for a long time and there are continuous rainy days or too much watering, then cucumber plants are extremely prone to wilting. However, if the wilting time is too long, it is easy to cause cucumber retting root. If the root retting occurs in the cucumber cotyledon stage, then the cotyledons will gradually scorch, and the retting roots during the real leaves will cause the scorching of the real leaves when they grow. In addition, if the ground temperature is lower than 6 degrees and the temperature is lower at night, it will cause the cucumber growth point to stop growing and eventually lead to the death of cucumber plants.

3. Prevention and control methods

Cucumber root retting is mainly based on prevention. First of all, before sowing seeds, soaking seeds with fine nail cream, manganese zinc and other agents can effectively reduce the phenomenon of cucumber root retting, but also improve the germination rate of cucumber seeds and enhance the cold resistance of cucumbers. When planting, ridging cultivation should be given priority to, and border cultivation should not be carried out, otherwise root retting is easy to occur. Then the soil should be leveled and should not be planted in low-lying and uneven areas, otherwise the soil is prone to stagnant water, resulting in retting roots and affecting the growth of cucumbers.

Then the management should be strengthened in the process of cultivation. Especially for the control of ground temperature, the ground temperature should not be too low, the soil water content should not be too large, and the ventilation volume and time should be controlled reasonably. If it is a low-temperature seedling, then it is best to use an electric hot line to increase the temperature, keeping the temperature at about 16 degrees, with a minimum of 12 degrees. After the cucumber seedlings are planted, a ploughing and hoeing should be carried out in order to increase the soil temperature and promote the root growth. After the root retting phenomenon of cucumber appears, the corresponding nutrient solution should be sprayed in time to alleviate the disease.

The above is a brief introduction to how to rett cucumber roots. That's all for today's introduction. This article is for reference only. I hope it can help you all.
