What causes premature aging in cucumbers?

Cucumbers are very common in daily life. They can not only be used in stir-fries, but also eaten raw, and can even be sliced and applied to the face, so they have many uses. However, many friends find during cultivation that in the later stages, cucumbers show signs of premature aging, which has a considerable impact on both the yield and quality of cucumbers. So what exactly causes premature aging in cucumbers? Today, the editor brings you the causes of premature aging in cucumbers. Let's take a look!

1. Temperature

Cucumbers like warmth. When the temperature exceeds the suitable growing temperature, it affects the growth of cucumbers. The most suitable temperature for cucumber growth is around 25 degrees. When the surrounding temperature keeps rising, especially in summer, and increases above 35 degrees, cucumbers are very prone to heat damage, sunscald and other problems, which reduce photosynthesis in cucumbers, preventing them from producing enough nutrients. Malnutrition then leads to premature aging.

2. Fertilizer and water

Improper use of fertilizer and water during cultivation. To prevent pests and diseases, some vegetable growers do not control the use of chemical fertilizer well in the soil, resulting in excessively high soil concentration, which affects root growth and development and, in severe cases, causes localized necrosis. Nutrient absorption capacity is reduced, harming plant growth. Before pulling up the vines, fertilizer and water application cannot be reduced or thinned out; otherwise, insufficient fertilizer and water will also lead to premature aging.

3. Roots

As the cucumber growing period gradually lengthens, the roots age faster and faster. When the temperature is too high, failing to control watering well will also cause some damage to the roots. Roots are the nutrient absorption channel for all crops. If root management is not done properly, it will have a very large impact on the growth and development of cucumbers. Root aging is unavoidable, but root injury can be reduced.

4. Management

Cucumber is a polycarpic crop that lives more than one year. In the later stage of growth, the yield of cucumbers decreases noticeably and the fruiting rate gradually declines, so vegetable growers relax management. The vines of the plants are not managed in time, causing excessive vegetative growth, so the lower leaves lack nutrients, begin to age, and consume a large amount of nutrients. In the later stage of cucumber growth, not enough nutrients are provided for its growth, which is also one of the causes of premature aging in cucumbers.

5. Diseases

After cucumbers grow into the later stage, their own resistance becomes weaker and weaker, and pathogens and parasites in the vegetable garden gradually increase. If prevention is not done well, various diseases will appear in the middle and later stages, such as anthracnose and gummy stem blight. Diseases have a relatively large impact on the stems and leaves of the plants, affect photosynthesis in cucumbers, lead to poor growth and development, and cause premature aging.

The above is a brief introduction to the causes of premature aging in cucumbers. In fact, improper use of pesticides during management can also cause some premature aging. Using too much pesticide and with too short an interval makes cucumbers very prone to pesticide damage, reduces the growth rate of cucumbers, and aggravates premature aging or even premature aging.
