What are the latest causes of 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. They have many uses. However, many friends will find during cultivation that in the later stage, cucumbers show signs of premature aging. Premature aging has a considerable impact on both the yield and quality of cucumbers. So what exactly causes premature aging in cucumbers? Today, the editor has brought 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 will affect the growth of cucumbers. The most suitable temperature for cucumber growth is around 25°C. When the surrounding temperature keeps rising, especially in summer, and the temperature increases to above 35°C, cucumbers are very prone to heat damage, sunscald and other problems, which reduce photosynthesis in cucumbers, making them unable to produce enough nutrients. Malnutrition leads to premature aging.
2. Fertilizer and water
Improper use of fertilizer and water during cultivation. Some vegetable growers, in order to prevent and control pests and diseases, do not control the use of chemical fertilizer well in the soil, resulting in excessively high soil concentration, which affects the growth and development of the roots and, in severe cases, causes localized necrosis. The nutrient absorption capacity decreases, harming the growth of the plant. If fertilizer and water are not reduced before pulling up the vines, otherwise insufficient fertilizer and water will also lead to premature aging.
3. Roots
As the growth time of cucumbers gradually lengthens, the aging speed of the roots also becomes faster and faster. When the temperature is too high, failing to control watering well will also cause certain damage to the roots. The roots are the nutrient absorption channel of all crops. If root management is not in place, it will have a very large impact on the growth and development of cucumbers. Root aging is unavoidable, but the situation of root injury can be reduced.
4. Management
Cucumbers are a perennial crop. In the later stage of growth, the yield of cucumbers decreases significantly, 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, which leaves the lower leaves with insufficient nutrients, and they begin to age and consume a large amount of nutrients. In the later stage of cucumber growth, not providing enough nutrients for their growth is also one of the causes of premature aging in cucumbers.
5. Diseases
After cucumbers grow to the later stage, their own resistance becomes weaker and weaker, and the pathogens and parasites in the vegetable garden gradually increase. If prevention is not in place, various diseases will appear in the middle and late stages, such as anthracnose, gummy stem blight and so on. Diseases will have a relatively large impact on the stems and leaves of the plants, affecting the photosynthesis of cucumbers, leading to poor growth and development and causing 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 a certain degree of premature aging. Using too much pesticide, or with too short a time interval, makes cucumbers very prone to pesticide damage, reduces the growth speed of cucumbers, and aggravates premature aging or even causes premature aging.
