Causes of premature senescence of cucumber

Cucumber is very common in life, not only can be fried, but also can be eaten raw, and even can be cut into pieces for application, the role is very many. However, many friends will find that in the late stage of planting, cucumber will appear premature aging phenomenon, premature aging will have a great impact on the yield and quality of cucumber. So what exactly causes cucumber premature aging? Today's small series brings you the reasons for premature cucumber aging. Let's take a look together!

1. Temperature

Cucumber thermophilous, temperature exceeds the appropriate growth temperature, will affect the growth of cucumber. The most suitable temperature for cucumber growth is around 25 degrees, and when the ambient temperature increases continuously, especially in summer, the temperature increases to more than 35 degrees. Cucumber is prone to heat damage, sunburn and other problems, so that the photosynthesis of cucumber is reduced, unable to produce enough nutrients, malnutrition leads to premature aging.

2, fertilizer water

Improper use of fertilizer and water during planting. Some vegetable farmers did not control the use of chemical fertilizers in the soil to prevent diseases and insect pests, resulting in too high soil concentration, affecting the growth and development of roots, and local necrosis in severe cases. Nutrient absorption capacity is reduced, causing harm to the growth of plants. Before pulling seedlings, fertilizer and water should not be reduced, otherwise insufficient fertilizer and water will also lead to premature aging.

3. Roots

Cucumber growth time gradually lengthened, the aging speed of the roots is also faster and faster, when the temperature is too high, do not control the watering work will also produce certain damage to the roots. Root is the nutrient absorption channel of all crops. If the root management is not in place, it will have a great impact on the growth and development of cucumber. Root aging is inevitable, but it can reduce root injuries.

4. Management

Cucumber is a perennial crop. In the later stage of growth, the yield of cucumber decreases obviously, and the fruit rate gradually decreases, so the vegetable farmers relax their management. The vines of the plant are not managed in time, resulting in excessive growth, which causes the lower leaves to be undernourished and begin to age, consuming a large amount of nutrients. In the later stage of cucumber growth, there is not enough nutrition for its growth, which is also one of the reasons for premature aging of cucumber.

5. Diseases

After cucumber grows to the later stage, its resistance ability is also weaker and weaker, and the bacteria and parasites in the vegetable garden will gradually increase. Without proper prevention, various diseases such as anthracnose and stem blight will occur in the middle and late stages. Disease will have a greater impact on the plant stems and leaves, affecting the photosynthesis of cucumber, leading to poor growth and development, resulting in premature aging.

The above is a brief introduction to the causes of premature aging of cucumbers. In fact, if improper medication is used in the management process, it will also cause certain premature aging phenomenon. Too much drug dosage and too short time interval make cucumber easy to produce phytotoxicity, reduce cucumber growth speed, aggravate cucumber premature aging or even premature aging.
