1. Temperature

Cucumber likes temperature. When the temperature exceeds the appropriate growth temperature, it will affect the growth of cucumber. The temperature suitable for cucumber growth is about 25 degrees. When the surrounding temperature increases continuously, especially in summer, the temperature increases to more than 35 degrees. Cucumber is prone to heat injury and sunburn, which reduces the photosynthesis of cucumber and cannot produce enough nutrients. Malnutrition leads to premature aging.

2. Fertilizer and water

Improper use of fertilizer and water during planting. Some vegetable farmers do not control the use of chemical fertilizer in the soil in order to control diseases and pests,mobile grow rack resulting in high soil concentration, affecting the growth and development of roots, and local necrosis in severe cases. The reduction of nutrient absorption capacity will do harm to the growth of plants. The application of fertilizer and water can not be reduced before seedling pulling, otherwise the lack of fertilizer and water will also ...
... lead to premature aging.

3. Root

The growth time of cucumber is gradually lengthened, and the aging speed of the root is also faster and faster. When the temperature is too high, the root will be damaged if the watering is not well controlled. The 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 unavoidable, but it can reduce root injury.

4. Manage

Cucumber is a perennial crop. At the later stage of growth, the yield of cucumber decreased significantly and the fruiting rate decreased gradually, so vegetable farmers relaxed management. The vine of the plant is not managed in time, resulting in overgrowth, which makes the lower leaves lack nutrition and begin to age, consuming a lot of nutrients. In the later stage of cucumber growth,strawberry stand frame there is not enough nutrition for its growth, which is also one of the reasons for the premature senescence of cucumber.

5. Disease

After the cucumber grows to the later stage, its resistance becomes weaker and weaker, and the bacteria and parasites in the vegetable garden will gradually increase. If prevention is not in place, various diseases will appear in the middle and later stage, such as anthrax, vine blight and so on. The disease will have a great impact on the stems and leaves of the plant, affect the photosynthesis of cucumber, lead to poor growth and development, and cause premature aging.
