Cucumber seedling management points

Water control: Roots and trees

Watering is not conducive to deep roots, easy to form a "top-heavy" phenomenon. In order to cultivate strong trees and lay a Foundation for later high-yield production, after the completion of the second water (warm seedling water), the water should be properly controlled, the soil should be dry, the soil should be removed, the amount of soil evaporation should be reduced, and the soil moisture should be ensured. This will promote the promotion of the root system. Tie to avoid prosperous growth. After the plant grows to 8 leaves, it is watered again.

Spraying medicine: promoting melon control

At present, most of the cucumbers planted are all females or strong females, which effectively avoids the problem of sitting in the quagmire. However, because the current season is even more cloudy, cucumbers are prone to "steamed heads," causing weak plants and yellowing of new leaves. phenomenon. First, we must pay attention to the temperature difference between day and night. Generally, the temperature difference between day and night is about 15C. Especially in continuous cloudy days, as long as it does not affect the normal temperature of the greenhouse, as far as possible to open the greenhouse, astigmatism can also effectively promote the photosynthesis of plants.

Top dressing: root resistance

In the case of severe changes in the sunny and sunny conditions, cucumbers often appear wilting. This is due to the poor development of the root system, the symptoms of leaf dehydration when the leaves turn cloudy after a cloudy day, and the plants with poor root development are particularly severe. Therefore, it is very important to raise roots at seedling stage.

Early root culture is particularly important. Generally, when the second water is poured, fertilizer containing amino acids and trace elements can be used to promote the development of the root system.

The use of cheap, hormone-containing fertilizers in the management of cucumber seedlings is not allowed, not only not rooting but also accelerating premature root failure and greatly reducing cucumber production.
