Latest Management Model for Cucumbers During Continuous Cloudy Days
The planting area of cucumbers in our country is very large. When growing cucumbers, we need to carry out management work according to changes in the weather. Cucumbers have a relatively large demand for temperature and light, so when encountering continuous cloudy days, it is very unfavorable to their growth. Therefore, when encountering continuous cloudy days, we must pay attention to strengthening management. So how should cucumbers be managed during continuous cloudy days? Below, the editor brings you the management model for cucumbers during continuous cloudy days. Let's take a look!
1. Increase light
Under continuous cloudy days, the natural light duration will decrease significantly. The light inside the greenhouse is seriously insufficient, causing the content of photosynthetic substances in cucumber plants to decrease and excessive nutrient consumption, thereby causing premature aging of cucumbers. So on rainy days, if the light inside the greenhouse is too weak, then the greenhouse film should be wiped in time to improve the light duration and intensity inside the greenhouse. Enhance leaf photosynthesis, increase the accumulation of photosynthetic substances, and reduce leaf premature aging. Then also pay attention to controlling the temperature well. Under continuous cloudy days, the daytime temperature inside the greenhouse should be maintained at about 25 degrees, and at night it should be maintained at about 15 degrees.
2. Protect the root system
The root system of cucumber plants is distributed relatively shallowly, generally concentrated in the topsoil about 20 cm deep. Therefore, it is very sensitive to changes in ground temperature, water and fertilizer. So during continuous cloudy weather, we should pay attention to protecting the root system well. During continuous cloudy days, the transpiration of cucumber leaves is relatively small. Therefore, except when the soil is very dry, watering is generally not suitable. Avoid excessive humidity, which can cause root rot. After continuous cloudy days, it is also not suitable to water immediately, because at this time the plants are in a recovery period and root vitality is relatively poor. If watering is too early, then the roots will be seriously damaged and the plants will wilt.
3. Supplement nutrition
During continuous cloudy days, the nutrients produced by the plants themselves are very few. If cucumber plants lack nutrients, then their growth is very unfavorable. So we should also pay attention to supplementing nutrition well. Mainly use foliar fertilizer to supplement nutrients to the leaves, which can effectively enhance the stress resistance of the plants. Foliar fertilizer can use full-nutrient foliar fertilizer, chitin, and brassinolide, etc. It can effectively promote the synthesis of chlorophyll in cucumber leaves and enhance the photosynthetic efficiency of cucumbers.
4. Management after continuous cloudy days
Management work after continuous cloudy days turn clear is also very important. Because the leaf area of cucumbers is relatively large, their transpiration coefficient is also very high. But because the root system is not well developed, it is prone to damage. So after the weather suddenly turns clear, the sharp changes in light and temperature will cause great harm to cucumber plants. Therefore, after it turns clear, we should pay attention to shading work, adjust light and temperature well, and let cucumbers gradually adapt to environmental changes. At the same time, apply an appropriate amount of root-nourishing and root-promoting fertilizer, combined with fully water-soluble fertilizer, to prompt cucumber plants to recover their growth as soon as possible.
The above is a brief introduction to the management model for cucumbers during continuous cloudy days. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
