How to solve dripping water in vegetable greenhouse in winter

Crops cultivated in winter often choose greenhouse cultivation, but because of the large temperature difference between inside and outside the greenhouse, the humidity in the greenhouse is high, and water droplets will inevitably be produced on the inside of the greenhouse film. And the harm of greenhouse film dripping is also great, let's take a look at the harm and solutions of dripping water in greenhouse in winter.

Harm of dripping water in greenhouse

1. The light transmittance decreases.

Dripping water from the greenhouse film will reduce the light transmittance by at least 20% Murray 30%, and will also absorb a large amount of heat in the greenhouse, affecting the increase of the greenhouse temperature. In the deep winter, the light and temperature are already low, the water dripping of the greenhouse film will reduce the light transmittance of the greenhouse film, which will make the light in the greenhouse weaker, the photosynthesis of crops will be seriously affected, and the temperature will also be affected, causing great harm.

2. Cause chilling injury

When the water droplets on the greenhouse film splash on the plants, it will often cause chilling injury because the temperature of the water droplets is too low, which will affect the normal growth of vegetables.

3. Induced diseases

The long-term existence of dew can induce a variety of diseases, especially the outbreak of bacterial and egg diseases, which requires liquid water and wounds. Dripping just creates these two conditions. Dripping water in the shed or increasing the humidity in the shed is conducive to the occurrence of most fungi. Especially in cloudy and rainy days, the temperature in the shed is low, the humidity is high, and the disease occurs seriously.

II. Solutions

In order to solve the problem of water dripping of greenhouse film, it is necessary to consider many aspects, such as shed structure, film quality and so on. when building a new shed, we should pay attention to improve the shed structure and increase the surface intersection of the shed. Select high-quality non-dripping film, in the new greenhouse film, pull the greenhouse film tight, so that the greenhouse film flat, can also reduce greenhouse film dripping. It can also be sprayed on the inside of the film, such as silicone auxiliaries, to improve the surface ductility of the greenhouse film and avoid the formation of water droplets.

The above is the introduction of how to solve the problem of dripping in the vegetable greenhouse in winter. I hope it can help you. If you want to know more about it, please follow us.
