Melon nursery shed multi-layer film covered with drawbacks

In recent years, in winter and spring, few cultivators for melon seedlings are usually built in winter, but most of them have simple nursery sheds in the melon shed. This kind of nursery shed has poor insulation effect, and the melon farmers often cover the multi-layer film to improve the insulation performance of the nursery shed. The number of film layers is often as many as five or six layers. In this way, although the insulation performance of the nursery shed has been enhanced, the light transmittance and the ventilation and dehumidification have been greatly reduced. Some melon farmers use the old film to cover the nursery shed to save money. The light transmittance in the shed is greatly reduced. The melon seedlings in the shed often grow poorly due to the low temperature, low light, and high humidity environment, and many diseases occur. How to solve these problems? The author suggests:

In order to ensure the insulation and light transmission effect of the nursery shed, the melon seedling shed in winter and spring should not be built in the arch shed. It should be built in the winter-warm greenhouse or specially constructed a small winter-warm nursery shed, so as to improve the heat preservation effect. The light transmittance can be increased due to the reduction of the number of thin film layers, and it is also not afraid that ventilation can be affected due to low temperature and ventilation.

When the nursery shed must be set in the arch shed due to the conditions, the following points must be made: The film covered by the nursery shed must use a new membrane. The number of layers covered by the nursery shed film should not exceed 3 layers. When the heat insulation effect is not reached, electric heaters, electric bulbs, warm water bags, etc. can be used to increase the temperature. If the temperature conditions permit, it is necessary to enhance ventilation and dehumidification so as to reduce the humidity in the booth. The film covering the nursery shed should be cleaned frequently to increase the light transmittance and improve the photosynthesis of the melon seedlings.
