Greenhouse management in winter

Is the thermal insulation of the greenhouse good? How does the greenhouse keep warm?

1. How to reduce minor freezing damage?

Vegetable management in the pre-snow protection area. When it is cloudy, the grass curtain should be exposed normally. For the precious astigmatism, the time should be controlled on a sunny day and 1 hour after the opening of the grass curtain. The application of organic fertilizer can strengthen the soil. The heat capacity can buffer the temperature drop caused by heat loss in cloudy days, and promote the root system to improve cold resistance. Appropriate moisture control is very important for reducing the relative humidity of indoor air, and at the same time can create an environment with moist soil and dry top soil. It is recommended to use two-color plastic film to cover (silvered below black) to increase temperature, humidity and weeding.

2. Is the thermal insulation performance of the greenhouse good?

How does the greenhouse keep warm?

How to reduce the slight frost damage?

Take timely disaster prevention and prevention measures. After the cold wave cooling and snow disaster warning is issued, disaster prevention measures should be taken in time, and the areas where snow disasters may occur Take precautionary measures: dredging ditches and digging drainage ditches on both sides of the greenhouse to ensure drainage after snow and prevent stains; prepare agricultural materials for disaster prevention and relief, such as drainage machinery and equipment, pesticides, fertilizers, agricultural films, greenhouse supporting materials, and thermal insulation materials. Strengthen the greenhouse in advance. Along the longitudinal axis of the large (middle) canopy and scaffolding, every 2-3 meters, use bamboo and other supports to support and strengthen the canopy to improve the compression resistance of the canopy and prevent the snow from crushing the canopy. After the snow disaster and cold wave warning is issued, day and night inspections should be carried out in time to clear the snow on the roof.

Snow should be placed on straw curtains or insulation bedding in time. The straw curtains or insulation coatings are covered with a cold-proof film. Close the greenhouse door and close the air inlet with a film to prevent cold wind from entering. When encountering a sudden blizzard, when the snow cannot be removed from the roof (especially the connected greenhouse), special emergency measures should be taken to break the membrane to protect the scaffold. The crops in the shed should be discarded to fully protect the shelves and reduce losses. If there are external shading equipment on the scaffold, the shading net on the external shading should be closed and tightened to prevent snow damage. The photosynthesis of vegetable crops, snow is very weak, there are few synthetic photosynthetic products, which reduces the waste of tongue. The canopy temperature at night should be controlled 2℃-3℃ lower than that on clear days and nights.

In the case of snow on a cloudy day, the respiratory consumption of vegetables is greater than that of photosynthesis, and the greenhouse will accumulate a large amount of harmful gases such as carbon dioxide. Therefore, when the snow stops releasing wind, harmful gases will be emitted in time. Emergency heating measures. If you encounter a sudden snowfall to cool down, and you have no preparations, please put your home heaters and heaters in the shed, not to mention that there are no wires and plug rows. This is a daily necessities in the shed. In 2015, an agricultural base in Shanghai also experienced the biggest cooling in 30 years, with the temperature dropping to minus 12.5 degrees. The greenhouse does not have straw curtains and no thermal insulation cover. It is just a multi-layer cover before cooling. There are three layers of film (not including two-color plastic film). There is no problem for long wintering on weekdays, but it is not good for the low temperature of minus 10 degrees. Temporary heaters, heaters, and half acre sheds are placed two and one head, and the temperature in the shed reaches about 4 degrees.
