Winter insulation is the key to the management of solar greenhouses, especially in the deep winter season. The outside temperature has dropped to minus zero. Once the cold wind enters the greenhouse, it will cause great harm to the crops. How can we prevent the crops from being chilled? Windshield at the entrance From the buffer room to the greenhouse, it is necessary to open and close the door so that the vegetables are vulnerable to weak growth, low yield, and prone to frost damage. If a piece of membrane with a length twice that of the door and a width of 1.5-2 meters is hung in the south side of the walkway inwards and the lower side is tight, the opening and closing doors will not be so cool and the damage to the crop will be reduced. For thick soil wall greenhouses, membranes can be placed on the indoor side, and thick curtains are recommended, which can effectively alleviate the cold air blowing at the entrance. Uptake outlet windshield In winter greenhouses, ventilation still takes place. When the upper air inlet is opened, the cold air directly enters the greenhouse. The temperature in the area directly under the air outlet changes greatly. The crop often encounters a cold wind. It is necessary to install a windshield below the air inlet. The method is: Set a piece of film with a length of 1.5 meters and a greenhouse equal to 1 meter below the upwind outlet. Tighten and flatten it with a steel wire so that it is in a state of high in the south and low in the north. Hanging on the steel pipe in the south and fixing it on the column in the north. The film winter can be wind and summer can be rain, at the same time, the drip on the membrane can flow directly to the walkway, not only preventing cold damage, but also avoiding the water droplets falling on the plants, resulting in the occurrence of disease, killing more. Forefront of anti-cold film In winter, the crops at the front of the greenhouse are generally growing poorly and are prone to disease. The main reason is that the temperature at the front edge changes greatly and the humidity is high, especially at night. If a piece of mulch (new) is set on the front edge, the upper side is fixed on the steel wire and the lower side is draped to the ground, which can prevent the crop from causing low temperature damage from the shed film, and can block the cold fog in the front. The effect is obvious. Disclaimer: Some articles in this website have been transferred from the Internet.
