In the event of snowfall, grasshoppers will become wet, which not only affects the heat preservation, but also makes it difficult to roll the grass, and it is easy to be crushed. The snow on the grasshoppers must be removed in time, and the snow beside the shed wall must be removed to prevent the snow from melting. The soil seeps into the shed, not only taking away the heat, but also damaging the shed wall. Clearing the snow on the shed film during the day enhances the light transmission of the shed. In order to increase the temperature and prevent frost, a small arch shed can be buckled in the shed. The grasshopper cannot be exposed all at once to prevent the strawberry from becoming too sunny after the snow and the light is too strong, resulting in severe dehydration and permanent wilting of strawberries.

In case of cloudy weather, pay attention to increase artificial auxiliary lighting. Incandescent lamps can be used as the light source for heating treatment. Each 100-watt lamp is about 7.5 square meters, and it is heated for 5-6 hours every day from 5 pm to 10 pm. Heating is generally performed at night, and short-time ventilation is performed around noon to control the temperature in the shed during the day at about 20 ° C and the night temperature above 10 ° C. During strawberry flowering period, pay attention to release bees for auxiliary pollination to improve fruit setting rate and strawberry yield and quality.
In winter, the greenhouse strawberry strawberry tube
In case of strong wind, the shed film will swell with the wind and beat up and down. If it is not managed in time, the shed film will be blown and the strawberries in the shed will be damaged by freezing. All ventilation openings should be blocked tightly, and the film line should be tightly tightened. If necessary, a part of the grasshopper should be put down to compress the shed film firmly. If there is a strong wind at night, it is best to use a woven bag with half a bag of soil to press on some of the grasshoppers to prevent the windmill from blowing them off.
