In case of snowfall, the grass thatch will get soaked, which will affect the heat preservation, it will be difficult to roll the grass thatch, and it is easy to crush the greenhouse. The snow on the grass thatch must be removed in time, and the snow beside the shed wall must be cleared to prevent the snow from melting. The soil penetrates into the shed, which not only takes away heat, but also damages the shed wall. Sweep the snow on the shed film during the day to enhance the light transmittance of the shed. In order to increase the temperature and prevent freezing, a small arch shed can also be buckled in the shed. The grass thatch can't be fully exposed at one time, in case it turns clear after snow, and the sun is too strong, which will cause serious dehydration and permanent wilting of strawberries.
In strong winds, 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 suffer freezing damage. All vents should be blocked tightly, the film line should be tightened, and a part of the grass thatch should be put down if necessary to secure the film. If there is a strong wind at night, it is necessary to use a woven bag with half a bag of soil to press part of the grass thatch to prevent the grass thatch from being blown off by the wind.
In case of cloudy and foggy weather, pay attention to increasing artificial auxiliary lighting. The incandescent lamp can be used as the light source for heating treatment. Each 100 watt lamp illuminates about 7.5 square meters, and it is heated for 5-6 hours from 5 pm to 10 pm every day. Heating is generally carried out at night, and ventilation is carried out for a short time around noon. The temperature in the shed is controlled to be around 20°C during the day and 10°C at night. During the strawberry flowering period, pay attention to stocking bees for auxiliary pollination to increase the fruit setting rate and the yield and quality of strawberries.
