Strawberry management in windy days. In winter, if the strawberry in the greenhouse encounters strong winds, the film will swell with the wind and beat up and down. If it is not managed in time, the film will be blown and the strawberries in the greenhouse will suffer freezing damage. On a windy day, all vents should be blocked tightly to prevent strong wind from blowing into the shed; tighten the film line, and if necessary, put down a part of the grass thatch to press the shed film firmly. If there is a strong wind at night, use braiding. The half-bag of soil is pressed on part of the grass thatch to prevent the grass thatch from being blown off by the strong wind.
Strawberry management in snowy days. Snowfall in winter, the outside temperature is not very low, it may melt while snowfall, soaking grass thatch, which affects heat preservation and easily crushes the scaffold. Therefore, strawberry management should uncover the grass thatch before snowfall, clear the snow after the snow stops, and then put down the grass thatch. There is a blizzard in the middle of winter, and the outside temperature is too low to open the grass thatch, otherwise the strawberries in the shed will be frozen. In addition, the heavy snow on the grass thatch can easily crush the scaffold. The snow on the grass thatch must be cleared in time, and the snow on the shed wall must be cleared to prevent the snow from melting into the shed through the soil. Not only take away heat, but also damage the shed wall. Cleaning the snow on the shed film during the day can enhance the light transmittance of the shed; increase the shed temperature, take temporary measures to reasonably regulate the shed temperature, and pay attention to prevent air damage; in order to increase the temperature and prevent freezing, small arch sheds can be buckled in the shed; improve the light, It is necessary to uncover the grass and thatch early during the day, but be careful not to uncover it all at once, in case it turns clear after snow and the sun is too strong, which may cause serious dehydration of strawberries and permanent wilting.
Strawberry management on cloudy and foggy days. One is artificial auxiliary lighting. The incandescent lamp can be used as the light source for heating treatment. Each lamp of 100 watts illuminates about 7.5 square meters, and it is heated from 5 pm to 10 pm every day for 5-6 hours; the second is reasonable temperature control. Install temporary heating equipment. The heating is usually carried out at night and short-time ventilation is carried out around noon. The temperature in the shed is controlled to be around 20°C during the day and 10°C at night; the third is auxiliary pollination. In the flowering period of strawberry, pollination by bees can increase the fruit setting rate by 50% to 70%, which can maximize the yield and quality of strawberries and enhance economic benefits.
