Strawberries are cultivated in protected areas. In winter and spring, severe winds, heavy snow, heavy fog and other severe weather are often encountered. Although the frequency of these weathers is very low, once encountered, if the measures are not taken in time, strawberry production will suffer serious losses. The management experience in production is as follows: Windy day management In the greenhouse, if the strawberry is in the wind, the film will rise with the wind and fall down. If it is not managed in time, the film will be blown, causing the strawberry in the shed to suffer from freezing damage. Management measures: Block all the vents to prevent the wind from blowing into the shed to damage the strawberry plants and destroy the shed film. Pull the film line tightly and, if necessary, put a part of the grass to press the film. If there is a strong wind at night, it is necessary to press the grasshopper firmly. It is best to use a woven bag to hold a half bag of soil on a part of the grasshopper to prevent the wind from scraping off the grasshopper. Foggy day management In the spring, foggy weather often occurs. In this weather, the illumination of the greenhouse is less than 1/5 of the sunny day, the relative humidity of the air is above 95%, and the indoor temperature is below 15 °C. Such bad weather not only limits the photosynthesis of strawberry leaves, reduces photosynthetic products, and delays the maturity of strawberries. For example, in the cloudy days of strawberry flowering, it will greatly reduce the fruit setting rate of strawberries and produce deformed fruits, resulting in a decrease in yield. The quality is getting worse. Management measures: First, increase the artificial auxiliary lighting. Incandescent lamps can be used as a light source for heat treatment. Each 100-watt lamp is about 7.5 square meters. It is heated from 5 pm to 10 pm every day for 5 to 6 hours. The strawberry can increase yield by 30% to 50%, and the deformed fruit can be reduced by 50%. The second is reasonable temperature control. Temporary heating equipment is installed, heating is generally carried out at night, and short-term ventilation is carried out around noon. The daytime temperature in the control shed is around 20 °C, and the night temperature is above 10 °C. The third is assisted pollination. In the strawberry flowering period, the feeding of bees assisted pollination, and pollination by bees can increase the fruit setting rate by 50% to 70%, significantly increase the yield and quality of strawberries, and improve economic benefits.
