Strawberries: Insulation of the buckle shed to cope with the drop

The optimum temperature for strawberry flowering is 23-28°C. When the temperature drops, timely insulation of the shed is the key to the cultivation of strawberries in the greenhouse. If the shed is too early, it will affect the differentiation of the flower buds of strawberry, which will lead to a reduction in yield. If the shed is too late and the temperature is below 5°C at night, it will cause the dormancy of the strawberry and the dwarfing and stunting of the plants. 6-7 °C at night is the critical temperature during the incubation period.

Affected by the strong cold air, from the night of October 24 to the 26th, a northeastern gale of over 7 magnitude occurred in the province. The minimum temperature drop in 48 hours was 3.2-10.3°C, and the minimum temperature in 26 days was 5-8°C in the Huaibei region. The Huaihe River 9-13°C to the south. It is expected that there will be a cold air southward on November 2 and the temperature will drop again. Strawberries need to be insulated by sheds to promote normal growth. According to the survey, some farmers in Yishui County have begun to buckle and cover the membranes, but most have not yet begun.

At the moment, it is necessary to seize the suitable weather shed cover film to ensure that the strawberries are not affected by low temperatures. Recently, strawberries have successively inhaled the inflorescences. If they have not yet covered the black mulch, they must pay close attention to the time. Otherwise, the inflorescences will be broken during the operation of the mulching film and affect the yield. Strengthen the greenhouse temperature and humidity management; a small amount of repeated fertilization. Before flowering, flower buds should be properly sparse; buds and insects should be removed in time. In the early stages of blooming flowers, bees were placed at a proper time to increase the fruit setting rate.
