The flower organs of temperature strawberries are sensitive to low temperature. For example, the pistil color will turn black when it encounters a low temperature of -2°C during the flowering period for 1 hour. Therefore, the thermal insulation performance of greenhouse facilities should be improved. The temperature of the greenhouse should be kept at 20℃～25℃ during the day, 8℃～18℃ at night, and the ground temperature should be kept at 18℃～22℃. If the temperature is low during this period, the anthers cannot be scattered, which will increase the proportion of deformed fruits.
Humidity The optimum humidity for strawberry anther cracking is 30%-50%, and the optimum humidity for stigma fertilization and pollen germination is 50%-60%. Too low or too high humidity is not conducive to normal pollination and fertilization. Due to the closed environment in the strawberry greenhouse, if it is not ventilated in time, the humidity will often be too high. In the production, we can use drip-free greenhouse film, high-ridge mulching film to reduce soil moisture evaporation, and short-time ventilation at noon to reduce the air humidity in the greenhouse. .
Although the flower of the bee strawberry is a bisexual flower, the flowering period of strawberry cultivated in the greenhouse is in the severe winter and cold season. The low temperature, high humidity, few insects and the pollen can not fly easily in the greenhouse, leading to poor pollination and producing deformed fruits. The beehives can be placed in the greenhouse during the flowering period, and bees can be used to assist in pollination to reduce malformed fruits.
