How to do strawberry deformity
In the greenhouse, strawberries typically flower earlier than those in open fields, and during this early phase, there are fewer pollinators like bees. Therefore, it's recommended to introduce bees into the greenhouse once the first buds appear. Each standard greenhouse should have 2-3 bee hives placed evenly throughout the space to ensure a pollination rate of over 95%. Bees should be active between 8-9 AM and 3-4 PM for optimal pollination.
Temperature and humidity control is crucial after bud differentiation begins. Before insulation, daytime temperatures should be maintained between 20°C and 30°C, while nighttime temperatures should not drop below 10°C. During flowering and fruit set, it’s important to frequently ventilate the greenhouse to reduce humidity and maintain warmth. Daytime temperatures should stay between 20°C and 28°C, and nighttime temperatures should be above 5°C, with relative humidity kept at 50%-60%. Using anti-drip films can prevent water droplets from damaging the strawberry stigmas, and drip irrigation helps effectively lower air humidity.
Proper fruit thinning is essential to improve fruit quality. Removing secondary flowers, deformed fruits, and diseased or small fruits, along with regularly pruning old, yellow, or diseased leaves, reduces nutrient competition and improves air circulation and light exposure. This practice significantly lowers the occurrence of malformed fruits and helps concentrate nutrients, ensuring normal fruit development, increasing single fruit weight, and enhancing overall fruit quality.
When it comes to fertilization and disease management, it's best to use disease-free seedlings and mulching as preventive measures. Minimize or avoid pesticide use, especially during flowering. If severe diseases or pests occur, treat them before or after flowering, but never during bloom. In cold, rainy weather when humidity is high, move the beehives out of the greenhouse and apply fumigation agents. During the flower bud differentiation and development stage, applying nitrogen fertilizer or foliar sprays can support healthy flower development. Keep the soil consistently moist, especially during critical periods such as flower bud formation, flowering, and fruit expansion, by providing timely irrigation to meet the plants' needs.
