How to manage strawberries during the flowering period? A detailed explanation of the latest technical key points
Strawberry is a fruit that everyone is familiar with, and it has a very large planting area in our country. Strawberries have different growth stages, and as the strawberry growth stage changes, its management methods will also change to some extent. During the strawberry flowering period, the amount of flowering directly affects the strawberry yield, so management during the flowering period is very important. Then the editor has brought you the key management technical points for the strawberry flowering period. Let's take a look!
1. Water and fertilizer management
Half a month before the strawberries bloom, an appropriate amount of phosphorus should be supplemented for the strawberries. Then spray the flower buds with agents such as Huaduole to promote the absorption of trace elements by the strawberries and improve the flowering and fruiting rate of the strawberries. During the strawberry flowering period, the nutritional demand is relatively large, but when fertilizing, attention should be paid to fertilizer selection and dosage. It must not be excessive, to prevent fertilizer damage to the strawberries. During the flowering period, keep the soil moist and water regularly. The amount of water should not be excessive, to prevent root rot from waterlogging. Therefore, when there is too much water or water accumulation in the field, drain it in time. Ensure normal flowering and fruiting of the strawberries.
2. Control light
The strawberry flowering period has a very large demand for light. If there is insufficient light during the flowering period, the pollination and fertilization rate of the strawberries will be seriously reduced. However, direct sunlight is also not suitable, so during the flowering period it is best to cover the greenhouse with a film with strong light transmission. Then clean the film regularly to ensure light transmission. During the flowering period, ensure 13-14 hours of light per day. When natural light is insufficient, artificial supplemental lighting should be carried out. Set up light bulbs in the greenhouse, evenly distributed, for artificial supplemental lighting. In an environment with sufficient light, strawberries grow quickly and can mature 2-3 weeks earlier.

The quality of natural pollination of strawberries is relatively poor, and the fruits produced are of poor quality, with many small fruits and deformed fruits. Therefore, during the flowering period, artificial pollination should be carried out appropriately, using a brush, cotton swab, etc. to gently brush the stamens of male flowers, and then brush them onto the female flowers. However, the main method is still to place bees in the strawberry field and use bees for pollination. Also, because the artificial pollination method is time-consuming and labor-intensive, it not only increases labor costs, but the pollination rate cannot be greatly increased. When there are no bees, an appropriate spray of Huaduole can be used to improve the fruit-setting rate of strawberries.
4. Temperature and humidity management
During the strawberry flowering period, control soil moisture at about 45%, ensuring the soil is moist but not waterlogged. When there is too much water, appropriately reduce humidity. When the water content is insufficient, water in time. When watering, pay attention to the weather. Do not do it under high-temperature exposure such as at noon, to prevent water from evaporating too quickly. Focus on small-drop drip irrigation and watering more with less each time, to prevent waterlogging damage to the strawberries. Finally, during the flowering period, control the temperature well. The daytime temperature should be maintained at about 22 degrees, and the nighttime temperature should not be lower than 8 degrees. If the temperature is too high or too low, it will affect the pollination of strawberries and reduce the fruit-setting rate.
The above is a brief introduction to the key management technical points for the strawberry flowering period. Of course, the most important thing is still to do a good job in the prevention and control of pests and diseases. Common pests and diseases during the strawberry flowering period include powdery mildew, aphids, etc. Pests and diseases will seriously harm the growth of strawberries. Management must be strengthened to reduce the incidence of pests and diseases. That is all for today's introduction. This article is for reference only. Thank you everyone for reading and supporting.
