How to manage strawberries during the flowering period? All the key technical points are here
Strawberry is a fruit everyone is familiar with, and it has a very large planting area in China. 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 number of flowers directly affects strawberry yield, so management during the flowering period is very important. So today I bring you the key technical points for strawberry flowering period management. Let's take a look!
1. Water and fertilizer management
Half a month before strawberries bloom, supplement them with an appropriate amount of phosphorus. Then spray the flower buds with agents such as Huaduole to promote the absorption of trace elements by strawberries and improve the flowering and fruiting rate. During the strawberry flowering period, nutritional demand is relatively high, but when fertilizing, attention must be paid to fertilizer selection and dosage. Do not overdo it, to prevent fertilizer damage to strawberries. During the flowering period, keep the soil moist and water regularly, but the amount of water should not be excessive, to prevent root rot from waterlogging. Therefore, when there is too much water or standing water in the field, drain it promptly. Ensure normal flowering and fruiting of strawberries.
2. Control light
Strawberries have a very high demand for light during the flowering period. If there is insufficient light during the flowering period, the pollination and fertilization rate of strawberries will be seriously reduced. However, direct sunlight is also unsuitable, so during the flowering period it is best to cover the greenhouse with a film with strong light transmittance. Then clean the film regularly to ensure light transmission. During the flowering period, ensure 13-14 hours of light each day. When natural light is insufficient, carry out artificial supplemental lighting. 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.
3. Artificial pollination
The quality of natural pollination in strawberries is relatively poor, and the fruit produced is 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. 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, you can appropriately spray Huaduole to increase the fruit-setting rate of strawberries.
4. Temperature and humidity management
During the strawberry flowering period, keep soil moisture at about 45%, ensuring the soil is moist but not waterlogged. When there is too much water, reduce humidity appropriately; when the water content is insufficient, water promptly. When watering, pay attention to the weather. Do not do it at noon or under high-temperature exposure, to prevent water from evaporating too quickly. Mainly use small-drop drip irrigation and water more times with a smaller amount, to prevent waterlogging damage to strawberries. Finally, during the flowering period, control the temperature well. The daytime temperature should remain 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 strawberry pollination and reduce the fruit-setting rate.
The above is a brief introduction to the key technical points for strawberry flowering period management. Of course, the most important thing is still to do a good job in pest and disease prevention and control. Common pests and diseases during the strawberry flowering period include powdery mildew, aphids, etc. Pests and diseases will seriously harm strawberry growth, so 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 all for reading and supporting.
