Key technical points of strawberry flowering management

Strawberry is a kind of fruit that everyone is familiar with, and it has a very large planting area in our country. Strawberries have different growth stages, and their management methods will change with the change of strawberry growth stages. During the flowering period of strawberries, the amount of flowering directly affects the yield of strawberries, so the management of the flowering period is very important. Then the editor brings you the key points of strawberry flowering management technology, let's have a look!

1. Water and fertilizer management

Add the right amount of phosphorus to strawberries half a month before flowering. Then spray Huaduole on the buds to promote the absorption of trace elements in strawberries and improve the flowering and fruiting rate of strawberries. During the flowering period of strawberries, the nutritional demand is relatively large, but when fertilizing, we should pay attention to the selection and amount of fertilizer, not excessive, to prevent strawberry fertilizer damage. Keep the soil moist during flowering, watering regularly, water should not be excessive to prevent root rot, so when there is too much water or stagnant water in the field, it should be drained in time. Ensure that strawberries blossom and bear fruit normally.

2. Control lighting

The demand for light during the flowering period of strawberries is very large, and the lack of light during flowering will seriously reduce the pollination and fertilization rate of strawberries. However, it is not suitable for direct sunlight, so it is best to cover the greenhouse with a highly transparent film during the flowering period. Then regularly clean the film to ensure light transmission, in the flowering period to ensure that there are 13-14 hours of light every day. When the natural light is insufficient, the artificial light filling work should be carried out. Set up light bulbs in the greenhouse, distribute them evenly, and replenish the light artificially. In the environment with sufficient light, strawberries grow fast and mature 2-3 weeks earlier.

3. Artificial pollination

The natural pollination quality of strawberry is relatively poor, the fruit quality is poor, and there are many small fruits and abnormal fruits. Therefore, artificial pollination should be carried out properly during the flowering period, using brushes and cotton swabs to gently brush the stamens of male flowers, and then brush them on the female flowers. However, bees are mainly put into strawberry fields and pollinated by bees. Because the method of artificial pollination is time-consuming and laborious, not only the labor cost is increased, but also the pollination rate can not be greatly increased. In the absence of bees, appropriate spraying of Flower Dole can improve the fruit setting rate of strawberries.

4. Temperature and humidity management

Keep the soil moist at about 45% during the strawberry flowering period to ensure that the soil is moist without stagnant water. When there is too much moisture, it should be properly drained, and the water content should be watered in time. Pay attention to the weather when watering, not in the high-temperature exposure environment such as noon, to prevent the water from evaporating too quickly. Drip irrigation with small water and a small amount of water should be used to prevent strawberries from waterlogging. Finally, the temperature should be controlled during the flowering period. The temperature should be kept at about 22 degrees during the day and no less than 8 degrees at night. Too high or low temperature will affect the pollination of strawberries and reduce the fruit setting rate.

The above is a brief introduction to the technical points of strawberry flowering management, of course, the most important thing is to do a good job in the prevention and control of diseases and insect pests. Common diseases and insect pests in strawberry flowering period are powdery mildew, aphids, etc., diseases and insect pests will seriously harm the growth of strawberries, it is necessary to strengthen management and reduce the incidence of diseases and insect pests.
