How to manage strawberries during the fruit-swelling stage? Latest technical method tutorial

Strawberries are distributed all over our country and are a fruit loved by many people. Although strawberries are expensive, their market demand is very large because they are sweet and delicious and rich in nutrients. And when growing strawberries, we need to do a good job of management. This is especially true during the fruit-swelling stage, so how should strawberries be managed during the fruit-swelling stage? Now let's take a look together with the editor at the management techniques for strawberries during the fruit-swelling stage!

1. Temperature management

After strawberries enter the fruit-swelling stage, we must control the temperature well. At this time, the temperature must not only pay attention to the fruit swelling of strawberries, but also meet the needs of flower bud differentiation. If the daytime temperature is appropriately higher, it is very favorable for strawberry fruit swelling. But it will affect flower bud differentiation, thereby affecting the yield in the middle and late stages. But if the temperature is too low, the opposite phenomenon will appear: strawberry fruits will be on the small side, and their commercial value will be affected as a result, thereby reducing planting benefits. Therefore, in order to ensure the quality of strawberries, during the fruit-swelling stage we should appropriately lower the night temperature, keeping the daytime temperature at around 22 degrees and the nighttime temperature at around 7 degrees, maintaining a relatively large day-night temperature difference.

2. Humidity management

During the strawberry fruit-swelling stage, humidity management is also very important. The humidity in the orchard must not be higher than 80%. Although during the fruit-swelling stage, higher humidity can promote fruit expansion and improve strawberry quality. But it must not be too high either. If it exceeds 80%, gray mold is very likely to occur. Therefore, humidity should be controlled at around 70%. When it is too high, watering should be stopped and humidity should be drained in time. Likewise, when humidity is too low, watering should be done in time to increase humidity. Carry out ventilation and dehumidification work properly according to the actual situation to ensure normal growth and fruit swelling of strawberries.

3. Plant management

First, we should remove the old leaves and diseased leaves from the strawberry plants to improve the plant's air permeability, promote fruit expansion, and avoid the threat of disease. Then, according to the plant's growth vigor, we should do a good job of flower thinning and fruit thinning, keeping about six fruits per plant, and removing excess fruits to avoid competing with each other for nutrients and affecting fruit swelling. In addition, during the strawberry fruit-swelling stage, new runners will still grow, so we should also remove excess runners in time and then disinfect appropriately. Finally, we should also remove the side buds on both sides of the plant to prevent the buds from competing for the nutrients needed for fruit expansion, ensuring normal expansion of strawberry fruits.

4. Water and fertilizer management

The expansion of strawberry fruits has a very great relationship with water. Therefore, we should also pay attention to doing a good job of watering, and pay attention to controlling the amount of watering, mainly using small-drop drip irrigation. If watering on sunny days, close the greenhouse after each watering, and ventilate again after the temperature rises. In the late fruit-swelling stage, control the amount of water well to avoid excessive water reducing strawberry quality. Because when strawberry fruits expand, the growth rate is very fast, so fertilizer should be applied about once every half month, mainly with high nitrogen and potassium and low phosphorus. At the same time, we should also pay attention to appropriately spraying foliar fertilizer to supplement trace elements such as boron and magnesium.

The above is a brief introduction to the management techniques for strawberries during the fruit-swelling stage. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
