Management techniques of Strawberry Fruit expansion period

Strawberry is distributed all over our country, and it is a kind of fruit loved by many people. Although the price of strawberries is high, but because strawberries are sweet, delicious and nutritious, the market demand for strawberries is also very large. When growing strawberries, we need to do a good job of management. Especially in the fruit expansion period, so how to manage the strawberry fruit expansion period? Let's take a look at the management technology of strawberry fruit expansion period with the editor.

1. Temperature management

After strawberries enter the fruit expansion period, we should control the temperature. At this time, we should not only pay attention to strawberry fruit expansion, but also pay attention to meet the needs of flower bud differentiation. If the temperature is a little higher during the day, it is very beneficial for strawberries to expand the fruit. However, it will affect the flower bud differentiation, thus affecting the yield in the middle and later stage. However, if the temperature is too low, there will be the opposite phenomenon, strawberry fruit is too small, the commodity value will be affected, thus reducing the planting efficiency. Therefore, in order to ensure the quality of strawberries, we should appropriately reduce the night temperature during the fruit expansion period, keep the temperature at about 22 degrees during the day and 7 degrees at night, and maintain a large temperature difference between day and night.

2. Humidity management

In the strawberry fruit expansion period, humidity management is also very important. The highest humidity in the orchard should not be higher than 80%, although during the fruit expansion period, higher humidity can promote fruit expansion and improve the quality of strawberries. But it should not be too high, if it exceeds 80%, it is extremely prone to gray mold. Therefore, the humidity should be controlled at about 70%. If the application is too large, stop watering and drain the moisture in time, and if the humidity is too low, it should be watered and wet in time. Do a good job of ventilation and humidity reduction according to the actual situation to ensure the normal growth and expansion of strawberries.

3. Plant management

First of all, we should remove the old leaf disease leaves from the strawberry plant to improve the plant permeability, promote fruit expansion and avoid the threat of disease. Then according to the growth of the plant to do a good job of flower and fruit thinning, each plant to retain about six fruits, remove excess fruit, avoid competing with each other for nutrients and affect fruit expansion. In addition, in the strawberry fruit expansion period, there will still be new stolons growing, so we should also remove the excess stolons in time, and then disinfect them properly. Finally, we have to break off the lateral buds on both sides of the plant to prevent the buds from grabbing the nutrients needed for fruit expansion and to ensure the normal expansion of strawberry fruit.

4. Water and fertilizer management

The relationship between strawberry fruit expansion and water content is very great. Therefore, we should also pay attention to do a good job of watering, we should pay attention to control the amount of water, mainly small water drip irrigation. If watering on a sunny day, the greenhouse should be closed after each watering, and ventilation should be carried out when the temperature rises. In the later stage of fruit expansion, it is necessary to control the amount of water to avoid excessive moisture and reduce the quality of strawberries. Because strawberry fruit expands, the growth rate is very fast, so it is necessary to topdressing once in half a month, mainly with high nitrogen, potassium and low phosphorus. At the same time, we should also pay attention to properly spraying foliar fertilizer to supplement boron, magnesium and other trace elements.

The above just-in-time strawberry fruit expansion management technology is briefly introduced. That's all for today's introduction. This article is for reference only. I hope it can help you all.
