Strawberry smells delicious, tastes sour and sweet, has a refreshing fragrance, contains more nutrients, and is suitable for spring. It is called "the first fruit in spring" by many health experts.
Strawberries taste sweet when they are ripe. If it tastes sour, it may not be a naturally ripe strawberry. It is likely that fruit farmers used ripening agents to accelerate the ripening of strawberries in order to get them on the market in advance. Strawberry acid may also be a variety problem, because it contains a lot of fruit acid, so it tastes sour even when it is ripe.
Sour strawberries will be sweet.
1, put it for a while.
Generally, strawberries taste sour, indicating that the maturity is not enough. In this case, it is suggested that strawberries can be stored for a few days before eating, and the strawberries will gradually mature during the storage process, so that the sweetness of strawberries can also gradually increase.
Step 2 squeeze juice
If strawberries are sour when eaten directly, it is suggested that they can be juiced for drinking, and can be juiced with honey or other sweeter fruits, which can also improve the taste of strawberries.
Increase the sweetness of strawberries
1, lighting management
In order to improve the sweetness of strawberries, enough astigmatism can be provided. At noon on cloudy days, the straw curtain can be uncovered for strawberries planted in the greenhouse to receive light, and the film in the greenhouse can be kept clean, which can increase the light intensity, and the reflective film can be laid on the ground to increase the light among strawberry plants.
2. Water and fertilizer management
Water should be controlled during strawberry harvest to avoid excessive watering, organic fertilizer should be sufficient and trace elements should be supplemented. Potassium fertilizer can increase the sugar content of strawberry during fruit expansion, but nitrogen fertilizer should not be used too much.
3. Temperature difference management
The temperature of strawberry at night can be reduced properly during the fruit-bearing period, and the large temperature difference between day and night is beneficial to improve the sweetness of strawberry, which is kept at 5 ~ 8 degrees at night and at 18 ~ 25 degrees during the day to avoid excessive heat preservation in bad weather. The greater the temperature difference, the more dry matter accumulated and the sweeter the strawberry will be.
