Analysis of the Latest Reasons Why Strawberries Grown Are Not Sweet

Strawberries are a common fruit for me, with a sweet and sour taste and rich nutrition. They are deeply loved by consumers and are grown in all regions of our country. Generally speaking, strawberries are sweet after ripening, but the strawberries grown by many growers are not sweet, which affects economic returns and causes great distress. So what are the reasons why strawberries are not sweet? Let's take a look with Qinnong Web.

1. Small day-night temperature difference

We all know that many fruits taste sweeter when grown in an environment with a large day-night temperature difference. This is because the daytime temperature is higher and the nighttime temperature is lower, which is conducive to the accumulation of sugars in the fruit. If strawberries are not sweet, this is largely the reason. When growing them, use a greenhouse to raise the daytime temperature, strengthen ventilation at night, lower the temperature, and artificially increase the day-night temperature difference. Strawberries grown this way will definitely be sweet.

2. Insufficient light

During the peak growth season and the flowering and fruiting period, strawberries have a relatively large demand for light, requiring 12-15 hours of light per day. When grown under sufficient light conditions, strawberry plants grow vigorously, have many flowers and fruits, and the fruits are sweet and large, with relatively high yield. Conversely, if light is insufficient, strawberry plants grow weakly, leaves are dull, flowers are small and few, fruit coloring is poor, the fruit is not sweet, and yield is low. Therefore, when growing strawberries, the light duration must be ensured.

3. Improper watering

Strawberries have a relatively large demand for water during the growth period, but during the fruiting period, especially during the fruit expansion period, if too much water is given, it will cause the root system to absorb too much water. This is not only unfavorable to the accumulation of sugars in the fruit, but also easily causes root rot and seedling death, and the resulting fruit tastes extremely sour. Therefore, during the strawberry fruiting period, be sure to pay attention to the amount of watering. Never water too much. Water according to the dry and wet condition of the soil, and water only after the soil looks dry.

4. Poor fertilization

Strawberry growth requires sufficient nutrients, but the nutrients in the soil cannot supply what it needs for growth, let alone flowering and fruiting. Therefore, fertilization is also very important when growing them. For fertilization, it is recommended to apply farmyard manure or organic fertilizer and use less chemical fertilizer. Generally, apply 4000-5000kg of farmyard manure per mu, combined with some organic fertilizer or compound fertilizer.

5. Improper management

When growing strawberries, in order to prevent them from excessively consuming nutrients, pruning should be carried out at different stages. Removing strawberry runners at the right time and in the right amount can increase yield by about 50%. Excessive runners will consume a large amount of nutrients, so when the runners have just grown, they should be removed immediately to ensure the fruit is large and sweet. In addition, during the bud stage, flower buds should also be removed in an appropriate amount to thin the buds, avoid excessive nutrient consumption, and promote fruiting. In addition, strawberries grow new leaves throughout the year, so removing old leaves or diseased branches and leaves at the right time can reduce nutrient consumption and also enhance air permeability.
