What is the reason why strawberries are not sweet?

Strawberry is a common delicious fruit, known as the "fruit queen", rich in nutritional value, sweet and delicious, often eat strawberries and promote digestion. So, what is the reason why strawberries are not sweet? Let's study together.

1. Small temperature difference between day and night

We all know that many fruits are sweeter when planted in an environment with a large temperature difference between day and night, because the temperature is higher during the day and lower at night, which is conducive to the accumulation of sugar in the fruit. If strawberries are not sweet, the temperature difference between day and night is very small. Like some areas with higher elevations, strawberries grown with large temperature differences between day and night are fragrant and sweet. When planting, the greenhouse is used to raise the temperature during the day and strengthen ventilation at night. Lower the temperature and artificially increase the temperature difference between day and night, so that the strawberries planted are absolutely sweet.

2. Lack of light

In the peak growing season and flowering and fruiting period of strawberries, there is a great demand for light, which requires 12-15 hours of light every day. Under the condition of sufficient light, strawberry plants grow vigorously, blossom and bear many fruits, and the fruit is sweet and large, and the yield is high. on the contrary, if the light is insufficient, strawberry plant growth is weak, leaves are dim, flowers are small and few, fruit coloring is poor, strawberries are not sweet and yield is low. So be sure to keep strawberries illuminated for a long time when planting.

3. Improper watering

Strawberry has a great demand for water in the growing period, but in the fruiting period, especially in the fruit expansion period, if it is watered too much, it will lead to excessive root water absorption, which is not only not conducive to the accumulation of sugar in the fruit, but also easy to cause root rot and death. The fruit tastes very sour, so we must pay attention to watering during the fruiting period, never watering too much, and watering according to the dry and wet soil. Do not water the soil until it is dry.

4. Poor fertilization

Strawberry growth needs sufficient nutrients, but the nutrients in the soil can not supply its growth, let alone blossom and bear fruit, so fertilization is also critical. Fertilization suggests the use of farm manure or organic fertilizer, less chemical fertilizer, generally 4000-5000kg per mu of farm manure, combined with some organic fertilizer or compound fertilizer.

5. Improper management

In order to consume too much nutrients in strawberry planting, it is necessary to prune strawberry stolons at different stages. Removing strawberry stolons at the right time can increase yield by about 50%, and excessive stems will consume a lot of nutrients. Therefore, when the stolon just grows, it should be removed immediately to ensure the large and sweet fruit, and it is also necessary to remove the flower buds in the bud stage, to sparse buds, to avoid excessive consumption of nutrients, and to promote fruit. In addition, strawberries grow new leaves all year, so timely removal of old or diseased leaves can reduce nutrient consumption and enhance permeability.

These are some of the reasons why the strawberries arranged by the editor are not sweet. I hope they can help the growers.
