What causes hollow strawberries?
Strawberries are planted on a fairly large area in our country and are loved by many people, so their market demand is also very large. However, although many people grow strawberries, many problems often arise when growing them, and hollow fruit is one of them. When strawberries are hollow, the yield is greatly affected. So what causes hollow strawberries? Below, the editor will give you a brief introduction. Let's take a look!
1. Improper temperature
During the fruit-setting stage, strawberries have very high temperature requirements. If the temperature is too low during the fruit-setting stage, the impact on strawberry growth is very great, causing the development rate to be extremely slow. And if the temperature gradually rises later, it will cause strawberries to grow faster. This results in uneven growth before and after, leading to the phenomenon of splitting and cavities. However, the temperature must not be too high either, especially during the flowering stage. If the temperature exceeds 35°C and lasts for a long time, it is very unfavorable for strawberry flowering, affecting pollination and fertilization of the flowers, and causing obstruction of fruit growth and development.
2. Light reasons
Light is also very important for the growth of strawberry fruit. During the flowering and fruiting stage, strawberries need an environment with strong light. If light is insufficient, it is very unfavorable for fruit development. Especially in seasons with insufficient natural light, such as autumn and winter and early spring, the photosynthetic capacity of strawberries declines, resulting in insufficient photosynthetic products. This reduces the nutrient accumulation of strawberries, causing insufficient nutrient supply, which leads to undesirable phenomena such as hollow strawberries. Therefore, everyone must pay attention to controlling light well. When natural light is insufficient, artificial supplemental lighting should be done well.
3. Boron deficiency
The element boron is an indispensable nutrient element in strawberry growth. Boron plays a key role in nutrient transport within strawberries. If boron is deficient, strawberry fruit will form hollow fruit due to insufficient nutrition. In many cases, if the strawberry plant grows too weakly or the harvest time is too late, then the strawberries will continue to grow, leading to aging and water loss, and consuming excessive nutrients. Therefore, we should spray foliar fertilizer in time during the flowering and fruiting stage to supplement boron, which can also improve the absorption efficiency of calcium fertilizer and is very beneficial to strawberry growth.
4. Insufficient fertilizer and water
During the fruit-setting stage, strawberries consume relatively large amounts of nutrients and water, so their requirements for fertilizer and water are also relatively high. If the supply of fertilizer and water is insufficient during the fruit-setting stage, it cannot meet the nutritional and water requirements for strawberry fruit setting, and it is also easy to cause hollow strawberries. Therefore, when growing strawberries, we should water about once a week to keep the soil moist. During the fruit expansion stage, an appropriate amount of boron fertilizer, calcium fertilizer and potassium fertilizer should be supplemented to improve the photosynthetic capacity and nutrient accumulation of strawberries. This meets the nutritional needs of strawberry fruit setting and reduces undesirable phenomena such as hollow fruit.
The above is a brief introduction to what causes hollow strawberries. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
