Strawberries in China's planting area is large, loved by many people, so its market demand is also very large. However, although there are more people growing strawberries, there are often many problems when growing strawberries, and hollow is one of them. If the strawberry is hollow, the yield will be greatly affected. So today we will see how to avoid the production of hollow fruit.
What is strawberry hollow fruit
A hollow fruit is a fruit with a hollow core between the pulp gums. It is mainly manifested as the hollowness of the fruit; it will affect the commerciality of strawberries. Therefore, in terms of production, we can take measures to prevent it.
The cause of the hollow fruit
There are many reasons for the hollow fruit, except for the variety reason, what other reasons can cause the strawberry fruit to be hollow?
First, insufficient light. If in the autumn, winter or early spring season, there is even rainy weather, the light is insufficient, the photosynthetic product is reduced, and the nutrient supply inside the fruit is insufficient, which is easy to produce hollow fruit.
Second, during the flowering and fruit setting period, if the shed temperature is too high (more than 35 ° C and the duration is long), or too low, resulting in poor pollen fertilization, the cell division of the pulp tissue in fruit development is accelerated, and the seed will form hollow fruit due to poor fertilization and fruit growth rate.
Third, if the fertilizer water supply is insufficient during the fruit setting period, the nutritional status of the plant cannot meet the needs of fruit expansion and can easily lead to the formation of hollow fruit.
Fourth, the lack of boron elements. Boron plays an important role in promoting the transport of nutrients within the fruit, and if there is a lack of boron and the pulp is insufficient, it will also form a hollow fruit.
How to avoid the production of hollow fruit
First, keep the shed film clean, to prevent the film surface from attaching water droplets and dust, the ground is laid with silver gray film or aluminum foil or reflective curtain, increase the intensity of light between plants, you can also use plant special fill lights, or incandescent lamps for filling light.
Second, maintain a reasonable temperature in the shed, such as the temperature is too high, to carry out ventilation and cooling in time, when the temperature is too low in winter, we should pay attention to the use, cover the grass, burn solid alcohol, warming block, etc. to increase the temperature to ensure the appropriate growth temperature.
Third, after the strawberry enters the flowering period, a balanced fertilizer (3-5 catties per mu) should be applied to promote more flowering and fruit setting. In general, it is necessary to ensure that watering is carried out once a week, the amount of watering should be relatively sufficient, and the watering time should be as far as possible in the morning, so that enough time can be used to restore the ground temperature.
Fourth, the early flowering stage, young fruit stage, fruit expansion stage need to start foliar supplementation of amino acid fertilizer and calcium, boron fertilizer, early application can improve the absorption efficiency of calcium fertilizer, not only increase the sweetness and aroma of strawberries, can improve fruit hardness, improve the shelf life of strawberries.
The above is a brief introduction to the strawberry hollow fruit. Today's introduction is here, this article is for reference only, I hope to help you Oh!
