What causes deformed strawberries? How to prevent them

Strawberries are a fruit we commonly eat in daily life. As living standards improve, our aesthetic standards have also risen, and when buying strawberries we generally choose those with better color and shape. But some strawberries grow deformed, so they cannot be sold. So what causes deformed strawberry growth? Let's find out together.

1. Abnormal flower bud differentiation

The main factor behind deformed strawberries is abnormal flower bud differentiation. If the flower bud differentiation stage encounters sustained low temperatures or insufficient light, it will cause abnormal flower bud differentiation, thus producing deformed fruit. If calcium, boron and other trace elements are lacking during flowering, it will also cause abnormal development of strawberry floral organs, so the fruit becomes deformed.

Preventive measures: During the flower bud differentiation stage, temperature and light must be strictly controlled. The temperature should not be too high, and light intensity and duration should be increased. In addition, foliar fertilizer can be sprayed to supplement the plant with calcium and boron elements, increasing the flowering and fruiting rate.

2. Improper moisture

During fruit development, if the soil is too dry or the humidity is too high, it will cause root damage, and the growth and development of the fruit will be inhibited, so the fruit grows deformed. In addition, during the fruit coloring stage, if the plant lacks water, the fruit cannot fully expand, which can cause the seeds to protrude from the fruit surface, forming deformed fruit.

Preventive measures: After fruiting, do a good job of water management. Water promptly during drought, but do not water too much at one time, so as to avoid excessive humidity damaging the roots. Drain promptly during the rainy season.

3. Nutritional imbalance

During planting, if nitrogen fertilizer is applied excessively, it will cause excessive plant growth, leading to leggy growth, inhibited reproductive growth, and blocked absorption of other elements, making it very easy to form stiff fruit, affecting yield and quality. In addition, a lack of certain elements during the plant's reproductive growth will also form stiff fruit.

Preventive methods: The application of nitrogen fertilizer must be reasonable to avoid leggy growth of the plant, and the proportion of various fertilizers should be reasonably controlled when fertilizing.

4. Poor pollination and fertilization

Poor pollination and fertilization is the main cause of deformed strawberries. Some varieties have poor self-pollination, leading to poor pollination, while in other cases various reasons cause poor pollination and fertilization, thus forming deformed fruit.

Preventive measures: When cultivating, it is best to choose varieties with high pollen fertility and a large amount of pollen. In addition, for varieties with poor self-pollination, some varieties with more pollen, higher fertility, low-temperature tolerance, and the same flowering period can be planted mixed in, which can improve the quality of pollination and fertilization. Artificial pollination or bee pollination can also be used to improve the quality of pollination and fertilization, increase yield, and reduce deformed fruit.
