Causes and preventive measures of strawberry malformed fruit

Strawberry is a fruit we often eat in our daily life. With the improvement of living standards, our aesthetics has become higher. When buying strawberries, we will generally choose better color and shape. But some strawberries grow malformed, so they can't be sold, so what is the reason for strawberries' abnormal growth? Let's get to know it.

1. Abnormal flower bud differentiation.

The main factor of strawberry malformation is abnormal flower bud differentiation, which will lead to abnormal flower bud differentiation and deformed fruit if there is continuous low temperature or insufficient light during the period of flower bud differentiation. If the lack of trace elements such as calcium and boron during flowering, it will also cause abnormal floral organ development of strawberries, so the fruit is deformed.

Preventive measures: in the flower bud differentiation period to strictly control the temperature and light, the temperature should not be too much, strengthen the light intensity and time, in addition, by spraying foliar fertilizer, supplement calcium and boron to the plant to increase the flowering and seed setting rate.

2. Improper moisture

During fruit development, if the soil is too dry or too wet, the root system will be damaged and the growth and development of the fruit will be inhibited, so the fruit growth will be abnormal. In addition, in the fruit coloring period, if the plant is short of water, the fruit can not be fully expanded, and the opportunity causes the seed to float out of the fruit surface and form a deformed fruit.

Preventive measures: after the results, we should do a good job of water management, timely watering when drought, but not too much watering at one time, lest excessive humidity lead to root damage, and timely drainage in the rainy season.

3. Malnutrition

The partial application of nitrogen fertilizer during planting will lead to overgrowth of the plant, resulting in overgrowth, inhibition of reproductive growth, hindrance to the absorption of other elements, and easy to form stiff fruit, affecting yield and quality. In addition, the lack of certain elements in the reproductive growth of plants will also form stiff fruits.

Prevention method: the application of nitrogen fertilizer must be reasonable, avoid overgrowth of plants, and reasonably control the proportion of various fertilizers when fertilizing.

4. poor pollination and insemination

The main reason for strawberry malformation during poor pollination is that some varieties have poor self-pollination, which leads to poor pollination, and sometimes malformed fruit is formed due to poor pollination and fertilization due to a variety of reasons.

Preventive measures: it is best to choose varieties with high pollen fertility and large amount of pollen during cultivation, and some varieties with more pollen, high fertility, low temperature tolerance and the same flowering period can be mixed in the varieties with poor self-pollination, so as to improve the quality of pollination and fertilization. Artificial pollination or bee release can also be used to improve the quality of pollination and insemination, increase the yield and reduce the deformed fruit.
