Detailed explanation of the causes and prevention measures of abnormal strawberry fruits

During their growth, strawberries can develop many abnormal fruits, and these abnormal fruits can seriously affect strawberry yield and quality, bringing huge losses to growers. So what causes these abnormal fruits? And how can they be prevented? Let's take a look together.

1. Deformed fruit

Strawberry deformed fruit mainly refers to fruit whose shape develops abnormally, and it is the most common type of abnormal strawberry fruit, with an incidence rate of about 30% to 40%, and up to 60% at most. The main cause is incomplete pollination and fertilization, which leads to uneven fruit development and the formation of deformed fruit.

Prevention methods: Choose varieties with strong pollen germination ability, and plant multiple varieties with abundant pollen and strong pollen germination ability together, which can greatly reduce the probability of deformed fruit. Water appropriately during the flowering period, ventilate and exchange air in time, and maintain suitable temperature and humidity to facilitate pollen germination and increase yield. During the flowering period, strictly control pests and diseases, choose pesticides with less phytotoxicity as much as possible, and spray when there are fewer flowers.

2. Obese fruit

Obese fruit refers to fruit that is too large and fat, with large and soft fruit, bland flavor, poor quality, and poor storability. The cause of obese fruit is that from fruit expansion to harvest, excessive topdressing leads to excessive vegetative growth, causing the plant to grow leggy and the fruit to expand rapidly.

Prevention methods: When the plant is growing and developing well, there is no need to fertilize in summer. If fertilization is necessary, it should also wait until after the peak harvest period of the terminal inflorescence.

3. Fruit with protruding seeds

This refers to fruit with seeds protruding from the fruit surface. This kind of fruit has poor appearance quality, a sour and astringent taste, and relatively high hardness. Soil drought, weak plant growth, and a high-temperature environment can all cause fruit with protruding seeds.

Prevention methods: During cultivation and management, pay attention to controlling the environmental temperature and the fertilizer and water conditions to reduce the occurrence of protruding fruit in the plant.

4. Green-top fruit

Green-top fruit is a strawberry fruit whose lower part has matured and turned red, while the upper tip is not yet ripe and still green. It reduces fruit quality, delays the picking period, and affects the time to market. When strawberries show a tendency toward excessive growth, with luxuriant branches and leaves, and then encounter cloudy and rainy days with insufficient light, green-top fruit is very likely to occur.

Prevention methods: Therefore, prevent excessive strawberry growth, remove aged branches and leaves in time, and promote ventilation and light penetration. At the same time, while maintaining the indoor temperature, uncover the straw matting early and cover it late as much as possible to extend the lighting time and prevent the occurrence of green-top fruit.
