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 the yield and quality of strawberries, bringing huge losses to fruit growers. So what causes these abnormal fruits? And how can they be prevented? Let us understand together.
1. Deformed fruit
Strawberry deformed fruit mainly refers to fruit whose shape develops abnormally, and it is the most common among abnormal strawberry fruits, 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 a large amount of 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, try to choose pesticides with less phytotoxicity, and spray when there are fewer flowers.
2. Obese fruit
Obese fruit refers to fruit that is excessively large and fat, with large and soft fruit, bland flavor, poor quality, and poor storability. The cause of obese fruit is that from fruit enlargement to harvest, excessive topdressing causes excessive vegetative growth, resulting in spindly growth of the plant and rapid fruit enlargement.
Prevention methods: When the plant is growing and developing well, there is no need to fertilize in summer. If fertilization is needed, wait until after the peak harvest period of the terminal inflorescence.
3. Seed-protruding fruit
This is fruit with seeds protruding from the fruit surface. This kind of fruit has poor appearance quality, a sour and astringent taste, and relatively high firmness. Soil drought, weak plant growth, and high-temperature environments can all cause seed-protruding fruit.
Prevention methods: During cultivation 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 strawberry fruit in which the lower part matures and turns red, while the upper tip is not 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 growth of strawberries, remove aging branches and leaves in time, promote ventilation and light penetration, and at the same time, while maintaining the indoor temperature, uncover the straw mats early and cover them late as much as possible to extend the lighting time and prevent the occurrence of green-top fruit.
