Causes and preventive measures of strawberry fruit

Strawberry fruit is a common phenomenon in strawberry planting, under normal pollination, strawberry fruit will expand rapidly, but pollination has not expanded for a long time, and the fruit has signs of blackening, it is very likely to be the symptom of stiff fruit. So what about strawberries and nuts? Let's take a look.

First, the cause of stiff fruit.

1. Temperature

Temperature has a great effect on the growth of strawberry, if the temperature is too high in the seedling stage, it will cause poor flower bud differentiation, easy to form thin flowers, and will form stiff fruit and small fruit in the later stage. The temperature at flowering stage will also affect the pollination of strawberries. Poor pollination may hinder the formation of jelly between seeds and pulp. When the fruit expands, due to the lack of nutrient supply, the fruit expands slowly and is easy to form stiff fruit.

2. Lack of light

When the fruit expands, if there is continuous overcast and rainy weather, it will affect the photosynthesis of strawberry, lead to nutrient synthesis and watering, unable to supply fruit growth, and lead to the phenomenon of stiff fruit in some fruits.

3. Improper fertilization

The partial application of nitrogen fertilizer at the seedling stage will lead to overgrowth of strawberries, loss of nutrition balance, inhibition of reproductive growth, and also affect the absorption of other elements by the plant, such as zinc, boron and other trace elements necessary for fruit growth. when the fruit really lacks them, it will stop growing and form a stiff fruit.

4. Improper management

If the water and fertilizer is irrigated too late or the flowers and fruits grow too vigorously, the third and fourth inflorescences will be irrigated if there is no timely thinning of flowers and fruit. this is because the development is too late and the nutrients are preempted by the first two layers of inflorescences, resulting in the lack of nutrients in the latter layer and gradually ossified. In addition, when the plant is short of water, it will also cause stiff fruit.

5. Diseases and insect pests

Some insect pests absorb the water and nutrients in the fruit, which causes the fruit to form a stiff fruit because it does not have enough water and nutrients to grow.

II. Preventive measures

In the whole growing period of strawberries, the temperature should be reasonably controlled, and when the temperature is too high in the seedling stage, ventilation should be strengthened, temperature and humidity should be reduced, low temperature should be reduced, and heat preservation measures should be taken well, as well as in flowering and fruit stage. Increasing the application of organic fertilizer can improve root activity and promote plant growth. in overcast and rainy weather, artificial light supplement measures should be carried out properly to strengthen plant photosynthesis, promote nutrient synthesis, prevent stiff fruit, and strengthen water management. watering during drought and timely drainage after rain. The prevention and control of diseases and insect pests should not be ignored, and timely prevention and control of diseases and insect pests should be found.
