What is the reason why the latest strawberries don't bear fruit?

Strawberry market demand is large, economic benefits are high, so there are more growers, but some growers do not bear fruit in the planting process, which is bad for fruit growers. So why don't strawberries bear fruit? Let's take a look.

I. Internal factors

1. Variety characteristics

The varieties with different mature stages have different flower bud differentiation sooner or later, the number of differentiated flowers and flower buds are different, so it is very important to select the variety of strawberry, and the quality of flowering also determines the fruit quality of strawberry.

2. Nutrients

Plant nutritional status is closely related to flower bud formation. Before flower bud differentiation, the increase of sufficient ratio of carbohydrate to nitrogen is beneficial to flower bud differentiation, on the contrary, flower bud differentiation is later. The flower bud differentiation period of strong seedlings is earlier than that of weak seedlings, and the number of florets increases correspondingly, with too much nitrogen and exuberant vegetative growth, which is not conducive to flower bud differentiation.

3. Growth regulators

Strawberry flower bud differentiation is the result of the interaction between hormones that promote flower bud differentiation and hormones that inhibit flower bud differentiation. Generally, growth-promoting hormones, such as gibberellin and auxin, are not conducive to flower bud differentiation; on the contrary, hormones that inhibit growth, such as abscisic acid and cytokinins, can promote flower bud differentiation.

II. External factors

1. Light and temperature

Temperature and light affect photosynthesis, respiration and other physiological functions of strawberry, which are related to plant nutrition and flower bud differentiation, while low temperature and short day light induce flower bud formation, while most strawberry varieties are induced under low temperature and short day light. begin flower bud differentiation.

2. Watering and fertilizing

On the basis of the same variety, because of excessive application of nitrogen fertilizer, more watering or rainfall, the vegetative growth potential of the plant is strong, and excessive growth or too many leaves and insufficient leaves will delay flower bud differentiation. Therefore, try not to irrigate a large amount of water or apply too much nitrogen fertilizer, so as to avoid greedy green late ripening and less nutrient accumulation, thus affecting the quality of flower bud differentiation.

3. Spraying plant growth regulators

Artificial spraying of gibberellin could inhibit flower bud differentiation, while plant growth inhibitors and inhibitors, such as dwarf, paclobutrazol and abscisic acid, could inhibit plant growth and promote flower bud differentiation.

4. Picking leaves

Picking leaves can induce flower formation, and the effect of removing old leaves is more obvious than that of new leaves, because old leaves contain more flower formation inhibitory substances, which can reduce their content after removal, reduce nutrient consumption and increase accumulation, so as to promote flower bud differentiation. Therefore, it is necessary to grasp the moderation of leaf picking in production so as not to cause unfruitful results.

The above is the introduction of the reason why strawberries are unfruitful. I hope I can help you. If you want to know more about it, please follow us.
