Why don't strawberries blossom and bear fruit?

Why don't strawberries blossom and bear fruit? Is there any way to solve it? Netizens with strawberry planting experience are also asked to introduce that it is the season when strawberries are on the market, but the strawberries planted by some growers do not blossom or bear fruit, so the farming network has sorted out the reasons why strawberries do not blossom and bear fruit. The following are listed in detail for netizens' reference. 1. Internal factors cause: 1. Strawberry varieties are caused by the characteristics of strawberry varieties. The flower bud differentiation, flower number and flower bud number of different mature varieties are different sooner or later. 2. Nutrient factors are closely related to plant nutritional status and flower bud formation, such as excessive nitrogen and exuberant vegetative growth, which is not conducive to strawberry flower bud differentiation. 3. Growth hormone causes flower bud differentiation, which is the result of the interaction between hormones that promote flower bud differentiation and hormones that inhibit flower bud differentiation. Generally speaking, growth-promoting hormones, such as gibberellin and auxin, are not conducive to flower bud differentiation, while growth-inhibiting hormones such as abscisic acid and cytokinins can promote flower bud differentiation. 4. Caused by genetic material, genetic materials RNA and DNA control the formation of flower buds. The results showed that the increase of the proportion of RNA/DNA in many kinds of fruit trees and the decrease of ribonuclease activity were beneficial to promote flower bud differentiation. 2. External factors cause: 1. Temperature and light: low temperature and short sunshine induce flower bud formation. Most strawberry varieties began to differentiate when the daily average temperature dropped to less than 20 ℃ and the sunshine shortened to less than 12 hours. However, the differentiation was faster at 10: 17 ℃ and 10 hours of short sunshine. 2. Fertilization and watering: the flower bud differentiation of the same variety will be delayed because of too much nitrogen fertilizer, too much watering and precipitation, strong vegetative growth potential, excessive growth or too many plant leaves and insufficient leaves. 3. Plant growth regulators: artificial spraying of gibberellin can inhibit flower bud differentiation, while plant growth inhibitors and inhibitors, such as dwarf, paclobutrazol and abscisic acid, can inhibit plant growth and promote flower bud differentiation when applied to strawberry seedlings. 4. Picking leaves: the experiment shows that picking leaves of strawberry seedlings can induce flowers, and the effect of removing old leaves is more obvious than that of new leaves.
