Everyone knows that everything grows by the sun, and fruit trees can't grow without light. Some fruit farmers are unwilling to remove large branches in fruit tree management, and too many large branches remain, which leads to the closure of the orchard and the deterioration of the overall illumination of the orchard. Leaves don't see sunshine all the year round, and it is difficult to form flower buds without photosynthesis.
The solution is to remove shade branches year by year according to the principle of "cutting one, cutting two and not cutting three". Do not leave north and south, improve the overall illumination of fruit trees. Only when the fruit trees are ventilated and transparent can it be beneficial to the formation of flower buds and the orchard can achieve high quality and high yield.
Too many main branches affect the light.
(2) Moisture
Water has a great influence on flower bud formation, and the physiological differentiation period of flower bud in June and the morphological formation period of flower bud in September need to be strictly controlled. The orchard is not particularly dry. Try not to water it with big water, but with small water.
In these two periods, when the water content is too high, the flower buds will bloom at the top, and the spring shoots and autumn shoots can't stop growing in time, and nutrients can't be accumulated and wasted on long branches and leaves. Vegetative growth is stronger than reproduction, and it is difficult to form flower buds when branches and leaves grow in vain.
(3) fertilizing the apple trees
Fertilization of apple trees should conform to the law of fertilizer demand. There is a saying that fertilization for fruit trees is "March nitrogen fertilizer, June phosphorus fertilizer and September potassium fertilizer". Apple trees need different nutrients at different growth stages.
June is the period when fruit trees need nitrogen fertilizer. Fruit trees consume stored nutrients when they bloom and bear fruit, and nitrogen fertilizer when they branch and grow leaves after flowering. Therefore, it is necessary to supplement nitrogen fertilizer for fruit trees in March.
Phosphate fertilizer is beneficial to flower formation.
June is the flower bud differentiation period, and phosphate fertilizer needs to be supplemented. As the saying goes, "no flowers without phosphorus, no flowers and fruits are real", which fully illustrates the importance of phosphorus to flowers.
In September, in order to expand and color the fruit, potassium fertilizer needs to be supplemented. Some fruit farmers prefer nitrogen fertilizer to phosphorus fertilizer in the process of fertilization, which leads to the excessive growth of branches and the vegetative growth of trees is greater than reproductive growth. This kind of fruit tree seldom blooms.
Therefore, when applying fertilizer, we must follow the law of fertilizer demand for fruit trees, and more flowers will bloom with high phosphorus fertilizer.
(4) Pruning
The purpose of apple tree pruning is to open the light path and improve the ventilation and light transmission of the orchard. Excessive pruning will cause trees to flourish and make it difficult to bloom.
fruit tree pruning
To sum up, there are many reasons why apple trees don't bloom. It is closely related to the illumination conditions, moisture, nutrients and pruning of the orchard. To solve the problem of fewer flowers in apple trees, we should start from the above four points. I am a small farmer, that's my opinion.
