The causes and Solutions of the latest Fruit trees blooming in Autumn

In recent years, the phenomenon of fruit trees blooming back in autumn is more common, especially in pear orchards and some poorly managed orchards. In addition, some peach and plum trees also bloom again in autumn, which seriously affects the yield and quality of next year. Therefore, for this phenomenon, measures should be taken in time for orchards to avoid yield reduction in the coming year. What is the reason for fruit trees to bloom back in autumn? How do we solve this? Let's take a look.

1. Reasons for variety

Different varieties of fruit trees have different adaptability to the external environment. If the fruit trees are not watered in time for drought resistance in summer and autumn, the nutrient absorption of fruit trees will decrease, the growth potential will weaken, and the nutrient growth will be poor. Meanwhile, different fruit trees have different stress to drought. In Europe, where stress is easy to occur, the possibility of flowering in autumn is high when the plant turns from vegetative growth to reproductive growth.

Solution: When selecting varieties, we must choose varieties with strong adaptability, strong stress resistance, drought resistance, pest resistance and high yield, so as to avoid secondary flowering.

2. Improper orchard management

If the orchard is not properly built, the crown structure is chaotic, the ventilation and light transmittance are poor, and it is easy to cause pests and diseases, causing a large number of leaves. The reason for early defoliation is that the accumulation of photosynthetic products is less, the nutrient storage of trees is low, which leads to unfavorable flower bud differentiation, enters dormancy stage ahead of time, and initiates the second flowering in autumn. Sometimes orchard heavy fertilizer, organic fertilizer is not applied or applied less, resulting in poor tree vigor, but also cause a large number of leaves, promote the second flowering phenomenon.

Solution: To different growth characteristics of fruit trees, reasonable fertilization, heavy application of organic fertilizer, enhance tree vigor, and reasonable combination of nitrogen, phosphorus and potassium fertilizers, combined with fertilization and foliar fertilizer during fruit growth period.

3. Climate impact

Summer orchard precipitation is more, ponding will affect the growth and absorption capacity of fruit trees, resulting in tree weakness, if autumn again encounter high temperature and drought weather, will cause a large number of fruit trees deciduous and secondary flowering. In November, when the climate is warm spring flowers bloom, and soil fertilizer and water are sufficient, flower buds will also differentiate ahead of time and bloom back.

Solution: For low-lying orchards, open drainage ditches, timely drainage of accumulated water in summer, and timely diversion of water to drought and leaf protection in autumn drought.

4. Pest damage

Pear, peach, plum and other orchards harm many kinds of diseases and insect pests, in the prevention and control is not timely or not to be prevented, often to the orchard a large number of leaves, early into the dormant period, when the autumn rainfall, in a suitable climate, a large number of flowers will bloom back.

Solution: After the fruit trees enter the deciduous period and before budding in spring, cut off the diseased branches, over-dense branches, flourishing branches, diseased fruits and clean the fallen leaves, bury the ashes deeply after centralized burning, spray the stone sulfur mixture several times in winter to reduce the number of diseases and insect pests.

The above is the introduction of the reasons and solutions for fruit trees to bloom in autumn. I hope it can help you. If you want to know more about relevant knowledge, please pay attention to us.
