Causes and Solutions of Fruit trees blooming and returning in Autumn

In recent years, the phenomenon of autumn flowering of fruit trees is more common, especially in pear orchards and some poorly managed orange orchards, and some peach and plum fruit trees also blossom again in autumn, seriously affecting the yield and quality of the coming year. So for this phenomenon, it is necessary to take timely measures on the orchard to avoid reducing production in the coming year, so what is the reason why fruit trees blossom in autumn? How to solve it? Let's take a look.

1. Variety reasons

Different varieties of fruit trees have different adaptability to the external environment. If the fruit trees are not irrigated in time to resist drought in high temperature and drought in summer and autumn, then the absorption of nutrients is reduced, the growth potential is weakened, and the vegetative growth is poor. At the same time, the stress of different fruit trees to drought is also different. In Europe, which is easy to produce stress, it is more likely to blossom in autumn when the plant changes from vegetative growth to reproductive growth.

Solution: when selecting varieties, we must choose varieties with strong adaptability, strong stress resistance, strong drought resistance, disease and insect pests resistance and high yield, so as to avoid the occurrence of secondary flowering.

2. Improper management of orchards

In orchard management, if the construction is improper, the crown structure is chaotic, ventilation and light transmittance is poor, which can easily lead to diseases and insect pests, resulting in a large number of fallen leaves. The reason for early defoliation is that the accumulation of photosynthates in fruit trees is less and the storage of nutrients is low, which leads to unfavorable flower bud differentiation, enters the dormant period ahead of time, and causes secondary flowering in autumn. Sometimes orchard heavy application of chemical fertilizer, organic fertilizer is not applied or less, resulting in poor tree potential, but also lead to a large number of fallen leaves, leading to the occurrence of secondary flowering.

Solution: according to the different growth characteristics of fruit trees, rational fertilization, re-application of organic fertilizer, strengthening the tree potential, and reasonable combination of nitrogen, phosphorus and potassium fertilizer, combined with fertilization and spraying foliar fertilizer during the fruit growing period.

3. Climate impact

There is more precipitation in the orchard in summer, and the stagnant water will affect the growth and absorption capacity of fruit trees, resulting in tree weakness. if high temperature and drought weather occurs again in autumn, it will cause a large number of fallen leaves and secondary flowering of fruit trees. In November, when the spring flowers bloom, and the soil is fertile and watery, the flower buds will differentiate ahead of time and return to flowers.

Solution: for low-lying orchards to open drains, Rain Water often removes stagnant water in summer, and timely diverts water to resist drought and protect leaves in autumn.

4. Diseases and insect pests

There are many kinds of diseases and insect pests in pears, peaches, plums and other orchards. When the prevention and control is not timely or not, a large number of leaves will fall in the orchard and enter the dormant period ahead of time. When there is a lot of rainfall in autumn, in a suitable climate, a large number of flowers will bloom.

Solution: after the fruit tree enters the defoliation period and before sprouting in spring, cut off the disease and insect branches, over-dense branches, prosperous long branches, disease and insect fruits and clean the fallen leaves, bury the ashes deeply after concentrated burning, and spray stone-sulfur mixture several times in winter to reduce the base number of diseases and insects.
