Does it matter if it rains during the flowering of apple trees?
From years of planting experience, it is clear when it rains during flowering period, and the impact will not be too great. However, the continuous rainy weather will probably have a great impact on the flowering apple trees, mainly in the following aspects.
1. The rain at the flowering stage of apple mainly affects pollination.
It rains at the flowering stage of apple trees, and the pollen is wet, so it is not easy to be carried away by the wind, and it is impossible to complete wind-borne pollination. Moreover, in rainy days, insects such as bees can't go out to collect pollen, which also blocks the way for insect vectors to enter pollination.
In this way, if the apple tree is not pollinated well, it will be full of flowers and the fruit setting rate will be low. Everyone can understand this, so I won't go into details.
2. When it rains during the flowering period of apple trees, many diseases will occur and spread in large quantities.
Because of the heavy rainfall and humidity in the orchard during flowering, apple trees are prone to many diseases. Mainly flower rot, mold heart disease, spot defoliation, brown spot disease and rust.
Judging from the planting years, there was more rain in March and April, and the water in the orchard was larger. The above diseases are quite serious.
As far as last year's situation is concerned, mold heart disease, brown spot disease and mottled defoliation are all very serious. As soon as we entered June, we began to lose a lot of leaves.
In particular, our marshal in Tianshui area fell leaves seriously in the early stage, and very early, when we were busy picking peppers, it was quite serious when it was discovered later.
Although it has been treated many times, the effect is very bad. I used the right medicine in the early stage, and my condition was mild. Most fruit trees have few leaves.
Later, Fuji apples also fell leaves, especially when they were just bagged. Later, when I picked it, I found that the mold heart disease was also quite serious.
Therefore, if there is a lot of rain in the flowering period of apple trees, the impact will be great. In addition to affecting pollination, it is more important that the occurrence of the above diseases is related to precipitation. The more rain, the more serious the disease.
Therefore, we fruit farmers should pay more attention to prevent the above diseases in time once there is more rain in flowering and young fruit period. If the leaves of apple trees fall off early, there will be more problems and black spots.
