Reasons for the phenomenon of the size of fruit trees

When it comes to big and small years, I believe many of them are not new to them, especially fruit trees, which often produce more and less in one year. If there is a high yield this year, then there may be low yield or no fruit every year. If this phenomenon is not prevented in time, it may form a vicious circle, which will greatly shorten the life span of fruit trees and seriously affect the economic benefits of fruit farmers. So what is the reason for the age of fruit trees? Let's get to know it.

1. Extreme climate

During the growth and development of fruit trees, normal fruit trees in extreme drought, excessive precipitation, abnormal freezing injury, hail and late spring cold and other bad weather will lead to the weakening of trees in the second year. the number of blossoms and fruits is seriously reduced or there is a phenomenon of falling flowers and fruits in a large area, resulting in a reduction in production into a small year. After a small year, the number of fruit is less, and the consumption of nutrients is less, so the tree accumulates more nutrients, which will bear fruit in the next year, resulting in a big year.

2. Tree load

Many fruit growers believe that fruit trees blossom and bear fruit over the winter, the higher the yield in the later stage, so they are reluctant to thinning flowers and fruits in the young fruit stage, which is also the main reason for normal-sized years. The excessive number of flowering and fruit setting of fruit trees will consume a lot of tree nutrients, resulting in the loss of balance between vegetative growth and reproductive growth, resulting in the decrease of branch growth nutrients, and the flower bud differentiation of fruit trees will be restrained, which will lead to the number of blossoms and fruits of fruit trees in the second year. There is a small year, followed by a big year.

3. Improper pruning

Fruit growers do not pay attention to pruning methods when pruning, such as the unreasonable ratio of vegetative branches to fruiting branches, or light or heavy pruning of fruits year after year, pruning methods like this may cause the phenomenon of big and small years.

4. Variety characteristics

Different varieties of fruit trees have different growth characteristics, so the probability of occurrence of large and small years is also different, for example, the probability of fruit trees size of early and middle maturity varieties is lower, while that of late maturity varieties is higher; adult and old fruit trees are more serious than young fruit trees The common pear trees, persimmon trees and drupe and small berry fruit trees in our life are lighter in size, but grape, peach, jujube, pomegranate and other fruit trees are very easy to produce age information, so we should pay attention to it when planting.
