The latest causes of premature senescence of Apple

Apple, as we all know, is a very common fruit in life and has a very high nutritional value, which is the favorite of most people. The planting area is also very wide in our country, and there are many kinds of apples in our country, such as snake fruit, Fuji and so on. However, all varieties of apples will encounter a problem in the process of planting, that is, premature senescence will have a great impact on the yield and quality of apples. So what are the reasons for Apple's premature senility? Take a look at it with the editor.

1. Rot disease

Rot is one of the main causes of premature senescence of apples. according to experiments, the incidence of premature senescence of fruit trees with rot is half higher than that of fruit trees without rot. Mainly due to the mechanical damage of fruit trees lead to too many wounds, or do not ensure adequate nutrition supply, do not pay attention to the prevention and control of diseases and insect pests, will be the aggravation of rot, resulting in premature senescence of fruit trees.

2. Fertilization

Growers in the planting process of improper fertilization will also lead to premature senescence of fruit trees, such as fruit farmers do not control the nutritional balance of fertilizer. Fertilizer nutrient content is insufficient, partial application or over-application of a certain kind of fertilizer. As a result, many fruit trees have obvious nutrient deficiency, which is caused by uneven nutrition, or lack of fertilizer, lack of nutrition and poor development of fruit trees lead to premature senility.

3. Climate

The speed of climate change is too fast, or the climate is too bad, it will also aggravate the premature senility of apples. In spring and summer, the temperature rises dry but there is little rain, or in autumn and winter, the temperature is too low but there is rainy and windy weather. These bad weather will increase the incidence of premature senility of Apple, so we should take all emergency measures for sudden weather.

4. Fruit thinning

A reasonable way of fruit thinning is very important for apple trees, not that the more fruit on the fruit tree, the better, it should be within the bearing range of the fruit tree. If it goes beyond this range, the nutrition transport of fruit trees can not be replenished in time, resulting in a decline in the quality of apples, but also a great impact on the flowering and fruiting of the second year, resulting in the gradual loss of vitality and premature senescence of fruit trees.

5. Pruning

Although shaping and pruning is also one of the important tasks in the management of fruit trees, it depends on the growth and growth of fruit trees. Can not be blindly pruned, nor excessive pruning, if the continuous pruning every year, there is a good chance that the growth of fruit trees will be abnormal. For example, if the fruit position changes, the quality of the fruit will be reduced, and the tree potential will gradually weaken, resulting in premature senescence.

6. Disease

Failure to prevent and control diseases and insect pests is also the reason for the premature senescence of apples, fruit growers do not put in place prevention and control in the planting process, but carelessly do some formal work. The germs and eggs in the orchard are not clear and clean, especially after the beginning of autumn, many people think that the germs will freeze to death after the weather gets cold, and the prevention and control work will be reduced. Therefore, it leads to an increase in the incidence of apples, which is harmful to fruit trees and leads to premature senescence.

The above six points are the main causes of apple premature senility. Comprehensive prevention and treatment should be carried out according to the above points in order to reduce the incidence of apple premature senility. Rational fertilization, fruit thinning and pruning, etc., to strengthen the management of orchards, in fact, the most important thing is to control diseases and insect pests, so as to effectively control the rest of the aspects. It can reduce the incidence of premature senility, increase the yield and improve the quality.
