The causes of premature senescence of apple

Apple is certainly known to all, a very common fruit in life and also contains very high nutritional value, is most people's favorite. Planting area in China is also very wide, China's apple species are also many, such as snake fruit, Fuji and so on. However, all varieties of apples will encounter a problem in the planting process, that is, premature aging, which will have a great impact on the yield and quality of apples. So what causes premature apple aging? Take a look at it with Xiaobian!

1. Rot disease

Rot disease is one of the main causes of premature aging of apples. According to experiments, fruit trees with rot disease have a higher probability of premature aging than fruit trees without rot disease. It is mainly due to the mechanical damage of fruit trees resulting in too many wounds, or insufficient nutrition supply, lack of attention to pest control, etc., which will aggravate the occurrence of rot disease and cause premature aging of fruit trees.

2. Fertilization

Improper fertilization by growers during planting can also lead to premature aging of fruit trees, for example, fruit growers do not control the nutrient balance of fertilizer when fertilizing. Fertilizer nutrient content is insufficient, partial application or excessive application of a certain fertilizer. Many fruit trees have obvious nutrient deficiency, which is caused by uneven nutrition, or insufficient fertilizer, and the lack of nutrition and development of fruit trees leads to premature aging.

3. Climate

Rapid climate change, or severe weather, can also exacerbate premature apple aging. Spring and summer when the temperature rises dry but less rain, or autumn and winter when the temperature is too low but there is rainy and windy weather. These bad weather will increase the incidence of premature apple aging, so we have to do all the emergency measures for sudden weather.

4. Fruit thinning

A reasonable fruit thinning method is very important for apple trees, not the more fruits on the fruit trees, but within the bearing range of the fruit trees. If it exceeds this range, it will make the nutrient transportation of fruit trees unable to be supplemented in time, resulting in the reduction of apple quality, and will also have a great impact on the flowering and fruiting of the next year, resulting in the gradual loss of vitality of fruit trees and the beginning of premature aging.

5, pruning

Although pruning is also an important part of fruit tree management, it depends on factors such as the growth and growth of fruit trees. Do not prune blindly, and do not over-prune. If you continue to prune every year, there is a high probability that the growth of fruit trees will be abnormal. For example, the fruit position changes, reducing the quality of the fruit, the tree vigor will gradually weaken, and eventually lead to premature aging.

6. Diseases

Failure to prevent and control diseases and insect pests is also the reason for premature aging of apples. Fruit farmers do not have proper prevention and control in the planting process, but do some formal work carelessly. The germs and eggs in the orchard are not clear, especially after autumn, many people think that the germs will freeze to death after the weather gets cold, and the prevention and control work is reduced. Therefore, it leads to an increase in the incidence of apple disease, causing harm to fruit trees and premature aging.

The above six points are the main reasons for premature apple aging. To reduce the incidence of premature apple aging, comprehensive prevention and control should be carried out according to the above points. Reasonable fertilization, thinning fruit pruning, etc., strengthen orchard management, in fact, the most important thing is to prevent diseases and insect pests, so as to effectively control the rest of the aspects. Reduce the premature aging rate, increase the yield and improve the quality.
