What causes apple premature aging? Latest analysis
Everyone surely knows about apples, a very common fruit in daily life that also contains very high nutritional value and is the favorite of most people. The planting area in our country is also very wide, and there are quite a few apple varieties in our country, such as Red Delicious, Fuji, etc. But all varieties of apples will encounter one problem during the planting process, which is premature aging, and premature aging will have a huge impact on the yield and quality of apples. So what are the causes of apple premature aging? Take a look with the editor!
1. Valsa canker
Valsa canker is one of the main causes of apple premature aging. According to experiments, fruit trees suffering from Valsa canker have a rate of premature aging half higher than fruit trees without Valsa canker. It is mainly because mechanical damage to the fruit trees leads to too many wounds, or an insufficient nutrient supply is not ensured, and pest and disease control is not taken seriously, all of which will intensify the occurrence of Valsa canker and cause premature aging of the fruit trees.
2. Fertilization
Improper fertilization by growers during the planting process can also cause premature aging of the fruit trees. For example, when fruit growers fertilize, they do not control the nutrient balance of the fertilizer well. The nutrient content of the fertilizer is insufficient, or a certain fertilizer is applied in a one-sided or excessive way. This causes many fruit trees to develop obvious nutrient deficiency symptoms. Nutrient deficiency symptoms are caused by unbalanced nutrition, or insufficient fertilizer causes poor growth and development of the fruit trees due to lack of nutrients, leading to premature aging.
3. Climate
Climate change that is too rapid, or climate that is too severe, will also aggravate the premature aging phenomenon of apples. In spring and summer, the temperature rises and there is drought but little rain, or in autumn and winter, the temperature is too low but there is rainy and windy weather. These adverse weather conditions will increase the incidence of apple premature aging, so we must make emergency preparations for all sudden weather conditions.
4. Fruit thinning
A reasonable fruit thinning method is very important for apple trees. It is not that the more fruit on the tree, the better; it must be within the tree's tolerance range. If this range is exceeded, the nutrient transport of the fruit tree cannot be replenished in time, resulting in lower apple quality, and it will also have a great impact on flowering and fruiting the next year, causing the fruit tree to gradually lose vitality and begin premature aging.
5. Pruning
Although shaping and pruning is also one of the important tasks in fruit tree management, it must be determined according to factors such as the growth condition and vigor of the fruit tree. You cannot prune blindly, nor prune excessively. If shaping and pruning are carried out continuously every year, there is a high probability that abnormal conditions will occur in the growth of the fruit tree. For example, the fruiting position changes, the quality of the fruit is reduced, and the tree vigor will gradually weaken, ultimately leading to premature aging.
6. Diseases
Failure to prevent and control pests and diseases well is also a cause of apple premature aging. Fruit growers do not carry out prevention and control properly during the planting process, but only do superficial formal work carelessly. The pathogens and insect eggs in the orchard are not cleaned up thoroughly. Especially after the beginning of autumn, many people think that after the weather turns cold, the pathogens will also freeze to death, so prevention and control work is reduced even more. Therefore, the incidence of apples increases, causing harm to both the fruit and the fruit trees, leading to premature aging.
The above six points are the main causes of apple premature aging. To reduce the incidence of apple premature aging, comprehensive control should be carried out according to the above points. Reasonable fertilization, fruit thinning and pruning, etc., and strengthening orchard management. In fact, the most important thing is still pest and disease control, so that the other aspects can be effectively controlled. This will reduce the incidence of premature aging, increase yield, and improve quality.
