How to manage apple trees in autumn and winter? Management techniques of Apple trees in Autumn and Winter

Apple is a very common fruit in our daily life, and an apple tree can basically be harvested for more than ten years after planting. When planting apple trees, we should adjust the management techniques according to the changes of seasons, especially in the low temperature in autumn and winter, management is very important. So today, the editor brings you the management technology of apple trees in autumn and winter. Let's have a look!

1. Post-harvest management

Apple trees do not lose photosynthesis immediately after picking fruit in autumn and winter, so we should spray foliar fertilizer properly at this time. So as to improve the functional period of apple tree leaves and improve the nutrition accumulation of apple trees. Because most of the nutrition in the fruiting period is concentrated in the fruit, it is necessary to apply a quick-acting fertilizer in time after fruit harvest, so that the tree can restore the tree potential as soon as possible. Ensure that there is sufficient nutrition in the tree to promote the flower bud differentiation of the fruit tree in the second year. Enhance the cold and drought resistance of apple trees, and then properly spray to do a good job in pest control.

2. Applying base fertilizer in autumn

Normally, the third peak period of apple tree root growth is from September to October every year. At this time, timely fertilization is crucial to the nutrient reserve and overwintering of the tree. And the application of base fertilizer in autumn can promote the root of fruit trees to restore growth as soon as possible. We should apply sufficient organic fertilizer and control the amount of application according to the growth of fruit trees. For example, if it is a fruit tree in full fruit stage, then organic fertilizer should be applied to 4500kg, urea 50 kg and so on. The method of fertilization is used alternately with strip application and horizontal application to ensure adequate nutrition for the growth of apple trees.

3. Clear the garden in time

When apple trees are overwintering, most of the diseases, pests and pathogens in the orchard will survive the winter in the fallen leaves and buds of the fruit trees. For example, aphids lurk in the axillary buds of the same year's branches of apple trees. If autumn and winter do not do a good job in clearing the garden, such as fallen leaves and withered branches and diseased bodies, then these diseases and insect pests will become the initial source of infection in the second year of the orchard. Therefore, after harvest, we should timely remove the withered branches and fallen leaves in the orchard and bring them out of the orchard to destroy, so as to avoid harming the growth of apple trees.

4. Timely winter irrigation

In autumn and winter, it is necessary to irrigate apple trees properly in winter. Timely winter irrigation can make fertilizers and other substances decay quickly. To help trees store nutrients before winter, apple trees can usually be watered before sprouting, and the best watering time should be before freezing in winter. If there are conditions, then pour enough water to meet the water needs of apple trees. If there are no conditions, it should be watered at least once. After watering, it is necessary to properly cover some fine soil and plant straw to improve the soil moisture conservation and anti-freezing ability.

The above is a brief introduction of Apple's management technology in autumn and winter. That's all for today's introduction. This article is for reference only. I hope it can help you all.
