How to manage the latest apple harvest

Apple is a kind of fruit that many people like to eat very much. In our country, the planting area of apple is very large, and its planting technology is becoming more and more mature. After entering the winter, it is time to harvest apples, and because apples are perennial plants. Therefore, it is necessary to do a good job of management after harvest to ensure the flowering and fruiting rate of the apple tree in the second year. So how to manage the apple after harvest? Let's take a look at it with the editor.

1. Early application of base fertilizer

When apple trees bear fruit, most of the nutrition will be transferred to the fruit, so the nutrients of the tree will be greatly reduced. If there is no timely fertilization, the growth of the tree becomes weaker, making it difficult for apple trees to survive the winter, and it is very easy to produce frost injury and affect the growth of apple trees. Therefore, in order to restore the growth of apple trees as soon as possible, we should apply available nitrogen fertilizer as soon as possible. It can also strengthen the growth ability of fruit tree leaves, increase the content of carbohydrates in fruit trees, ensure that apple trees have sufficient nutrition, promote flower bud differentiation in the later stage, and improve the rate of flowering and fruiting.

2. Pruning fruit trees

Pruning is also an indispensable work after harvest. We should cut off the overlong and dense branches, slender and thin branches and branches of diseases and insect pests in the crown in time after harvest. And should pay attention to the number of new sprouts in autumn, should not be too much, to prevent the consumption of too much nutrition. It is necessary to control the growth of the crown, because this is the growth period of the autumn shoot, if there are too many branches, the wound of the autumn shoot is undernourished, the healing rate becomes slower, and the overwintering of apple trees will be threatened. The main purpose of pruning is to concentrate nutrients on the trunk, promote full branches and full bud eyes, and help apple trees survive the winter successfully.

3. Preparation for overwintering

After harvesting the fruit, we gradually enter the winter, when we have to prepare the apple trees for the winter. First of all, the soil of the orchard should be turned deeply, and the depth should be mainly based on the position of the fruit tree. for example, the depth in the crown should not exceed 20 centimeters, on the contrary, it should be increased to about 40 centimeters. Then the overwintering water should be fully watered before freezing, and the watering position should be in the tree plate. Then use quicklime, salt, water and other substances to fully mix it to white the tree trunk. There are many raw materials of whitening agent, if it can not be prepared, you can buy a special whitening agent on the market.

4. Pest control

When we are pruning apple trees, we should pay attention to observe the growth of fruit branches and trunks, and find that the larvae that have drilled into the fruit trees to spend the winter should be eliminated in time. Cotton can be dipped in dichlorvos and put into the gully to kill some pests that harm the growth of apple trees. Then we should pay attention to take the pruned branches out of the orchard with fallen flowers and fruits, diseased bodies and weeds for burning and deep burial treatment. Finally, attention should be paid to the deep disinfection of the soil, reducing the number of diseases and insect pests in the orchard and destroying the overwintering places of diseases and insect pests.

The above is a brief introduction to the management methods of apple harvest. The fruit trees harvested by apples are relatively weak. If the management is not strengthened, it will seriously reduce the flowering and fruiting rate of fruit trees in the second year or even after that. Therefore, we must pay more attention to it and not neglect it. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
